Re: Why a racer for cruising discussion...
The Sun fast 35 locally in phrf is rated some 20+ secs a mile faster, IRC it is also rated a bit faster. The SF37 is a bit of a dog for what it should be! The SO25 is rated about the same as an SF37. Both the SO and SF 37 need a bit more SA to really reach there potential. I know of a fellow in Austrailia that took and SO 35 and added 5' to the mast, now that puppy performs!
