I just signed up to the Forum today. I have a 2015 C275S hull #29. I love the boat, having had several much larger boats that I always needed crew to sail, the 275 has brought the simple joy of single handling back for me. I thought of racing the 275 and bought the 100%, 106% and the A sail. Unfortunately, Narragansett Bay PHRF gave the boat a rating of 131 spinnaker and 150 non-spinnaker. That puts the boat just slightly slower than the J-80's rating. Obviously, I don't race the boat, which is disappointing. Is there going to be a dedicated 275S forum? I'd love to hear from other owners.
