Accounting Policies [Abstract]
Company Background	1	COMPANY BACKGROUND:
	We are the largest recreational boat retailer in the United States. We engage primarily in the retail sale, brokerage, and service of new and used boats, motors, trailers, marine parts and accessories and offer slip and storage accommodations in certain locations. In addition, we arrange related boat financing, insurance, and extended service contracts. We recently implemented programs to increase sales of boats, boating parts, and accessories, as well as the offer of finance and insurance, or F&I, products at various offsite locations; and the charter of power and sailing yachts in the British Virgin Islands. None of these recently implemented programs have had a material effect on our condensed consolidated financial statements. As of March 31, 2015, we operated through 53 retail locations in 16 states, consisting of Alabama, California, Connecticut, Florida, Georgia, Maryland, Minnesota, Missouri, New Jersey, New York, North Carolina, Ohio, Oklahoma, Rhode Island, Tennessee, and Texas. Our MarineMax Vacations operations maintain a facility in Tortola, British Virgin Islands.
	We are the nation’s largest retailer of Sea Ray, Boston Whaler, and Meridian recreational boats and yachts, all of which are manufactured by Brunswick Corporation (“Brunswick”). Sales of new Brunswick boats accounted for approximately 40% of our revenue in fiscal 2014. Sales of new Sea Ray and Boston Whaler boats, both divisions of Brunswick, accounted for approximately 26% and 10%, respectively, of our revenue in fiscal 2014. Brunswick is the world’s largest manufacturer of marine products and marine engines. We believe we represented approximately 43% of Brunswick’s Sea Ray boat sales, during our fiscal 2014.
	We have dealership agreements with Sea Ray, Boston Whaler, Meridian, and Mercury Marine, all subsidiaries or divisions of Brunswick. We also have dealer agreements with Italy-based Azimut-Benetti Group’s product line for Azimut Yachts. These agreements allow us to purchase, stock, sell, and service these manufacturers’ boats and products. These agreements also allow us to use these manufacturers’ names, trade symbols, and intellectual properties in our operations.
	We have multi-year dealer agreements with Brunswick covering Sea Ray products that appoints us as the exclusive dealer of Sea Ray boats in our geographic markets. We are the exclusive dealer for Boston Whaler through multi-year dealer agreements for many of our geographic markets. In addition, we are the exclusive dealer for Azimut Yachts for the entire United States through a multi-year dealer agreement. Sales of new Azimut boats accounted for approximately 14% of our revenue in fiscal 2014. We believe non-Brunswick brands offer a migration for our existing customer base or fill a void in our product offerings, and accordingly, do not compete with the business generated from our other prominent brands.
	As is typical in the industry, we deal with manufacturers, other than Sea Ray, Boston Whaler, Meridian, and Azimut Yachts, under renewable annual dealer agreements, each of which gives us the right to sell various makes and models of boats within a given geographic region. Any change or termination of these agreements, or the agreements discussed above, for any reason, or changes in competitive, regulatory, or marketing practices, including rebate or incentive programs, could adversely affect our results of operations. Although there are a limited number of manufacturers of the type of boats and products that we sell, we believe that adequate alternative sources would be available to replace any manufacturer other than Sea Ray and Azimut as a product source. These alternative sources may not be available at the time of any interruption, and alternative products may not be available at comparable terms, which could affect operating results adversely.
	General economic conditions and consumer spending patterns can negatively impact our operating results. Unfavorable local, regional, national, or global economic developments or uncertainties regarding future economic prospects could reduce consumer spending in the markets we serve and adversely affect our business. Economic conditions in areas in which we operate dealerships, particularly Florida in which we generated approximately 49%, 51%, and 52% of our revenue during fiscal 2012, 2013, and 2014, respectively, can have a major impact on our operations. Local influences, such as corporate downsizing, military base closings, inclement weather such as Hurricane Sandy, environmental conditions, and specific events, such as the BP oil spill in the Gulf of Mexico, also could adversely affect, and in certain instances have adversely affected, our operations in certain markets.
	In an economic downturn, consumer discretionary spending levels generally decline, at times resulting in disproportionately large reductions in the sale of luxury goods. Consumer spending on luxury goods also may decline as a result of lower consumer confidence levels, even if prevailing economic conditions are favorable. As a result, an economic downturn could impact us more than certain of our competitors due to our strategic focus on a higher end of our market. Although we have expanded our operations during periods of stagnant or modestly declining industry trends, the cyclical nature of the recreational boating industry or the lack of industry growth may adversely affect our business, financial condition, and results of operations. Any period of adverse economic conditions or low consumer confidence has a negative effect on our business.
	Lower consumer spending resulting from a downturn in the housing market and other economic factors adversely affected our business in fiscal 2007, and continued weakness in consumer spending and depressed economic conditions had a substantial negative effect on our business in each subsequent fiscal year. These conditions have caused us to substantially reduce our acquisition program, delay new store openings, reduce our inventory purchases, engage in inventory reduction efforts, close a number of our retail locations, reduce our headcount, and amend and replace our credit facility. Acquisitions and new store openings remain important strategies to our company, and we plan to accelerate our growth through these strategies when more normal economic conditions return. However, we cannot predict the length or severity of these unfavorable economic or financial conditions or the extent to which they will continue to adversely affect our operating results nor can we predict the effectiveness of the measures we have taken to address this environment or whether additional measures will be necessary.

