I believe that most of the 235''s were swing keel boats. The 235 are really neat boats in a lot of ways offering great performance and reasonable accomodations in a shoal draft boat. I also think they have well above average build quality for this genre of boat.
They are not the easiest boats to race. While they are really quite fast for a trailerable boat, they quite a bit of skill to keep them at speed. Also, in most areas they are rated close to even with boats like the J-24 and Kirby 25 which is a tough rating range for the boat to sail competitively.
