ok i just got a 1972 hurricane,forcaster 150 tri hull. i did know that the rear half of floor was bad. rotted. and top 8 " of transon is soft.because the splash well drain tube was missing . how is the best way to go about removing the very thin fiberglass over lay on top of wood. now i live in a apartment building .working out on the street.i have a 12 volt cordless drill. what kind of cutter do you think would work to cut through the thin glass floor? for the transom would using somthing like "rot doctor" be ok to use ? its got a evinrude 50 HP on it now. any one have any ideas. or a super low cost hull for sale i'm in illinois 60 mi SW of chicago
