I've cruised since buying my stealth, although it is pre-F16 (503), and have just returned from a weekend cruising the blackwater estury. I've two mains of 12.5 and 10 sqM and a jib. I check the forecast and choose sailplan for maximum wind strength, so anything from 15 to 10 sqm. The 10sqm is full length luff, just shorter foot. Problem is when blowing hard, F6+, the full length luff puts the power too high up the mast. If you're going to change a sail, I'd suggest normal reef points on the main, above batterns? Also as you reduce the main, ideally you'd reduce the jib so a furling one would be ideal. Only problem I've had was yesterday off Brightlingsea in a force 2. We tacked, there was a bang and the mast went over the side snapping the gooseneck fitting as it went. All the rivits holding the mast ball to the main beam had sheared off, 11 or 12 years of abuse? Anyone know where to get a new mast ball and gooseneck for rectangular alloy boom as I love the boat but can't really justify buying a replacement?
