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 |

Not true! A boat permanently at dock (like yours) would never make leeway.

Poor Gayanzy...even in his trolls he's wrong. Floating marina's do in fact make tiny amounts of leeway. RB |

When you're right, you're right. I'm sure this is the extent of leeway for
you and your boat! YOU WIN AGAIN! "Bobsprit" wrote in message ... Not true! A boat permanently at dock (like yours) would never make leeway. Poor Gayanzy...even in his trolls he's wrong. Floating marina's do in fact make tiny amounts of leeway. RB |

Hey Nutsy,
Just think how much faster you'd go if that same wind was pushing you on a "Iceboat" without any heel. No need for increased hull lenght. Think how much faster you'd go on a sailboard with no heel with the sail streaight up. Consider the better speeds capable by Multi hulls without the "EVIL" of Heel. You don't have to call it Evil but it is a unwanted action of a displacement hull as soon as it comes off the wind and starts going across or up wind. I think of it as "EVIL!" AND: "I'LL DRINK TO THAT!" Ole Thom |

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 |

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...

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

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 |

Now, Nutsy, you tell me what racing boats or cruising boat(Mono) are
designed to go faster with their masts heeled 30+ deg. First you accuse me of "putting my own spin" on things, then you ask the above absurd query. I've never indicated anything but moderate heel, certainly less than 20 percent. Obviously, at 30 things are being pushed, the boat will slow and VMG is compromised. RB |
