The EC-12M is one of the one-design classes comprising the AMYA-recognized fleet. Class specifications govern virtually every aspect of these yachts from hull and sail design to permitted remote controlled functions. Approximately 5 feet long, with a mast standing about six feet over the deck, the EC-12M weighs in at about twenty-three pounds.

Originally a towing tank model for a Charley Morgan twelve meter, the EC-12M can be transported in all but the smallest of cars, sailed in shallow waters, and in winds from mere zephyrs to light gales. The hull is shaped so as to shed dead leaves and other flotsam, an important feature when sailing on inland lakes and ponds.
