21' x 7.5' SHALLOW DRAFT RESPONSE VESSEL

This vessel is designed for shallow water general utility operations in rivers, estuaries, or tidal flats.  The 115 HP outboard motor with a water jet lower unit is installed on a jacking plate so the vessel can operate in water as shallow as 16".  Top speed is 30 kts and there is a 40 gallon fuel tank housed in the console.  This hull could be powered by as little as a 60 HP motor and still reach planing speeds.  There is a large bench seat in the stern and a slightly narrower one ahead of the console, both provide ample storage space.  There is a towing arch for light duty towing applications.
