Double conversions

[Mariner]

My son is actually a reformed four boat man, thanks to a 12 step program aka an addition to the house. In last two months he sold and bartered a 23 ft. '75 Sceptre (#1) and a 20 ft. 72 or 74 c/c (#2). Too bad he didn't know about this website. They were classic seacrafts unlike the 20 double conversion (#3). He and I co-own (#4) a 1966 19 ft walk-through which I have considered converting to a c/c, but it is in good shape, so probably won't since I don't know how it would turn out.
