ok so I am wanting to continue making her as custom as possible to continue adding some pizazz to the face lift of my 30 year old hottie. Oh how I love her so!!! Anyway, laying in my state room of my 88 345 Sedan Bridge, there are two inset shelves that run the length of my bed on both sides of the boat. Port and Starboard. The only ventalation or area to get air or to see anything (like sleeping in a box) is the center bow hatch and one ac vent and of course my door. I am thinking and would love and dont really see a reason why I couldn’t, unless it would cause some type of structural damage or loss of support, this the reason I’m reaching out to all of you. Is it possible to cut out and install some nice size port holes “windows” within those inset shelves on the port and starboard side? I would definitely have a professional do it, and im sure it would involve some new fiberglass and sealant applications to prevent any leaking. Boy what a difference it would make that room feel! If it is even remotely possible, I will be shopping around to find the best and biggest port holes I can put in. Thank you in advance! Captain Wardy!
