Accounting Policies [Abstract]
Significant Accounting Policies	2. Significant Accounting Policies (a) Principles of Consolidation (b) Use of Estimates (c) Accounting for Revenue, Voyage Expenses and Operating Expenses : Revenue is generated from time or voyage charter contracts. Time charters contracts A time charter is a contract for the use of a vessel for a specific period of time and a specified daily charter hire rate, which is generally payable in advance. A time charter generally provides typical warranties and owner protective restrictions. A time charter begins when the vessel is delivered to the charterer and ends when the vessel is redelivered back to its owner. The time charter contracts are considered operating leases because (i) the vessel is an identifiable asset (ii) the owner of the vessel does not have substantive substitution rights and (iii) the charterer has the right to control the use of the vessel during the term of the contract and derives the economic benefits from such use. Revenues from time charters are recognized ratably on a straight-line basis over the period of the respective charter. Under time charter agreements, all voyage expenses, except commissions are assumed by the charterer. Operating costs incurred for running the vessel such as crew costs, vessel insurance, repairs and maintenance and lubricants are paid by the Partnership under time charter agreements. Voyage charters contracts A voyage charter is a contract in which the vessel owner undertakes to transport a specific amount and type of cargo on a load port-to-discharge port basis, subject to various cargo handling terms. The Partnership accounts for a voyage charter when all the following criteria are met: (1) the parties to the contract have approved the contract in the form of a written charter agreement and are committed to perform their respective obligations, (2) the Partnership can identify each party’s rights regarding the services to be transferred, (3) the Partnership can identify the payment terms for the services to be transferred, (4) the charter agreement has commercial substance (that is, the risk, timing, or amount of the Partnership’s future cash flows is expected to change as a result of the contract) and (5) it is probable that the Partnership will collect substantially all of the consideration to which it will be entitled in exchange for the services that will be transferred to the charterer. The Partnership determined that its voyage charters consist of a single performance obligation which is met evenly as the voyage progresses and begins to be satisfied once the vessel is ready to load the cargo. The voyage charter party agreement generally has a demurrage/dispatch clause according to which in the case of demurrage, the charterer reimburses the vessel owner for any potential delays exceeding the allowed lay time as per the charter party clause at the ports visited which is recorded as demurrage revenue. In the case of dispatch, the owner reimburses the charterer for the earlier discharging of the cargo from the agreed time. Demurrage/despatch revenues are recognized starting from the point that is determined that the amount can be estimated, and its collection/payment is probable and on a straight-line basis until the end of the voyage. Revenues from voyage charters are recognized on a straight-line basis over the voyage duration which commences once the vessel is ready to load the cargo and terminates upon the completion of the discharge of the cargo. Under Accounting Standards Codification (“ASC”) 606, receivables represent an entity’s unconditional right to consideration, whether billed or unbilled. In voyage charters, vessel operating expenses and voyage expenses are paid for by the Partnership. The voyage charters are considered service contracts which fall under the provisions of ASC 606, because the Partnership retains control over the operations of the vessels, such as the routes taken or the vessels’ speed. Payment terms under voyage charters are disclosed in the relevant voyage charter agreements and generally have standard payment terms of 90% to 95% of the freight which is paid within three days after the completion of the vessel’s loading. 