Basis of Presentation	2	BASIS OF PRESENTATION:
	These unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States for interim financial information, the instructions to Quarterly Report on Form 10-Q, and Rule 10-01 of Regulation S-X and should be read in conjunction with our Annual Report on Form 10-K for the fiscal year ended September 30, 2014. Accordingly, these unaudited condensed consolidated financial statements do not include all of the information and footnotes required by accounting principles generally accepted in the United States for complete financial statements. All adjustments, consisting of only normal recurring adjustments considered necessary for fair presentation, have been reflected in these unaudited condensed consolidated financial statements. As of March 31, 2015, our financial instruments consisted of cash and cash equivalents, accounts receivable, accounts payable, customer deposits, and short-term borrowings. The carrying amounts of our financial instruments reported on the balance sheet as of March 31, 2015 approximated fair value due either to length to maturity or existence of variable interest rates, which approximate prevailing market rates. The operating results for the three and six months ended March 31, 2015 are not necessarily indicative of the results that may be expected in future periods.
	The preparation of unaudited condensed consolidated financial statements in conformity with accounting principles generally accepted in the United States requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the unaudited condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting periods. Significant estimates made by us in the accompanying unaudited condensed consolidated financial statements include valuation allowances, valuation of goodwill and intangible assets, valuation of long-lived assets, and valuation of accruals. Actual results could differ from those estimates.
	Unless the context otherwise requires, all references to “MarineMax” mean MarineMax, Inc. prior to its acquisition of five previously independent recreational boat dealers in March 1998 (including their related real estate companies) and all references to the “Company,” “our company,” “we,” “us,” and “our” mean, as a combined company, MarineMax, Inc. and the 24 recreational boat dealers, two boat brokerage operations, and two full-service yacht repair operations acquired to date (the “acquired dealers,” and together with the brokerage and repair operations, “operating subsidiaries” or the “acquired companies”).
	The unaudited condensed consolidated financial statements include our accounts and the accounts of our subsidiaries, all of which are wholly owned. All significant intercompany transactions and accounts have been eliminated.

Accounting Changes and Error Corrections [Abstract]
New Accounting Pronouncements	3	NEW ACCOUNTING PRONOUNCEMENTS:
	In May 2014, the FASB issued Accounting Standards Update No. 2014-09, “Revenue from Contracts with Customers (Topic 606)” (ASU 2014-9), a converged standard on revenue recognition. The new pronouncement requires revenue recognition to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The guidance also specifies the accounting for some costs to obtain or fulfill a contract with a customer, as well as enhanced disclosure requirements. ASU 2014-9 is effective for annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. Early adoption is not permitted. We currently do not believe the adoption of this standard will have a material impact on our consolidated financial statements.

