Thanks Marc, I know the pipe, what is the gong? My boat is a 16 1/2 foot, 7 ft wide, Duracraft 75 hp Coast Guard rescue boat (1962). I'm putting in a 25 gal. gas tank, extra flotation at the floor, livewell, boxing in most of the open back & adding a 9.8 hp kicker. Being safe, how far out would most boats this size go? Watching the wind & conditions, of course.
