BG - I'm assumed that you were talking about the formula splash 1976 - 1983 Mako 25's. They are good riding hulls same as formula 233, albemarle 24, early contender25, seavee, whitewater, rampone, competition, bluewater23/25, Tsunami 23, and the thousand others. If you are thinking about getting one . . . I would suggest buying one of the better built knock offs over the rott box Mako . . . If you weren't going to buy a 23 seacraft.
