Hull thickness varies a lot
I can answer some of your questions. First, I don't know what specific kind of resin Macgregor uses. I'd expect it has changed over the years, having once been in the fiberglass industry. Second, hull thinkness varies a lot. In my '96 26X, it goes from about 3/4 inches or more in the high impact areas -- bow, etc -- to about 1/4 inches in the low impact areas. This is to keep the trailer weight down. We accidently put a hole in our hull (don't ask me, it's too embarassing) right in the head area and the glass was only 1/4 in thick there. Fortunately, it was easy to fix and the repair shop did a great job. (Ollies in Lynnwood, WA). Stoves and Heaters: We had Blue Water Yachts install a single burner alcohol stove. I have seen other installations that are also designed to be cabin heaters. The first couple of years, we heated the cabin with that stove and a couple of candles. But last year we added real heat -- an electric heater which required that I first install shore power -- and a alcohol heater from West Marine. The later is great. It puts out about 5000 BTU which is plenty and it doubles as a second cooking burner when needed. We have been quite happy with it.
