Incat Crowther Designed Ferry for Seychelles

Incat Crowther has designed a new catamaran ferry for Cat Cocos of the Seychelles.

To be built by Richardson Devine Marine, the 292-passenger, 30m vessel will capitalize on the experience of the operation of the Incat Crowther-designed Isle of Praslin (delivered 2006) and Isle of La Digue (delivered 2009). These vessels have proven to be reliable, robust and efficient through years of operation, and the new vessel is designed to take those characteristics a step further.

The vessel will feature a shallow draft, including the use of an efficient propeller tunnel to afford access to the operation’s confined harbour berth. Propulsion is via Cummins main engines, running at modest engine speeds, which will combine with hulls optimized by CFD to deliver low fuel burn. Maintenance is facilitated with a large engine room access and clear engine removal path.

As with all Incat Crowther-designed vessels, attention has been paid to highly-loaded areas of the vessel’s structure, providing a robust and durable vessel. The structure has been optimized to the route’s specific sea conditions, using Incat Crowther’s in-house FEA systems.

The vessel’s 292 passengers will be in three classes, Interior Economy, Exterior Economy and Business.

Loading of the vessel, including baggage handling, has been optimized, with four access locations on the port side. Luggage is directly loaded to the enlarged luggage room via the aft-most ramp. Economy passengers are loaded via the next two gates, with those destined for the upper deck aft exterior space afforded a clear path to the aft stairs. At midships, a boarding location is reserved for business class passengers, who feed directly into a dedicated staircase to the business class cabin.

Multiple features have been implemented to enhance passenger comfort, including a wave breaker, an active interceptor ride control system, natural fresh air ventilation, large windows and blinds in the business class cabin to reduce heat and glare.
