I am in the process of re-building an all aluminum Coast Guard Patrol Boat. It is 22.5' long, beam is approx 8', gunnels are a good 12''wide, was foam filled both sides, around engine and has a bulkhead in bow so it would float 6" out of the water if capsized.
Had a Mercruiser (VM) diesel engine 220 hp with a Bravo II outdrive, center console. Weight is approximately 4,750lbs. originally.
