Picture of Annapols harbor craft

In a cutting-edge application of certified technology, The City of Annapolis contracted with Metalcraft Marine, Inc. to retrofit two diesel-powered harbor craft   with hybrid electric drives with solar battery recharging. The systems operate the boats on batteries for up to three hours at speeds up to six knots without     using the diesel engine. It takes approximately three to four hours to conduct a routine harbor patrol. 

MARAMA supported this project with a grant from the U.S. Environmental Protection Agency under the American Recovery and Reinvestment Act.  The 
Government of Canada provided additional funding assistance.
