Now you're claiming that when a cat flys a hull it's actually heeling???????
HEY STUPID!! Most cats can fly a hull. They can? Hmmmm. Didn't you say most only heel 5 degrees? I suggest you might be confused between listing and heeling. No surprise! Bwahahahahahaha! RB |

There you go again Nutsy,
Put your own spin to a discussion. DSK had no problem with 20-to-15 degree heel. Either did I. Yes "Shaw" did design his to stiffen at around 15 Deg. Any sailor know some heeling needs to be had but skippers have been working for year to keep the sail plan upright. That is why the "Rail Meat" lines the weather rail. Solo racers pump water ballast around the hull. Almost anything to overcome the bad effects (Evil) of heeling. Hiking straps, trapeze.curved sliding seats on the international canoes Now, Nutsy, you tell me what racing boats or cruising boat(Mono) are designed to go faster with their masts heeled 30+ deg. In fact name a vessel regardless of its design that sails faster with a heeled sail plan and I'll shut-up. Not one that YOU THINK but one that sails fast and better with the mast heeled. Ole Thom |

Nutsy'
Reached hishest speed on a reach with a 15 deg heel Are you saying it wouldn't have gone faster at a 12deg heel? Did you try? Did you have crew high siding to get the 15 deg? Nutsy, Shaw designed hulls to stiffen at 15 deg approx. but they didn't become stable at that heel. They had to be ballasted to hold 15 degs. Think about what you're saying! I've seen to many P30's sailing with high side rail meat. By the way, Nutsy, that also goes for the C&C Ole Thom |

Ol Thom, you are missing the point. As the wind grows the boat heels.
More wind = more heel until the VMG drops due to leeway or the boat sinks. To control that leeway you eventually have to reduce sail or sheet out. Now the question is, at what angle does that occur at. I've mainted that 30 degrees is about the limit for *most* keel boats and have posted references showing this to be the case. In the case of IACC yachts, 30 degrees is typically the design heel for max VMG. Some keel boats such as the Beneteau F series have a lower angle (22-25 degrees). But to suggest that highest VMG is seen at 15 degrees heel (or even 12 as suggested by Doug) is completely wrong. You need to heel to extract wind energy...

Bobsprit wrote: This heeling maybe increasing water line lenght but at the same time it is decreasing sail height, decreasing keel depth. decreasing rudder depth. Probably increasing leeway A heeled rig may still be optimal. All boats make some leeway. The original point was about a heeled design going faster than design sailed flat. On the P30 we observed the highest speeds on a reach with a heel factor around 15. RB On a reach? What about on a beat? Cheers |

Well if you must open up the discussion to all monohulls then, have you never seen a dinghy heeled to reduce wetted area? :) Cheers |

No, I'd say you have no idea what you're talking about.
Let me try and explain, even though I know it's futile in your case... During normal sailing conditions, most cats heel up to about 5 deg., some a bit more, some less, depending on the conditions and the boat. On the other hand, when things get out of control, as in the case of a cruising cat, one hull lifts off the water, thus "flying." Disaster is sure to follow. If the cat, such as many a hobie, flys a hull, that's probably intended if the sailors know what they're doing. If they don't, it soon goes over, and then they learn something (something you seem incapable of doing). Back to you mental juvinile.... "Bobsprit" wrote in message ...

Heeled to reduce wetted surface? Nav, is that supposed to be an answer
to a vessel sailing faster with a heeled mast? I think you are just blowing smoke. Thom |
