um Yes I am planning on cutting out sections. I dont know how big of sections I will cut. I do plan to cut out all the bad core before i start recoring. Also I really hope to save the fiberglass and re use it ... Im not sure how exactly this will go. I am also reinforcing the chainplate bulk heads, cutting into the cabin sole to reinforce the compression post and rebedding all deck hardware. Hope to have this done by June first. Im in Milwaukee WI so most of the winter is too cold to lay any fiber glass so this will be a slow project ... My boat still needs to come out of the water and get covered. It may be a few weeks before I start cutting into the roof . Again I am planning to keep running posts of these projects.
