Mastry Engine Center is well-known for its comprehensive training programs for recreational boat owners, dealers, the Navy and other customers. Recently Mastry expanded its scope, providing three-day training sessions for the US Coast Guard. Its first class included 15 USCG attendees from across the country, all currently serving on USCG cutters with Over the Horizon (OTH) craft on board. These are smaller, rigid inflatable boats powered by 315 hp Yanmar 6LPA-STZP engines and Mercury Bravo drives.
