I'm performing a cabin window replacement on my 1984 MacGregor 25--out with the pink and in with new. Question: Can I increase the area of the window opening without compromising the cabin top strength directly over the windows? I plan on increasing the hallmark pink windows with a light gray polycarbonate, which is thicker than the stock window acrylic and will be bedded and fastened more securely than the stock windows. I am assuming the 1/4 inch polycarbonate will be acceptably strong with adequate fasteners. Opinions wanted. Thanks
