incredible isn't it...

One issue to keep in mind is that more heel = more weather helm. If
you're dragging your rudder sideways, you ain't going fast!


However, there is a sweet spot where the boat will gain WL, have good

VMG
and
not increase wetted surface.
The rest is gobbily gook and pretty obvious. Clearly a vessel heeled to

far
won't make much VMG and have a flawed track.


Well, smack me about the head with a pair of old mackerel!!!
Bob is trying to take part in a sailing discussion, ... *again*!!!!!

Nutsy,

I really am not happy getting into this discussion but I'd like to
remind the "heelers" that you can heel a boat to a capsize without
forward motion.

A well trimmed boat will be the boat with max forward motion with min
amount of heel! ALWAYS!!

Heeling is a necessary evil to sail power and should be kept to a
minimum. If your boat is heeling 30 Deg or more, it means you are
shortening your affective sail plan height, your sail plan is getting
outside of your hull plan ( Causing weather helm).

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

Try keeping the sail above the boat and not to the side and you'll sail
fast and better

Get the boat back on her feet. Nothing good happens bent over!!

"I'LL DRINK TO THAT!"

Dumb Question BB,

The logic is faulty? "Which is faster a 10ft Kayak or a 14ft?" If ,as
you say, keep the same proportions, a 100ft kayak with the same Guy
paddling should be way, way faster. NOT SO!!

This is not rationonal, since some heel and resulting extended WL is an
intended function of a given design. It's not an "evil" but a known factor that
designers considered and worked with. Calling heel "evil" would be like calling
wetted surface "mean."

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.

Heel isn't evil, its just silly. You could spill your drink! Everyone knows a
proper boat should sail perfectly upright.

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

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!"

BB,

I own an 11 foot Kayak. I know what you're trying to say. I still say
your logic isn't complete.

Have you even considered a Racing Canoe/ Kayak? I know you haven't. You
have locked yourself in with certain limits in your own mind.

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