I owned a 23 cc(twin 225's). It is a smooth ride, but the hull is heavy. It will get very sluggish in rough water(18degree deadrise at the stern). The sportsman and coastal series were a Larry Smith design. Designed more for south Florida and California waters. No real discernable bow flare, and a flat 39 degree deadrise at the bow. Makes for rough entries. All in all a good hull, but sluggish in the rough stuff and a whole lot more wet than a v-20.
Honestly, the v-20 is a better hull. The 23 and 25 are of course bigger, but do not give the hull performance that a v-20 does. They also burn a crapload more fuel.
I would stick with any v-20 manufactured after 1985. Earlier models are good too. Just the post 1985 models were built using heavier cloth and a hot molded transom.