Revenue Recognition	4	REVENUE RECOGNITION:
	We recognize revenue from boat, motor, and trailer sales, and parts and service operations at the time the boat, motor, trailer, or part is delivered to or accepted by the customer or the service is completed. We recognize deferred revenue from service operations and slip and storage services on a straight-line basis over the term of the contract or when service is completed. We recognize commissions earned from a brokerage sale at the time the related brokerage transaction closes. We recognize commissions earned by us for placing notes with financial institutions in connection with customer boat financing when we recognize the related boat sales. We recognize marketing fees earned on credit, life, accident, disability, gap, and hull insurance products sold by third-party insurance companies at the later of customer acceptance of the insurance product as evidenced by contract execution or when the related boat sale is recognized. Pursuant to negotiated agreements with financial and insurance institutions, we are charged back for a portion of these fees should the customer terminate or default on the related finance or insurance contract before it is outstanding for a stipulated minimum period of time. We base the chargeback allowance, which was not material to the unaudited condensed consolidated financial statements taken as a whole as of March 31, 2015, on our experience with repayments or defaults on the related finance or insurance contracts.
	We also recognize commissions earned on extended warranty service contracts sold on behalf of third-party insurance companies at the later of customer acceptance of the service contract terms as evidenced by contract execution or recognition of the related boat sale. We are charged back for a portion of these commissions should the customer terminate or default on the service contract prior to its scheduled maturity. We determine the chargeback allowance, which was not material to the unaudited condensed consolidated financial statements taken as a whole as of March 31, 2015, based upon our experience with terminations or defaults on the service contracts.

Inventory Disclosure [Abstract]
Inventories	5	INVENTORIES:
	Inventory costs consist of the amount paid to acquire inventory, net of vendor consideration and purchase discounts, the cost of equipment added, reconditioning costs, and transportation costs relating to acquiring inventory for sale. We state new and used boat, motor, and trailer inventories at the lower of cost, determined on a specific-identification basis, or market. We state parts and accessories at the lower of cost, determined on an average cost basis, or market. We utilize our historical experience, the aging of the inventories, and our consideration of current market trends as the basis for determining a lower of cost or market valuation allowance. As of September 30, 2014 and March 31, 2015, our lower of cost or market valuation allowance for new and used boat, motor, and trailer inventories was $2.2 million and $2.5 million, respectively. If events occur and market conditions change, causing the fair value to fall below carrying value, the lower of cost or market valuation allowance could increase.

Impairment of Long-Lived Assets	6	IMPAIRMENT OF LONG-LIVED ASSETS:
	FASB Accounting Standards Codification 360-10-40, “Property, Plant, and Equipment - Impairment or Disposal of Long-Lived Assets” (“ASC 360-10-40”), requires that long-lived assets, such as property and equipment and purchased intangibles subject to amortization, be reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of the asset is measured by comparison of its carrying amount to undiscounted future net cash flows the asset is expected to generate. If such assets are considered to be impaired, the impairment to be recognized is measured as the amount by which the carrying amount of the asset exceeds its fair market value. Estimates of expected future cash flows represent our best estimate based on currently available information and reasonable and supportable assumptions. Any impairment recognized in accordance with ASC 360-10-40 is permanent and may not be restored. Based upon our most recent analysis, we believe no impairment of long-lived assets existed as of March 31, 2015.

