HOUSTON,  TEXAS  (JANUARY  29,  2004)  -  Kirby Corporation ("Kirby") (NYSE:KEX)
announced  today  that  for  the  fourth  quarter  ended  December 31, 2003, net
earnings  were  $11,050,000,  or  $.45  per  share,  compared with a 2002 fourth
quarter  net  loss  of  $2,075,000,  or  $.09  per share, including an after-tax
non-cash  impairment  charge  of  $12,498,000,  or $.52 per share.  For the 2003
year,  net earnings were $40,918,000, or $1.67 per share, compared with 2002 net
earnings  of $1.13 per share, including the after-tax non-cash impairment charge
of  $12,498,000,  or  $.51  per share.  The 2003 fourth quarter and year results
were  in line with Kirby's published earnings guidance of $.44 to $.48 per share
for  the  fourth  quarter  and  $1.66  to  $1.70  per  share  for  the  year.

Revenue  for the marine transportation segment increased 11% for the 2003 fourth
quarter  and  18% for the 2003 year when compared with the corresponding periods
of  2002.  The  substantial increase for both 2003 periods reflected the October
2002  transaction  with  Coastal  Towing,  Inc. ("Coastal") and the January 2003
purchase of the inland tank barge fleet of SeaRiver Maritime, Inc. ("SeaRiver").
The  Coastal  transaction  consisted  of  Kirby purchasing 10 double hull inland
black  oil  tank  barges  and 13 inland towboats, and assuming the management of
Coastal's  remaining  54  active  black  oil  tank  barges.  The purchase of the
SeaRiver  fleet,  the  U.S.  marine  transportation  affiliate  of  Exxon  Mobil
Corporation,  included 48 double hull inland tank barges and seven towboats, and
the


                                  Page 1 of 7

assumption of the leases on 16 double hull tank barges. Operating income for the
marine  transportation  segment increased 3% for the quarter and 4% for the year
when compared with the 2002 corresponding periods. Since the spring of 2000, the
U.S. petrochemical business has been under pressure and, as a result, the marine
transportation  segment  has  had  only  limited  success  in  passing  through
inflationary  increases  in  its expenses in its contract rate renewals, thereby
lowering  operating  margins.

During  the  2003  fourth  quarter,  the  marine  transportation  segment's
petrochemical  market  reflected  a  modest  improvement  in  volumes.  Gasoline
blending  components  volumes,  part  of  Kirby's petrochemical market, remained
strong.  Refined  products volumes were as expected, fueled by scheduled Midwest
refinery  outages  for  maintenance,  as  well  as low Midwest inventory levels.
Black  oil  product  volumes  were  lower  than  anticipated.  Liquid fertilizer
volumes  improved  significantly,  driven  by  an  improved  farm  belt economy.
Imported  liquid fertilizer products replaced curtailed U.S. domestic production
to  meet  the  demand  to  replenish  low  Midwest  inventory  levels.

During  the  first nine months of 2003, contract rates remained relatively flat.
During the fourth quarter of 2003, contract pricing improved marginally for some
contracts  which  were  renewed.  Spot  market  rates  fluctuated over and under
contract  rates  during  the 2003 year, depending on market demand, fuel prices,
weather  conditions  and  other  factors.

The  diesel  engine  services  segment  reported  5%  lower revenue and 9% lower
operating  income  for  the  2003 fourth quarter compared with the corresponding
2002  quarter.    During  the  2003  fourth quarter, the Midwest dry-cargo barge
market,  under pressure since 2002, reflected signs of improvement; however, not
enough  to offset the weak Gulf Coast offshore oil service market and East Coast
marine  market.

Equity  in  earnings  of  marine affiliates, consisting primarily of a 35% owned
offshore  partnership operating four offshore dry-cargo barge and tug units, was
$723,000  for the 2003 fourth quarter and $2,932,000 for the year, significantly
higher  than the corresponding 2002 periods.  The improved results for both 2003
periods  reflect  close  to full utilization of the partnership's fleet compared
with  2002 results which were negatively impacted by vessels in the shipyard for
planned  maintenance.

During  the  2002  fourth  quarter,  the  Company recorded an after-tax non-cash
impairment  charge  of  $12.5 million, or $.52 per share.  The impairment charge
primarily  resulted  from reduced estimated useful lives on 114 single hull tank
barges  due  to our assessment of the impact of new U.S. Coast Guard regulations
that  require  the  installation  of tank level monitoring devices on all single
hull  tank  barges by October 2007, and the adjustment of book value to the fair
value of 21 inactive or out-of-service double hull tank barges and five inactive
towboats  that  Kirby  has  committed  to  sell.

