Quite a few around here in Finland and in Sweden. Was later replaced by 999. Flipper have a reputation of building solid boats with good seakeeping.
Apparently a danish journalist did a trip from Denmark to Gronland with a 909 and was happy with the boat.
In production from 1988 to 1994. IMHO best to look for a boat with a KAD engine and bigger sterndrive as the boat is a bit heavy for smaller/older volvos.
We had one of the smaller ones in -87 and she is still around and looking good. I don't have first hand experience on 909 though.
