Kvichak Marine has delivered the first of two foil-assist catamarans built for the United States Army Corps of Engineers (USACE) Mobile District. Dubbed S/V Irvington, its primary mission is to conduct hydrographic surveys in support of dredging and channel maintenance operations. The second vessel, which has a summer delivery, will operate in the New York District. The 54 x 20-ft. aluminum catamaran incorporates the Hysucat foil design, a system which is designed to provide the operator with increased fuel efficiency; improved speed and low wake wash. The fully adjustable aft trim foil provides ultimate control for variable loads and sea conditions. "The Irvington is one of the most efficient vessels that Kvichak has ever built," said Scott Weiler, Kvichak's project manager.