Income Tax Disclosure [Abstract]
Income Taxes	7	INCOME TAXES:
	We account for income taxes in accordance with FASB Accounting Standards Codification 740, “Income Taxes” (“ASC 740”). Under ASC 740, we recognize deferred tax assets and liabilities for the future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. We measure deferred tax assets and liabilities using enacted tax rates expected to apply to taxable income in the years in which we expect those temporary differences to be recovered or settled. We record valuation allowances to reduce our deferred tax assets to the amount expected to be realized by considering all available positive and negative evidence.
	Pursuant to ASC 740, we must consider all positive and negative evidence regarding the realization of deferred tax assets. ASC 740 provides for four possible sources of taxable income to realize deferred tax assets: 1) taxable income in prior carryback years; 2) reversals of existing deferred tax liabilities; 3) tax planning strategies and 4) projected future taxable income. As of March 31, 2015, we have no available taxable income in prior carryback years, reversals of existing deferred tax liabilities or prudent and feasible tax planning strategies. Therefore, the recoverability of our deferred tax assets is dependent upon generating future taxable income. Although as of March 31, 2015, we were no longer in a three year cumulative loss position for financial reporting purposes in our significant jurisdictions, we believe there is sufficient negative evidence concerning our projected future taxable income and, therefore, the realization of our deferred tax assets. Our future taxable income is inherently difficult to project and subject to uncertainty due to many factors including the impact of general economic conditions and the cyclical nature of our operations. Additionally, historically it has been difficult to project our industry’s trends and therefore our results. Based on our analysis of the available evidence we determined that our deferred tax assets needed a full valuation allowance as of March 31, 2015. We will continue to evaluate the need for a valuation allowance. If the full valuation allowance is reversed, we will start recording a tax provision.

ShortTerm_Borrowings

Short-Term Borrowings	6 Months Ended

Debt Disclosure [Abstract]
Short-Term Borrowings	8	SHORT-TERM BORROWINGS:
	In August 2014, we entered into an amendment to our Inventory Financing Agreement (the “Amended Credit Facility”), originally entered into in June 2010, as subsequently amended, with GE Commercial Distribution Finance Corporation. The August 2014 amendment extended the maturity date of the Credit Facility to August 2017, subject to additional extension for two one-year periods, with lender approval. The August 2014 amendment, among other things, modified the amount of borrowing availability and maturity date of the Credit Facility. The Amended Credit Facility provides a floor plan financing commitment of up to $235 million, an increase from the previous limit of $205 million, subject to borrowing base availability resulting from the amount and aging of our inventory.
	The Amended Credit Facility has certain financial covenants as specified in the agreement. The covenants include provisions that our leverage ratio must not exceed 2.75 to 1.0 and that our current ratio must be greater than 1.2 to 1.0. The interest rate for amounts outstanding under the Amended Credit Facility is 345 basis points above the one-month London Inter-Bank Offering Rate (“LIBOR”). There is an unused line fee of ten basis points on the unused portion of the Amended Credit Facility.
	Advances under the Amended Credit Facility are initiated by the acquisition of eligible new and used inventory or are re-advances against eligible new and used inventory that have been partially paid-off. Advances on new inventory will generally mature 1,080 days from the original invoice date. Advances on used inventory will mature 361 days from the date we acquire the used inventory. Each advance is subject to a curtailment schedule, which requires that we pay down the balance of each advance on a periodic basis starting after six months. The curtailment schedule varies based on the type and value of the inventory. The collateral for the Amended Credit Facility is all of our personal property with certain limited exceptions. None of our real estate has been pledged for collateral for the Amended Credit Facility.
	As of March 31, 2015, our indebtedness associated with financing our inventory and working capital needs totaled approximately $165.3 million. As of March 31, 2014 and 2015, the interest rate on the outstanding short-term borrowings was approximately 3.6%. As of March 31, 2015, our additional available borrowings under our Amended Credit Facility were approximately $22.0 million based upon the outstanding borrowing base availability.
	As is common in our industry, we receive interest assistance directly from boat manufacturers, including Brunswick. The interest assistance programs vary by manufacturer, but generally include periods of free financing or reduced interest rate programs. The interest assistance may be paid directly to us or our lender depending on the arrangements the manufacturer has established. We classify interest assistance received from manufacturers as a reduction of inventory cost and related cost of sales as opposed to netting the assistance against our interest expense incurred with our lenders.
	The availability and costs of borrowed funds can adversely affect our ability to obtain adequate boat inventory and the holding costs of that inventory as well as the ability and willingness of our customers to finance boat purchases. As of March 31, 2015, we had no long-term debt. However, we rely on our Amended Credit Facility to purchase our inventory of boats. The aging of our inventory limits our borrowing capacity as defined curtailments reduce the allowable advance rate as our inventory ages. Our access to funds under our Amended Credit Facility also depends upon the ability of our lenders to meet their funding commitments, particularly if they experience shortages of capital or experience excessive volumes of borrowing requests from others during a short period of time. Unfavorable economic conditions, weak consumer spending, turmoil in the credit markets, and lender difficulties, among other potential reasons, could interfere with our ability to utilize our Amended Credit Facility to fund our operations. Any inability to utilize our Amended Credit Facility could require us to seek other sources of funding to repay amounts outstanding under the credit agreements or replace or supplement our credit agreements, which may not be possible at all or under commercially reasonable terms.
	Similarly, decreases in the availability of credit and increases in the cost of credit adversely affect the ability of our customers to purchase boats from us and thereby adversely affect our ability to sell our products and impact the profitability of our finance and insurance activities.

