sorry Charlie you are off on this one your friend doesn't have that hull *21 CC then cause i had a 1986 21 Scorpoin and it was just the exact same as my 78 V20 *but the cap yeah it's totally different. you're thinking about a Seahawk 21 looks almost same but not but the scorpoin is.
here's a Scorpoin
here's a SeaHawk