2. Significant Accounting Policies – Continued (c) Accounting for Revenue, Voyage Expenses and Operating Expenses - Continued: Vessel voyage expenses are direct expenses to voyage revenues and primarily consist of brokerage commissions, port expenses, canal dues and bunkers. Brokerage commissions are paid to shipbrokers for their time and efforts for negotiating and arranging charter party agreements on behalf of the Partnership and are expensed over the related charter period. All other voyage expenses are expensed as incurred, except for expenses during the ballast portion of the voyage (period between the contract date and the date of the vessel’s arrival to the load port). Any expenses incurred during the ballast portion of the voyage such as bunker expenses, canal tolls and port expenses are deferred and are recognized on a straight-line basis, in voyage expenses, over the voyage duration as the Partnership satisfies the performance obligations under the contract provided these costs are (1) incurred to fulfill a contract that we can specifically identify, (2) able to generate or enhance resources of the company that will be used to satisfy performance of the terms of the contract, and (3) expected to be recovered from the charterer. These costs are considered ‘contract fulfillment costs’ and are included in ‘prepayments and other assets’ in the consolidated balance sheets. Vessel operating expenses presented in the consolidated financial statements mainly consist of crew, repairs and maintenance, insurance, stores, spares, lubricants, other operating expenses and management fees payable to the Partnership’s managers. Vessel operating expenses are expensed as incurred. (d) Foreign Currency Transactions (e) Cash and Cash Equivalents three 192,422 144,635 (f) Restricted cash 11,721 10,213 (g) Trade Accounts Receivable, net 3,117 2,102 920 0 (h) Inventories 5,553 6,817 (i) Vessels Held for Sale Vessels classified as held for sale are measured at the lower of their carrying amount or fair value less costs to sell. These vessels are not depreciated once they meet the criteria to be classified as held for sale. If a plan to sell a vessel is cancelled, the Partnership reclassifies the vessel as held for use and re-measures it at the lower of (i) its carrying amount before the vessel was classified as held for sale, adjusted for any depreciation expense that would have been recognized if the vessel had been continuously classified as held and used and (ii) its fair value at the date of the subsequent decision not to sell. On December 15, 2023, the Partnership agreed to sell to an unaffiliated party the M/V Long Beach Express (Notes 5, 6). On that date the Partnership considered that the M/V Long Beach Express met the criteria to be classified as held for sale. 2. Significant Accounting Policies – Continued (j) Fixed Assets 0.2 25 35 (k) Impairment of Vessels The Partnership has performed an undiscounted cash flow test as of December 31, 2023, and 2022, determining undiscounted projected net operating cash flows for each vessel for which an indication for impairment was present and compared them to the carrying amount of the vessels, and any related intangible assets and liabilities. In developing estimates of future cash flows, the Partnership made assumptions about future charter rates, utilization rates, vessel operating expenses, future dry-docking costs, the estimated remaining useful life of the vessels and their estimated residual value. These assumptions are based on historical trends as well as future expectations that are in line with the Partnership’s historical performance and expectations for the vessels’ utilization under the current deployment strategy. Based on these assumptions, the Partnership determined that the vessels held for use and their related intangible assets and liabilities were not impaired as of December 31, 2023 and 2022. (l) Deferred charges, net : Deferred charges, net are comprised mainly of dry-docking costs. The Partnership’s vessels are required to be dry-docked every 30 to 60 months for major repairs and maintenance that cannot be performed while the vessels are under operation. The Partnership has adopted the deferral method of accounting for dry-docking activities whereby costs incurred are deferred and amortized on a straight-line basis over the period until the next scheduled dry-docking activity. As of December 31, 2023, and 2022 the Partnership had deferred charges, net of $ 4,714 and $ 289 , respectively.

