I'm planning on mounting a crab-pot puller and davit on my 20' Olympic (1988). The hull is glass and there is foam on the inside of the gunnel where I'd like to put one of the mounts. I don't want to drill through unless I know there's wood behind the glass. When I reach up underneath, all I can feel is foam, and I need to either drill into something solid, or be able to put a nut behind any bolts. Can anyone here offer suggestions for how to mount a davit on this hull?
I'll include a picture of the starboard side of the hull (just behind the cabin) where I'd like to mount it. I labeled the areas where I'd like to mount the davit brackets A (side) and C (floor). Any suggestions you can give me would be great?
