Hello Dennis, Thanks for the info on your M23! I will be happy to measure my boat on it's trailer, but it is 100 miles away in storage for the winter. I don't know how soon I'll be back down in that area. Theo has his in a pole barn a bit closer to St. Paul, where he lives. How about a rough guess-timate? Length 26 feet Width 9 feet Height 14 feet. I tried backing it into two car washes to spray the bottom after haul-out and I couldn't make it into either! Both had tall doors. Theo's bronze ports from New Found Metals are very classy.