The fair value of the time charters attached to the vessels representing the difference between the time charters rates at which the vessels were fixed and the market rates for comparable charters as determined by reference to market data on the acquisition dates were recorded as “Above market acquired charters” under other non-current assets or “Below market acquired charters” under long-term liabilities in the consolidated balance sheet as of the acquisition dates respectively. The fair values of the time charters attached were determined using Level 2 inputs being market values on the acquisition dates (Note 9). On December 15, 2023, the Partnership agreed to sell to an unaffiliated party the M/V Long Beach Express along with its time charter attached (Note 5). As a result, the partnership classified the unamortized below market acquired charter of the M/V Long Beach Express on that date as Below market acquired charter associated with vessel held for sale under current liabilities in the consolidated balance sheets. During the year ended December 31, 2022, the Partnership acquired the M/V Manzanillo Express with time charter attached to the vessel, with time charter daily rate being at market rate for equivalent time charter prevailing at the time of acquisition (Note 5A). As a result, no above / below market acquired charter was recognized. Above and below market acquired time charters are amortized or accreted using the straight-line method over the remaining period of the time charters acquired as a reduction or addition to time charter revenues. For the years ended December 31, 2023 and 2022 such amortization to time charter revenues for the above market acquired time charters amounted to $ 16,158 16,285 15,267 4,275 The following table presents an analysis of above / below market acquired charters: Above / Below market acquired time charters (Table) Above market acquired charters Below market acquired charters Carrying amount as at January 1, 2022 $ 48,605 $ (14,643) (Amortization) / accretion (16,285) 4,275 Carrying amount as at December 31, 2022 $ 32,320 $ (10,368) Additions 67,227 (94,889) (Amortization) / accretion (16,158) 15,267 Transfer to below market acquired charter associated with vessel held for sale — 1,447 Carrying amount as at December 31, 2023 $ 83,389 $ (88,543) 6.

Derivative Instruments	8. Derivative Instruments In connection with the issuance of the 2022 Bonds and the 2021 Bonds (Note 7), the Partnership entered into certain cross-currency swap agreements to manage the related foreign currency exchange risk by effectively converting the fixed-rate, Euro-denominated Bonds, including the semi-annual interest payments for the period from July 26, 2022 to July 26, 2029 and from October 21, 2021 to October 21, 2025, respectively to fixed-rate, U.S. Dollar-denominated debt. The economic effect of the swap agreements is to eliminate the uncertainty of the cash flows in U.S. Dollars associated with the issuance of the 2022 Bonds and the 2021 Bonds by fixing the principal amount of the 2022 Bonds and the 2021 Bonds, with a fixed annual interest rate. The cross-currency swap agreement related to the 2022 Bonds was designated as an accounting hedge. Derivative instruments not designated as hedges are not speculative and are used to manage the Partnership’s exposure to identified risks but do not meet the strict hedge accounting requirements and/or the Partnership has not elected to apply hedge accounting. Changes in the fair value of derivatives not designated in hedging relationships are recorded directly in the consolidated statements of comprehensive income. Changes in the fair value of derivatives designated as accounting hedges are recorded in the consolidated statements of other comprehensive income (effective portion), until the hedged item is recognized in the consolidated statements of comprehensive income.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Financial Instruments	9. Financial Instruments (a) Fair value of financial instruments Cash and cash equivalents, restricted cash and other assets and liabilities. The carrying value of cash and cash equivalents and restricted cash, are considered Level 1 items as they represent liquid assets with short-term maturities, trade receivables, amounts due to related parties, trade accounts payable and accrued liabilities approximate their fair value. Long-term debt The fair value of variable rate long-term debt (Note 7) approximates the recorded value, due to its variable interest being based on the SOFR rates (on the LIBOR and the SOFR, for 2022) and due to the fact that the lenders have the ability to pass on their funding cost to the Partnership under certain circumstances, which reflects their current assessed risk. We believe the terms of our loans are similar to those that could be procured as of December 31, 2023. SOFR rates are observable at commonly quoted intervals for the full term of the loans and hence bank loans are considered Level 2 items in accordance with the fair value hierarchy. The fair value of the fixed rate long-term debt (Note 7 ((i), (xv) and (xvi)) as of December 31, 2023, was approximately $ 147,210 169,115 The 2022 Bonds and the 2021 Bonds (Note 7 ((xix) and (xx))) have a fixed rate, and their estimated fair values as of December 31, 2023, were determined through Level 1 inputs of the fair value hierarchy (quoted price under the ticker symbols CPLPB1 and CPLPB2 on Athens Stock Exchange) and were approximately $ 215,071 276,640 Derivative instruments As of December 31, 