                 SEACOR HOLDINGS ANNOUNCES THIRD QUARTER RESULTS


Fort Lauderdale, Florida
November 9, 2005

FOR IMMEDIATE RELEASE -- SEACOR Holdings Inc. (NYSE:CKH) announced net earnings
for the third quarter ended September 30, 2005 of $20.5 million, or $0.76 per
diluted share, on operating revenues of $294.9 million. For the nine months
ended September 30, 2005, net earnings were $64.2 million, or $2.81 per diluted
share, on operating revenues of $637.9 million.

For the third quarter ended September 30, 2004, net earnings were $3.4 million,
or $0.18 per diluted share, on operating revenues of $116.5 million. For the
nine months ended September 30, 2004, net earnings were $0.6 million, or $0.03
per diluted share, on operating revenues of $309.9 million.

For the previous quarter ended June 30, 2005, the Company reported net earnings
of $25.1 million, or $1.20 per diluted share, on operating revenues of $177.8
million.

IMPACT OF THE SEABULK ACQUISITION - The third quarter included, for the first
time, the result of Seabulk International, Inc. ("Seabulk"), a company acquired
by SEACOR on July 1, 2005. Seabulk's operating revenues for the quarter totaled
$97.9 million compared to $96.7 million in the previous quarter (prior to its
acquisition by SEACOR). Seabulk's business segments produced operating results
consistent with Seabulk's second quarter.

The Seabulk acquisition was accounted for as a purchase under current accounting
guidelines, which required that the Seabulk assets and liabilities were subject
to fair valuation on the date of acquisition. The preliminary fair value of
Seabulk's vessels resulted in an increase in their book value of $385.7 million,
which coupled with SEACOR's policy regarding asset useful lives, resulted in
additional depreciation expense of $16.4 million over Seabulk's previous
quarter.

During the third quarter, Seabulk's result was impacted by a derivative loss of
$4.1 million, related to an interest rate swap. Consistent with SEACOR's
accounting treatment of other derivative instruments, changes in fair value are
reflected in the statement of operations. Prior to its acquisition, Seabulk had
designated this swap as a hedge.

Seabulk's result for the quarter, including the additional depreciation expense
and the derivative impact, was a net loss of $6.9 million or $0.24 per diluted
share.

PRE-EXISTING SEACOR BUSINESS SEGMENTS - Excluding Seabulk's result, net income
from pre-existing SEACOR business segments was $27.4 million on operating
revenues of $197.0 million, compared to $25.1 million on operating revenues of
$177.8 million in the previous quarter. The improvement in results was primarily
attributed to revenue increases and improved operating margins.

Revenue increases were mainly due to higher demand for all classes of equipment
in Offshore Marine Services and Helicopter Services. Business activity in the
third quarter was generally brisk due to increased drilling in the Gulf of
Mexico and damage assessment and re-construction of offshore installations
following Hurricanes Katrina and Rita. Environmental Services also experienced
increased demand due to remediation work required to address the aftermath of
Hurricanes Katrina and Rita. Inland River Services' activity levels were
slightly reduced due to closing the port of New Orleans and logistics
disruptions associated with hurricanes and low water in the river system.
Improvements in freight rates compensated for reduction in loadings and cargo.


Offshore Marine Services recorded a $4.4 million charge relating to a funding
deficit in a UK multi-company pension fund in which the company is deemed to be
a participating employer. Offshore Marine Services was also affected by
hurricane damage to certain Gulf Coast facilities of its logistics business
resulting in a write-off of certain tangible assets and a goodwill impairment
charge totaling $1.6 million. In all other respects, costs and expenses
generally increased in response to the higher levels of business activity.

Excluding Seabulk's result, operating income for the quarter was $32.3 million,
an increase of $7.7 million over the previous quarter. Operating income improved
in Offshore Marine Services, Helicopter Services and Inland River Services in
response to the improvements in revenues. Environmental Services achieved
improved operating income despite an overall reduction in spill activity.

Excluding Seabulk's result, foreign currency transaction gains for the current
quarter were $2.4 million, compared to gains of $4.4 million in the previous
quarter. Marketable securities transactions resulted in net gains of $10.4
million, compared to gains of $8.5 million in the previous quarter.

SEACOR recognized an impairment charge of $2.7 million, net of tax, with respect
to one of its equity investments.

CAPITAL COMMITMENTS - As of November 9, 2005, capital commitments in respect of
all classes of assets aggregated $563.8 million.

QUARTERLY REPORT FILING - SEACOR was unable to file its Quarterly Report on Form
10-Q for the quarter ended September 30, 2005 on today's due date without
unreasonable effort and expense due to damage caused by Hurricane Wilma.
SEACOR's principal accounting functions are based in Ft. Lauderdale, Florida.
From October 24, 2005 through November 1, 2005, due to damage caused by
Hurricane Wilma, its Ft. Lauderdale office was effectively closed, with no
water, limited generator power, limited fuel and limited access by office
personnel, delaying SEACOR's ability to compile the required information and
complete the preparation of its Quarterly Report on Form 10-Q for the quarter
ended September 30, 2005. SEACOR expects to file its Form 10-Q on Monday,
November 14, 2005 within the five day extension period allowed by Securities and
Exchange Commission Rule 12b-25.
