AMT Marine To Construct Utility Boat

AMT Marine expects to take delivery in May of a 136 x 34 x 12 ft. (41.4 x 10.3 x 3.6 m) mini-supply boat from Hope Services, Dulac, La. The boat, which is being designed by Frank Basil's Entech and Associates, will be powered by a pair of Cummins V-12 KTA38 MO main engines rated for 850- hp each at 1,800-rpm and driving through Twin Disc MG5301 gears with a ratio of 5.96:1. A 66 x 54-in five-blade prop from Padgett-Swan will be mounted on the end of each six-in. stainless steel shaft.

A computer modeling has shown a gain of up to 1.5 knots with this combination, and the five-blade props as opposed to four-blade. The boat is designed with a large 75 x 32-ft. (22.8 x 9.7 m) clear open aft cargo deck -equivalent in size to many 150-ft. (45.7 m) utility boats. Equipped with a 250-hp Thrustmaster tunnel bowthruster with hydraulic power from a 300-hp Cummins NTA855, electrical service will be provided by two Cummins 6CT 75 kW gensets.