2023: Financial Instruments - Fair value measurements on a recurring basis (Table) Items Measured at Fair Value on a recurring Basis - Fair Value Measurements Recurring Measurements: December 31, 2023 Quoted prices in active markets for identical assets (Level 1) Significant other Observable inputs (Level 2) Unobservable Inputs (Level 3) Cross Currency SWAP (100,000) – asset position $ 6,636 $ – $ 6,636 $ – Cross Currency SWAP (120,000) – liability position (5,758) – (5,758) – Cross Currency SWAP (30,000) – liability position (1,422) – (1,422) – Total $ (544) $ – $ (544) $ – As of December 31, 2022: Items Measured at Fair Value on a recurring Basis - Fair Value Measurements Recurring Measurements: December 31, 2022 Quoted prices in active markets for identical assets (Level 1) Significant other Observable inputs (Level 2) Unobservable Inputs (Level 3) Cross Currency SWAP (100,000) - liability position $ (10,068) $ – $ (10,068) $ – Cross Currency SWAP (120,000) – liability position (2,641) – (2,641) – Cross Currency SWAP (30,000) – liability position (816) – (816 – Total $ (13,525) $ – $ (13,525) $ – The fair value (Level 2) of cross-currency swap derivative agreements is the present value of the estimated future cash flows that we would receive or pay to terminate the agreements at the balance sheet date, taking into account, as applicable, current interest rates, foreign exchange rates and the credit worthiness of both us and the derivative counterparty. This line item is presented in “Derivative asset” and “Derivative liabilities” in the consolidated balance sheets. There were no Level 3 items. (b) Concentration of credit risk Financial instruments which potentially subject the Partnership to significant concentrations of credit risk consist principally of cash and cash equivalents and trade accounts receivable, net. The Partnership places its cash and cash equivalents, consisting mostly of deposits, with a limited number of creditworthy financial institutions rated by qualified rating agencies. Most of the Partnership’s revenues were derived from a few charterers.

Income Taxes	12. Income Taxes Under the laws of the Marshall Islands and Liberia, the countries in which the vessel-owning subsidiaries were incorporated, these companies are not subject to tax on international shipping income. However, they are subject to registration and tonnage taxes in the country in which the vessels are registered and managed from, and such taxes have been included in “Vessel operating expenses” in the consolidated statements of comprehensive income. Pursuant to Section 883 of the United States Internal Revenue Code (the “Code”) and the regulations thereunder, a foreign corporation engaged in the international operation of ships is generally exempt from U.S. federal income tax on its U.S.-source shipping income if the foreign corporation meets both of the following requirements: (a) the foreign corporation is organized in a foreign country that grants an “equivalent exemption” to corporations organized in the United States for the types of shipping income (e.g., voyage and time charter) earned by the foreign corporation and (b) more than 50% of the voting power and value of the foreign corporation’s stock is “primarily and regularly traded on an established securities market” in the United States and certain other requirements are satisfied (the “Publicly-Traded Test”). Each of the jurisdictions where the Partnership’s vessel-owning subsidiaries are incorporated grants an “equivalent exemption” to United States corporations with respect to each type of shipping income earned by the Partnership’s vessel-owning subsidiaries. Additionally, our units are only traded on the Nasdaq Global Market, which is considered to be an established securities market. The Partnership has satisfied the Publicly-Traded Test for the years ended December 31, 2023, 2022 and 2021 and the vessel-owning subsidiaries are exempt from United States federal income taxation with respect to U.S.-source shipping income. CPLP PLC is incorporated in Cyprus and does not conduct any substantive operations of its own. No provision for Cyprus income tax has been made in the financial statements as CPLP PLC had no assessable income for the years ended December 31, 2023 and 2022 and the period from August 14, 2021 (inception) to December 31, 2021. 0

Equity [Abstract]
Partners’ Capital	13. Partners’ Capital General: Definition of Available Cash: • less the amount of cash reserves established by our board of directors to: • provide for the proper conduct of the Partnership’s business (including reserves for future capital expenditures and for our anticipated credit needs); • comply with applicable law, any of the Partnership’s debt instruments, or other agreements; or • provide funds for distributions to the Partnership’s unit holders and to the general partner for any one or more of the next four quarters; • plus all cash on hand on the date of determination of available cash for the quarter resulting from working capital borrowings made after the end of the quarter. Working capital borrowings are generally borrowings that are made under our credit agreements and in all cases are used solely for working capital purposes or to pay distributions to partners subject to certain exceptions set forth in the Partnership Agreement. General Partner Interest and IDRs: 0.63 % interest in the Partnership (excluding treasury units) and holds the IDRs. In accordance with Section 5.2(b) of the Partnership Agreement, upon the issuance of