Stock-Based Compensation	9	STOCK-BASED COMPENSATION:
	We account for our stock-based compensation plans following the provisions of FASB Accounting Standards Codification 718, “Compensation — Stock Compensation” (“ASC 718”). In accordance with ASC 718, we use the Black-Scholes valuation model for valuing all stock-based compensation and shares purchased under our Employee Stock Purchase Plan. We measure compensation for restricted stock awards and restricted stock units at fair value on the grant date based on the number of shares expected to vest and the quoted market price of our common stock. For restricted stock units with market conditions, we utilize a Monte Carlo simulation embedded in a lattice model to determine the fair value. We recognize compensation cost for all awards in operations, net of estimated forfeitures, on a straight-line basis over the requisite service period for each separately vesting portion of the award.
	During the six months ended March 31, 2014 and 2015, we recognized stock-based compensation expense of approximately $1.7 million and $1.6 million, respectively, in selling, general, and administrative expenses in the unaudited condensed consolidated statements of operations. There were no tax benefits realized for tax deductions from option exercises for the six months ended March 31, 2014 and 2015.
	Cash received from option exercises under all share-based compensation arrangements for the six months ended March 31, 2014 and 2015, was approximately $3.1 million and $3.0 million, respectively. We currently expect to satisfy share-based awards with registered shares available to be issued.

During January 2011, our stockholders approved a proposal to authorize our 2011 Plan, which replaced our 2007 Incentive Compensation Plan (“2007 Plan”). Our 2011 Plan provides for the grant of stock options, stock appreciation rights, restricted stock, stock units, bonus stock, dividend equivalents, other stock related awards, and performance awards (collectively “awards”), that may be settled in cash, stock, or other property. Our 2011 Plan is designed to attract, motivate, retain, and reward our executives, employees, officers, directors, and independent contractors by providing such persons with annual and long-term performance incentives to expend their maximum efforts in the creation of stockholder value. Subsequent to the February 2013 amendment described above, the total number of shares of our common stock that may be subject to awards under the 2011 Plan is equal to 2,000,000 shares, plus: (i) any shares available for issuance and not subject to an award under the 2007 Plan, which was 200,456 shares at the time of approval of the 2011 Plan; (ii) the number of shares with respect to which awards granted under the 2011 Plan and the 2007 Plan terminate without the issuance of the shares or where the shares are forfeited or repurchased; (iii) with respect to awards granted under the 2011 Plan and the 2007 Plan, the number of shares that are not issued as a result of the award being settled for cash or otherwise not issued in connection with the exercise or payment of the award; and (iv) the number of shares that are surrendered or withheld in payment of the exercise price of any award or any tax withholding requirements in connection with any award granted under the 2011 Plan or the 2007 Plan. The 2011 Plan terminates in January 2021, and awards may be granted at any time during the life of the 2011 Plan. The date on which awards vest are determined by the Board of Directors or the Plan Administrator. The Board of Directors has appointed the Compensation Committee as the Plan Administrator. The exercise prices of options are determined by the Board of Directors or the Plan Administrator and are at least equal to the fair market value of shares of common stock on the date of grant. The term of options under the 2011 Plan may not exceed ten years. The options granted have varying vesting periods. To date, we have not settled or been under any obligation to settle any awards in cash.
	The following table summarizes option activity from September 30, 2014 through March 31, 2015:

