Two Incat Crowther Boats Under Construction

(Press Release)
Friday, May 04, 2012

Two Incat Crowther 55m Catamaran Crew Boats, to be named SEACOR Lynx and SEACOR Leopard, are under
construction at Gulf Craft LLC in Louisiana, USA.


The vessels’ operator, SEACOR Marine, is a progressive company that pioneered the use of fast catamarans in the offshore industry with the commissioning of SEACOR Cheetah in January 2008, and SEACOR Cougar in April 2009. The operator intends to push the boundaries even further with these larger, faster vessels, by offering increased capacity and comfort.

The vessels will each be powered by four MTU 16V4000 M73L main engines, which will drive Hamilton HT-810 water jets. The vessels will have the capacity to reach speeds in excess of 46 knots.

Extensive seakeeping studies were performed to develop a design that not only improved passenger comfort, but also increased operational efficiency. The result is a vessel that reduces motions by an average of 20%, with vertical acceleration reduced by 40%.

As with Cheetah and Cougar the cargo deck is lined with hardwood inserts, and protected by heavy duty cargo rails at the sides. An optional landing rig for surfer class vessels can be fitted amidships. The vessels will have the capacity to carry 150 tons of deck cargo.

The combination of four reversing jets and 2 retractable azimuth thrusters, coupled with a Kongsberg control system, provides the vessels with dynamic positioning in a wide operating area. The vessels will have DP3 capability.

The main deck passenger cabin seats 150 at an increased pitch, whilst comfort is further enhanced with increased luggage space and additional toilets. The main passenger cabin also houses a snack bar. The upper deck wheelhouse features forward and aft control stations. Outside are fire monitors and rescue boat. As well as excellent forward and aft visibility, direct stairs are provided to the foredeck for quick and safe mooring operations. The hulls accommodate 14 crew in a mix of officer and non-rated cabins. The port hull features galley and mess facilities.

Incat Crowther is proud of the relationship with SEACOR Marine, who is proving an ideal partner in progressive, forward-thinking vessel design. It is anticipated that these new Crew Boats will further push the boundaries and enhance the services offered by SEACOR Marine.
