Abstract:

From 15 January through 15 April 1982, the U.S. Combat Support Base USCSBMK I was tested on the Connecticut River, in and around Hanover, New Hampshire, to examine its operation on an ice-covered waterway. The objectives were to determine to what extent shoreline ice would affect launch and recovery and if the boat could create an ice-free channel across a river so that a ribbon bridge could be floated. Shoreline ice can inhibit launch and recovery, but several solutions were developed to reduce or eliminate these problems. The boat can, to a limited extent, be used as an expedient icebreaker. It can break competent ice sheets 3.5-4 in. thick as well as significantly thicker thaw- weakened ice sheets. Sheets of well degraded end of season ice up to 13 in. thick were broken.