	Exercisable as of March 31, 2015						1,165,418		$	18,837		$	11.3			5.4
	The weighted average grant date fair value of options granted during the six months ended March 31, 2014 and 2015 was $6.23 and $5.79, respectively. The total intrinsic value of options exercised during the six months ended March 31, 2014 and 2015 was $3.1 million and $7.2 million, respectively.
	As of March 31, 2014 and 2015, there was approximately $2.8 million and $2.9 million, respectively, of unrecognized compensation costs related to non-vested options that are expected to be recognized over a weighted average period of 2.4 years and 2.0 years, respectively. The total fair value of options vested during the six months ended March 31, 2014 and 2015 was approximately $1.3 million and $444,000, respectively.
	We used the Black-Scholes model to estimate the fair value of options granted. The expected term of options granted is derived from the output of the option pricing model and represents the period of time that options granted are expected to be outstanding. Volatility is based on the historical volatility of our common stock. The risk-free rate for periods within the contractual term of the options is based on the U.S. Treasury yield curve in effect at the time of grant.
	The following are the weighted average assumptions used for each respective period:

Employee Stock Purchase Plan	11	EMPLOYEE STOCK PURCHASE PLAN:
	During February 2012, our stockholders approved a proposal to amend our 2008 Employee Stock Purchase Plan (“Stock Purchase Plan”) to increase the number of shares available under that plan by 500,000 shares. The Stock Purchase Plan as amended provides for up to 1,000,000 shares of common stock to be available for purchase by our regular employees who have completed at least one year of continuous service. In addition, there were 52,837 shares of common stock available under our 1998 Employee Stock Purchase Plan, which have been made available for issuance under our Stock Purchase Plan. The Stock Purchase Plan provides for implementation of up to 10 annual offerings beginning on the first day of October starting in 2008, with each offering terminating on September 30 of the following year. Each annual offering may be divided into two six-month offerings. For each offering, the purchase price per share will be the lower of: (i) 85% of the closing price of the common stock on the first day of the offering or (ii) 85% of the closing price of the common stock on the last day of the offering. The purchase price is paid through periodic payroll deductions not to exceed 10% of the participant’s earnings during each offering period. However, no participant may purchase more than $25,000 worth of common stock annually.
	We used the Black-Scholes model to estimate the fair value of options granted to purchase shares issued pursuant to the Stock Purchase Plan. The expected term of options granted is derived from the output of the option pricing model and represents the period of time that options granted are expected to be outstanding. Volatility is based on the historical volatility of our common stock. The risk-free rate for periods within the contractual term of the options is based on the U.S. Treasury yield curve in effect at the time of grant.
	The following are the weighted average assumptions used for each respective period:
			Three Months Ended						Six Months Ended

