That is impressive work and a lot of it! I like the way it looks. I am going to do something about my ceilings because of other work I am doing but I had not considered glassing it all. Do you think you have added much weight? My 1977 hull has a vinyl ceiling with access zippers. A couple of the zippers are fused and the edges of the ceiling is coming loose in places because the staples holding it have rusted. I am considering teak or mahogany lath and trim.
Consider a Lavac head. I installed one and am very happy with it. it adds an emergency manual bilge pump, too. I will collect some pics of that install.
