Looking for some insight on this boat for a friend of my Son's. It is a 1979 19' bubbledeck jet. Berkeley w/ 2 wedges, Hyd. Place Diverter, fairly stock 454. I know Howard makes very good boats and still does. He is wondering about the Hull Characteristics: are these heavy boats? Slow speed Hull? Not looking for 100mph racer just 70-80mph lake/river toy in the future with some upgrades of course. Is this boat capable of the 70-80 mph range. Any insight positive or negative would be greatly appreciated.
