If the center of effort is forward of your center of lateral resistance doesn't that give you lee helm? So once you take your hand from the helm your boat will bear off and eventually jibe?

If that's the case then that, in my point of view, is a dangerous thing to have designed into your vessel.
that's why you have the mizzen mast and sail to balance the boat.
this is a Ketch we are talking about .
I think that's how it works

cheers

You forget when the boat heels the CE moves to leeward and gives weather helm. How much depends how much you heel. To counter too much weather helm the CE must be a bit (5 to10 %) forward of the CLR. A ketch can adjust the CE back and forth easily by it's more longitudinally widespread sail plan.

Hi, I just experienced this very thing. Are you saying I should be able to adjust the sails so I don't get tired pulling the tiller to me for hours? The boat was heeled over as far as I have had it, but continually wanted to come into the wind. Do I tighten the jib, loose the mizzen? What about the main. I was on a beam reach.

Any and all help is greatly appreciated. But WOW! sailing is so much more fun with actual wind!

Re: Looking at a ketch

loosen the mizzen would be one way... or douse it. If that doesn't work reef the main also.
