The 235 came with a fin or in most cases, a wing keel. Mine''s the wing keel. It''s a full batten main and a 150 on hanks. Both sails are apx. 2 yrs old and in excellent shape. All the rig dimensions are very close to a J24 and a PHRF rating of 204. It does pretty good in 8+ knots of breeze but those days are few and far between on an inland lake. This weekend I''ll try a aysmetric.