Restricted Stock Awards	12	RESTRICTED STOCK AWARDS:
	We have granted non-vested (restricted) stock awards (“restricted stock”) and restricted stock units (“RSUs”) to certain key employees pursuant to the 2011 Plan and the 2007 Plan. The restricted stock awards have varying vesting periods, but generally become fully vested between two and four years after the grant date, depending on the specific award. We accounted for the restricted stock awards granted using the measurement and recognition provisions of ASC 718. Accordingly, the fair value of the restricted stock awards is measured on the grant date and recognized in earnings over the requisite service period for each separately vesting portion of the award.
	The following table summarizes restricted stock award activity from September 30, 2014 through March 31, 2015:
			Shares			Weighted
						Average Grant
						Date Fair Value
	Non-vested balance as of September 30, 2014			3,340		$	6.1

	Non-vested balance as of March 31, 2015			111,000		$	19.23
	As of March 31, 2015, we had approximately $2.1 million of total unrecognized compensation cost related to non-vested restricted stock awards assuming applicable performance conditions are met. We expect to recognize that cost over a weighted average period of 2.6 years.

	For the three months ended March 31, 2015, there were 1,361,973 weighted average shares of options outstanding, respectively, that were not included in the computation of diluted income per share because the options’ exercise prices were greater than the average market price of our common stock, and therefore, their effect would be anti-dilutive. For the six months ended March 31, 2015, there were 1,472,001 weighted average shares of options outstanding, respectively, that were not included in the computation of diluted income per share because the options’ exercise prices were greater than the average market price of our common stock, and therefore, their effect would be anti-dilutive. For the three months ended March 31, 2014 and the six months ended March 31, 2014 no options or non-vested restricted stock awards were included in the computation of diluted loss per share because we reported a net loss and the effect of their inclusion would be anti-dilutive.