Joe  Pyne,  President and Chief Executive Officer of Kirby, commented, "The 2003
year  was  a  challenging  year  for Kirby.  Although we saw some improvement in
several  of  our  core  markets,  we did not have any meaningful ability to pass
through to our customers the cost increases we have incurred over the last three
years.  As  a  result,  our operating margins for 2003 were below 2002 operating
margins.  Our weakest market during the fourth quarter was our black oil market.
Weaker  than  expected  black  oil  movements  to


                                  Page 2 of 7

power  plants  and  other  industrial  users  were  the  principal  cause of the
weakness. Petrochemical volumes continued to improve, but not to the extent that
the  third  quarter  GDP  growth  rate  might  suggest.  The  consensus from our
petrochemical  customers  continues  to  be that volumes will improve throughout
2004."

Mr. Pyne further commented, "The 2003 year was another year of strong generation
of  cash.  At the end of February 2003, after we acquired the SeaRiver fleet for
$35.6  million,  our debt totaled $297.1 million.  Capital expenditures for 2003
were  $71.4  million  compared  with $47.7 million in 2002.  We also made a $5.6
million  contribution in November 2003 to our defined benefit pension plan.  Our
contribution  policy  for  the pension plan is to fully fund Kirby's accumulated
benefit obligation.  At December 31, 2003, our debt decreased to $255.3 million,
a  reduction  of  14%  from  our  high  at  February  28,  2003.  Our
debt-to-capitalization  ratio as of December 31, 2003 was 40.7%, down from 45.1%
as  of December 31, 2002.  Our EBITDA for 2003 increased to $134.0 million.  The
increase  was  primarily  the  result  of the additional cash generated from the
operations  of  the  SeaRiver  and  Coastal  fleets.  In  addition,  significant
emphasis  was  placed  during 2003 on the collection of our accounts receivables
and  the  management  of  our  diesel  engine  services  inventories."

Commenting on the 2004 guidance, Mr. Pyne said, "Historically, the first quarter
is  our  lowest  earnings quarter due to weather conditions.  For the 2004 first
quarter,  our earnings per share guidance is $.30 to $.36 compared with $.28 for
the  2003 first quarter.  This is a larger range than we normally give; however,
the  first quarter's earnings are usually volatile due to weather issues and the
seasonality of the refined products and liquid fertilizer markets.  For the 2004
year,  we  anticipate  net earnings in the $1.85 to $1.95 per share range.  This
guidance  compares  with  2003  net  earnings of $1.67 per share.  Our 2004 year
guidance  assumes  the  U.S.  economy  will  gradually  strengthen  as  the year
progresses,  leading  to  improved  petrochemical  volumes  for  Kirby.  Capital
spending  for 2004 is anticipated to be in the $85 to $90 million range and will
include  approximately  $41  million  for the completion of 16 new 30,000 barrel
petrochemical  tank  barges  and  10  new  30,000 barrel black oil tank barges."

_______________________________

(1)  Kirby  has  historically evaluated its operating performance using numerous
     measures,  one  of  which  is  EBITDA,  a non-GAAP financial measure. Kirby
     defines  EBITDA  as  net earnings before interest expense, taxes on income,
     depreciation  and  amortization.  EBITDA  is  presented because of its wide
     acceptance  as  a  financial  indicator.  EBITDA  is one of the performance
     measures  used  in  Kirby's  incentive  bonus  plan. EBITDA is also used by
     rating  agencies  in  determining  Kirby's  credit  rating  and by analysts
     publishing  research  reports  on  Kirby,  as  well  as  by  investors  and
     investment  bankers  generally  in  valuing  companies.  EBITDA  is  not  a
     calculation  based  on  generally accepted accounting principles and should
     not  be  considered  as an alternative to, but should only be considered in
     conjunction  with,  Kirby's GAAP financial information. EBITDA for the 2002
     fourth quarter and year includes an $18,933,000 non-cash impairment charge.
(2)  Ton  miles indicate fleet productivity by measuring the distance (in miles)
     a  loaded  tank barge is moved. Example: A typical 30,000 barrel tank barge
     loaded  with 3,300 tons of liquid cargo is moved 100 miles, thus generating
     330,000  ton  miles.
(3)  Marine  transportation  revenues  divided  by  ton  miles.  Example: Fourth
     quarter  2003 revenues of $133,794,000 divided by 4,115,000,000 ton miles =
     3.3  cents.
(4)  Towboats  operated  are  the average number of owned and chartered towboats
     operated  during  the  period.
(5)  Delay  days  measures  the  lost  time  incurred by a tow (towboat and tank
     barges)  during  transit.  The  measure  includes  transit delays caused by
     weather,  lock  congestion  and  other  navigational  factors.
