Downwind Pigs-IOR Type
When we shorthauled the 35s5 the surveyor and a few of us got into a
long discussion about the IOR influence on the 35s5. Her sucked in tail section, how she picked up generous waterline when heeled...a big debate broke out about downwind sailing. "They're pigs downwind and it takes a lot of talent to go fast." A few nods of agreement. The boat's name, Windward First is a joke about how fast she is on that tack. Dead downwind can be rough. Other discussion about how it was important to keep her nose up with a modified set of the chute, sacrificing some shape for downdraft, but I don't have enough experience with chutes to understand the nitty gritty. Her owner says we'll fly the chute the day before we decommission her. I found the boat fast downwind, but I wasn't racing of course. Racing is sometihing we'll try with her, but it's far from a top priority. As a cruiser she'll be faster than most. Then another discussion started about her wing. The owner said she was quicker to semi-plane with the wing than his previous deep draft model. "But there's more wetted surface and the foil is for lateral pressures/lift and can be counterproductive downwind", came another remark. Her owner said this wasn't the case. Anyway...thoughts on this? I'm no performance hound but I listened with interest to all. None of it matters much for our intended usage, but this will be my first "performance" boat so I want to know more! Robert B 35s5 NY |