additional units by the Partnership, the general partner may elect to make a contribution to the Partnership to maintain its general partner interest. IDRs represent the right to receive an increasing percentage of quarterly distributions of available cash from operating surplus after the minimum quarterly distribution and the target distribution levels have been achieved. According to the Partnership Agreement, as amended in 2014, the following table illustrates the percentage allocations of the additional available cash from operating surplus among the unit holders and general partner up to the various target distribution levels. The amounts set forth under “Marginal Percentage Interest in Distributions” are the percentage interests of the unit holders and general partner in any available cash from operating surplus that is being distributed up to and including the corresponding amount in the column “Total Quarterly Distribution Target Amount per Unit,” until available cash from operating surplus the Partnership distributes reaches the next target distribution level, if any.

Earnings Per Share [Abstract]
Net Income Per Unit	15. Net Income Per Unit The general partner’s and common unit holders’ interests in net income are calculated as if all net income for periods after April 4, 2007, were distributed according to the terms of the Partnership Agreement, regardless of whether those earnings would or could be distributed. The Partnership Agreement does not provide for the distribution of net income; rather, it provides for the distribution of available cash (Note 13), which is a contractually defined term that generally means all cash on hand at the end of each quarter after establishment of cash reserves determined by the Partnership’s board of directors to provide for the proper resources for the Partnership’s business. Unlike available cash, net income is affected by non-cash items. The Partnership follows the guidance relating to the Application of the Two-Class Method and its application to Master Limited Partnerships, which considers whether the incentive distributions of a master limited partnership represent a participating security when considered in the calculation of earnings per unit under the Two-Class Method. The Partnership also considers whether the Partnership Agreement contains any contractual limitations concerning distributions to the IDRs that would impact the amount of earnings to allocate to the IDRs for each reporting period. Under the Partnership Agreement, the holder of the IDRs in the Partnership, which is currently CGP, assuming that there are no cumulative arrearages on common unit distributions, has the right to receive an increasing percentage of cash distributions (Note 13). For the year ended December 31, 2023, the Partnership excluded the effect of 495,867 non-vested unit awards, from which 247,933 vested on December 31, 2023, in calculating dilutive EPU for its common unitholders as they were anti-dilutive. For the year ended December 31, 2022, the Partnership excluded the effect of 745,769 249,902 For the year ended December 31, 2021, the Partnership excluded the effect of 412,916 15. Net Income Per Unit - Continued The non-vested units are participating securities because they received distributions from the Partnership and these distributions did not have to be returned to the Partnership if the non-vested units were forfeited by the grantee. The Partnership’s net income for the years ended December 31, 2023, 2022 and 2021 did not exceed the First Target Distribution Level, and as a result, the assumed distribution of net income did not result in the use of increasing percentages to calculate CGP’s interest in net income. The two-class method used to calculate EPU from continuing operations is as follows: Net Income Per Unit - Basic and Diluted (Table) BASIC AND DILUTED 2023 2022 2021 Numerators Partnership’s net income $ 47,208 $ 125,421 $ 98,178 Less: General Partner’s interest in Partnership’s net income 680 2,157 1,790 Partnership’s net income allocable to unvested units 929 3,662 2,053 Common unit holders’ interest in Partnership’s net income $ 45,599 $ 119,602 $ 94,335 Denominators Weighted average number of common units outstanding, basic and diluted 21,182,471 19,325,030 18,342,413 Net income per common unit: Basic and Diluted (in United States Dollars) $ 2.15 $ 6.19 $ 5.14

Commitments and Contingencies	16. Commitments and Contingencies Contingencies Various claims, suits, and complaints, including those involving government regulations and product liability, arise in the ordinary course of the shipping business. In addition, losses may arise from disputes with charterers, agents, insurance and other claims with suppliers relating to the operations of the Partnership’s vessels. The Partnership accrues the cost of environmental liabilities when management becomes aware that a liability is probable and is able to reasonably estimate the probable exposure. An estimated loss from a contingency should be accrued by a charge to expense and a liability recorded only if all of the following conditions are met: • Information available prior to the issuance of the financial statement indicates that it is probable that a liability has been incurred at the date of the financial statements. • The amount of the loss can be reasonably estimated. Currently, the Partnership is not aware of any such claims or contingent liabilities which should be disclosed or for which a provision should be established in the consolidated financial statements. 16.