Accounting Policies [Abstract]
Fair Value of Financial Instruments	The carrying amounts of our financial instruments reported on the balance sheet as of March 31, 2015 approximated fair value due either to length to maturity or existence of variable interest rates, which approximate prevailing market rates.
Use of Estimates	The preparation of unaudited condensed consolidated financial statements in conformity with accounting principles generally accepted in the United States requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the unaudited condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting periods. Significant estimates made by us in the accompanying unaudited condensed consolidated financial statements include valuation allowances, valuation of goodwill and intangible assets, valuation of long-lived assets, and valuation of accruals. Actual results could differ from those estimates.
Consolidation	The unaudited condensed consolidated financial statements include our accounts and the accounts of our subsidiaries, all of which are wholly owned. All significant intercompany transactions and accounts have been eliminated.
Revenue Recognition	We recognize revenue from boat, motor, and trailer sales, and parts and service operations at the time the boat, motor, trailer, or part is delivered to or accepted by the customer or the service is completed. We recognize deferred revenue from service operations and slip and storage services on a straight-line basis over the term of the contract or when service is completed. We recognize commissions earned from a brokerage sale at the time the related brokerage transaction closes. We recognize commissions earned by us for placing notes with financial institutions in connection with customer boat financing when we recognize the related boat sales. We recognize marketing fees earned on credit, life, accident, disability, gap, and hull insurance products sold by third-party insurance companies at the later of customer acceptance of the insurance product as evidenced by contract execution or when the related boat sale is recognized. Pursuant to negotiated agreements with financial and insurance institutions, we are charged back for a portion of these fees should the customer terminate or default on the related finance or insurance contract before it is outstanding for a stipulated minimum period of time. We base the chargeback allowance, which was not material to the unaudited condensed consolidated financial statements taken as a whole as of March 31, 2015, on our experience with repayments or defaults on the related finance or insurance contracts.
	We also recognize commissions earned on extended warranty service contracts sold on behalf of third-party insurance companies at the later of customer acceptance of the service contract terms as evidenced by contract execution or recognition of the related boat sale. We are charged back for a portion of these commissions should the customer terminate or default on the service contract prior to its scheduled maturity. We determine the chargeback allowance, which was not material to the unaudited condensed consolidated financial statements taken as a whole as of March 31, 2015, based upon our experience with terminations or defaults on the service contracts.
Inventories	Inventory costs consist of the amount paid to acquire inventory, net of vendor consideration and purchase discounts, the cost of equipment added, reconditioning costs, and transportation costs relating to acquiring inventory for sale. We state new and used boat, motor, and trailer inventories at the lower of cost, determined on a specific-identification basis, or market. We state parts and accessories at the lower of cost, determined on an average cost basis, or market. We utilize our historical experience, the aging of the inventories, and our consideration of current market trends as the basis for determining a lower of cost or market valuation allowance. As of September 30, 2014 and March 31, 2015, our lower of cost or market valuation allowance for new and used boat, motor, and trailer inventories was $2.2 million and $2.5 million, respectively. If events occur and market conditions change, causing the fair value to fall below carrying value, the lower of cost or market valuation allowance could increase.
Property Plant and Equipment Impairment or Disposal of Long Lived Assets	FASB Accounting Standards Codification 360-10-40, “Property, Plant, and Equipment - Impairment or Disposal of Long-Lived Assets” (“ASC 360-10-40”), requires that long-lived assets, such as property and equipment and purchased intangibles subject to amortization, be reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of the asset is measured by comparison of its carrying amount to undiscounted future net cash flows the asset is expected to generate. If such assets are considered to be impaired, the impairment to be recognized is measured as the amount by which the carrying amount of the asset exceeds its fair market value. Estimates of expected future cash flows represent our best estimate based on currently available information and reasonable and supportable assumptions. Any impairment recognized in accordance with ASC 360-10-40 is permanent and may not be restored. Based upon our most recent analysis, we believe no impairment of long-lived assets existed as of March 31, 2015.
Income Taxes	We account for income taxes in accordance with FASB Accounting Standards Codification 740, “Income Taxes” (“ASC 740”). Under ASC 740, we recognize deferred tax assets and liabilities for the future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. We measure deferred tax assets and liabilities using enacted tax rates expected to apply to taxable income in the years in which we expect those temporary differences to be recovered or settled. We record valuation allowances to reduce our deferred tax assets to the amount expected to be realized by considering all available positive and negative evidence.
	Pursuant to ASC 740, we must consider all positive and negative evidence regarding the realization of deferred tax assets. ASC 740 provides for four possible sources of taxable income to realize deferred tax assets: 1) taxable income in prior carryback years; 2) reversals of existing deferred tax liabilities; 3) tax planning strategies and 4) projected future taxable income. As of March 31, 2015, we have no available taxable income in prior carryback years, reversals of existing deferred tax liabilities or prudent and feasible tax planning strategies. Therefore, the recoverability of our deferred tax assets is dependent upon generating future taxable income. Although as of March 31, 2015, we were no longer in a three year cumulative loss position for financial reporting purposes in our significant jurisdictions, we believe there is sufficient negative evidence concerning our projected future taxable income and, therefore, the realization of our deferred tax assets. Our future taxable income is inherently difficult to project and subject to uncertainty due to many factors including the impact of general economic conditions and the cyclical nature of our operations. Additionally, historically it has been difficult to project our industry’s trends and therefore our results. Based on our analysis of the available evidence we determined that our deferred tax assets needed a full valuation allowance as of March 31, 2015. We will continue to evaluate the need for a valuation allowance. If the full valuation allowance is reversed, we will start recording a tax provision.
Stock Compensation	We account for our stock-based compensation plans following the provisions of FASB Accounting Standards Codification 718, “Compensation — Stock Compensation” (“ASC 718”). In accordance with ASC 718, we use the Black-Scholes valuation model for valuing all stock-based compensation and shares purchased under our Employee Stock Purchase Plan. We measure compensation for restricted stock awards and restricted stock units at fair value on the grant date based on the number of shares expected to vest and the quoted market price of our common stock. For restricted stock units with market conditions, we utilize a Monte Carlo simulation embedded in a lattice model to determine the fair value. We recognize compensation cost for all awards in operations, net of estimated forfeitures, on a straight-line basis over the requisite service period for each separately vesting portion of the award.
