"Ever wonder what the O2 deck is made of? Two layers of three eights inch fiberglass sandwiched on a 1 inch piece of foam." -- Kenny Bishop, Highland Mary 37VT17
Kenny Bishop is installing a cable chase inside Highland Mary's smoke stack.
This penetration has historically been an LNVT trouble spot as it can allow water to leak below deck and into the galley headliner. Kenny's solution is two-fold: seal a PVC fitting to the deck and elevate the fitting above the deck.