Accounting Policies [Abstract]
Principles of Consolidation	(a) Principles of Consolidation
Use of Estimates	(b) Use of Estimates
Accounting for Revenue, Voyage Expenses and Operating Expenses	(c) Accounting for Revenue, Voyage Expenses and Operating Expenses : Revenue is generated from time or voyage charter contracts. Time charters contracts A time charter is a contract for the use of a vessel for a specific period of time and a specified daily charter hire rate, which is generally payable in advance. A time charter generally provides typical warranties and owner protective restrictions. A time charter begins when the vessel is delivered to the charterer and ends when the vessel is redelivered back to its owner. The time charter contracts are considered operating leases because (i) the vessel is an identifiable asset (ii) the owner of the vessel does not have substantive substitution rights and (iii) the charterer has the right to control the use of the vessel during the term of the contract and derives the economic benefits from such use. Revenues from time charters are recognized ratably on a straight-line basis over the period of the respective charter. Under time charter agreements, all voyage expenses, except commissions are assumed by the charterer. Operating costs incurred for running the vessel such as crew costs, vessel insurance, repairs and maintenance and lubricants are paid by the Partnership under time charter agreements. Voyage charters contracts A voyage charter is a contract in which the vessel owner undertakes to transport a specific amount and type of cargo on a load port-to-discharge port basis, subject to various cargo handling terms. The Partnership accounts for a voyage charter when all the following criteria are met: (1) the parties to the contract have approved the contract in the form of a written charter agreement and are committed to perform their respective obligations, (2) the Partnership can identify each party’s rights regarding the services to be transferred, (3) the Partnership can identify the payment terms for the services to be transferred, (4) the charter agreement has commercial substance (that is, the risk, timing, or amount of the Partnership’s future cash flows is expected to change as a result of the contract) and (5) it is probable that the Partnership will collect substantially all of the consideration to which it will be entitled in exchange for the services that will be transferred to the charterer. The Partnership determined that its voyage charters consist of a single performance obligation which is met evenly as the voyage progresses and begins to be satisfied once the vessel is ready to load the cargo. The voyage charter party agreement generally has a demurrage/dispatch clause according to which in the case of demurrage, the charterer reimburses the vessel owner for any potential delays exceeding the allowed lay time as per the charter party clause at the ports visited which is recorded as demurrage revenue. In the case of dispatch, the owner reimburses the charterer for the earlier discharging of the cargo from the agreed time. Demurrage/despatch revenues are recognized starting from the point that is determined that the amount can be estimated, and its collection/payment is probable and on a straight-line basis until the end of the voyage. Revenues from voyage charters are recognized on a straight-line basis over the voyage duration which commences once the vessel is ready to load the cargo and terminates upon the completion of the discharge of the cargo. Under Accounting Standards Codification (“ASC”) 606, receivables represent an entity’s unconditional right to consideration, whether billed or unbilled. In voyage charters, vessel operating expenses and voyage expenses are paid for by the Partnership. The voyage charters are considered service contracts which fall under the provisions of ASC 606, because the Partnership retains control over the operations of the vessels, such as the routes taken or the vessels’ speed. Payment terms under voyage charters are disclosed in the relevant voyage charter agreements and generally have standard payment terms of 90% to 95% of the freight which is paid within three days after the completion of the vessel’s loading. 