Thanks Dave, Does anyone know if the 17s have "positive flotation" blocks installed? Thanks, Ben ben: the M15 has 'positive flotation' in the form of foam blocks installed at the factory. the two foam locations are: under the cockpit floor, in the bow (in a screwed shut locker). the hull is solid fiberglass - not a floating sandwich like a 'whaler. so without the foam the M15 would sink. i have no idea what the 'lift potential' is for a swamped M15. thing is ... i've never read that an M15 has been swamped - neither by accident or by design. i don't believe the M17 has positive flotation. i'll be corrected if wrong ;o)- in a short bit i'm going to post some interior shots of my M15. this will show the foam locations. the link will be shared on this email list. dave scobie M15 #288, not yet named Ben Smith wrote: So forgive me on the confusion but I don't yet own a Montgomery. Are these boats made with foam in them to give them buoyancy even if knocked down (like a Boston Whaler)? What is the extent of a Montgomery's reserve buoyancy, what is installed at the factory?
