Incat Crowther's Catamaran Ferry for Lomprayah

Incat Crowther delivered Thapdaorai, the seventh catamaran passenger ferry for Lomprayah High Speed Ferries. Constructed by BP Marine, the 34m vessel is an extended version of Lomprayah’s previous delivery, Maehaad.

The improvements over the previous vessel reflect feedback from the operation, as well as responding to increased patronage for the operation. The vessel has been lengthened in the mid-body, which in conjunction with the addition of aft pods allow for increased deadweight, which includes increased baggage and cargo loads.

The vessel’s windows have been enlarged to increase passenger outlook, whilst the boarding gates have been increased to aid passenger flow.

The main deck cabin seats 233 passengers, with increased luggage storage. The kiosk is located at the aft end of the cabin adjoining the crew mess and recreation room. The upper deck accommodates 20 passengers in the executive cabin, 50 in the VIP cabin and 58 passengers on the exterior aft deck. The roof deck seats 120. Total passenger capacity is 481.

Thapdaorai is powered by a pair of Yanmar 12AYM-WGT main engines, each producing 1340kW, and is capable of speeds in excess of 31.5 knots.

Incat Crowther yet again offered an extensive package of deliverables, including 3D structural design in addition to a full kit of aluminium structure and major components.

Thapdaorai is built to capitalize on the success of Maehaad. Her ruggedness and efficiency commend her to the demanding operation.