2. Significant Accounting Policies – Continued (c) Accounting for Revenue, Voyage Expenses and Operating Expenses - Continued: Vessel voyage expenses are direct expenses to voyage revenues and primarily consist of brokerage commissions, port expenses, canal dues and bunkers. Brokerage commissions are paid to shipbrokers for their time and efforts for negotiating and arranging charter party agreements on behalf of the Partnership and are expensed over the related charter period. All other voyage expenses are expensed as incurred, except for expenses during the ballast portion of the voyage (period between the contract date and the date of the vessel’s arrival to the load port). Any expenses incurred during the ballast portion of the voyage such as bunker expenses, canal tolls and port expenses are deferred and are recognized on a straight-line basis, in voyage expenses, over the voyage duration as the Partnership satisfies the performance obligations under the contract provided these costs are (1) incurred to fulfill a contract that we can specifically identify, (2) able to generate or enhance resources of the company that will be used to satisfy performance of the terms of the contract, and (3) expected to be recovered from the charterer. These costs are considered ‘contract fulfillment costs’ and are included in ‘prepayments and other assets’ in the consolidated balance sheets. Vessel operating expenses presented in the consolidated financial statements mainly consist of crew, repairs and maintenance, insurance, stores, spares, lubricants, other operating expenses and management fees payable to the Partnership’s managers. Vessel operating expenses are expensed as incurred.

Vessels Held for Sale	(i) Vessels Held for Sale Vessels classified as held for sale are measured at the lower of their carrying amount or fair value less costs to sell. These vessels are not depreciated once they meet the criteria to be classified as held for sale. If a plan to sell a vessel is cancelled, the Partnership reclassifies the vessel as held for use and re-measures it at the lower of (i) its carrying amount before the vessel was classified as held for sale, adjusted for any depreciation expense that would have been recognized if the vessel had been continuously classified as held and used and (ii) its fair value at the date of the subsequent decision not to sell. On December 15, 2023, the Partnership agreed to sell to an unaffiliated party the M/V Long Beach Express (Notes 5, 6). On that date the Partnership considered that the M/V Long Beach Express met the criteria to be classified as held for sale. 2. Significant Accounting Policies – Continued

Impairment of Vessels	(k) Impairment of Vessels The Partnership has performed an undiscounted cash flow test as of December 31, 2023, and 2022, determining undiscounted projected net operating cash flows for each vessel for which an indication for impairment was present and compared them to the carrying amount of the vessels, and any related intangible assets and liabilities. In developing estimates of future cash flows, the Partnership made assumptions about future charter rates, utilization rates, vessel operating expenses, future dry-docking costs, the estimated remaining useful life of the vessels and their estimated residual value. These assumptions are based on historical trends as well as future expectations that are in line with the Partnership’s historical performance and expectations for the vessels’ utilization under the current deployment strategy. Based on these assumptions, the Partnership determined that the vessels held for use and their related intangible assets and liabilities were not impaired as of December 31, 2023 and 2022.
Deferred charges, net	(l) Deferred charges, net : Deferred charges, net are comprised mainly of dry-docking costs. The Partnership’s vessels are required to be dry-docked every 30 to 60 months for major repairs and maintenance that cannot be performed while the vessels are under operation. The Partnership has adopted the deferral method of accounting for dry-docking activities whereby costs incurred are deferred and amortized on a straight-line basis over the period until the next scheduled dry-docking activity. As of December 31, 2023, and 2022 the Partnership had deferred charges, net of $ 4,714 and $ 289 , respectively.
