Actually I agree w/Will's description, except for the reference to ***lee*** helm. For me it's ***weather*** helm.

In moderate winds (say, 10 knots, +/-) when climbing to windward, I often find the mizzen contributes enough to weather helm to neutralize its benefit. I.e. w/it up the bow wants to climb into the wind, and so correcting helm is required, where as w/it down in winds like this nearly no helm is needed. Speed through the water is about the same in either case.

This is only the case when one is really climbing uphill in moderate winds. With the wind freer, the relationship is less delicate. I.e. on or around the beam, I can carry full sail deep into the day and just plow away. In really light stuff, nothing helps.

Hey, Randall.....

What I described to Will is the advantage of the mizzen beating in "Strong" winds. Without the mizzen the sailplan is very much forward and leehelm is almost guaranteed. What the mizzen will do in such conditions is bring the bow closer to the wind. At least that's what worked for me :-)

I'll have to try that. I must admit I've not noticed much lee helm when close hauled, but then we don't get very strong winds here in San Francisco Bay. hee hee :)

My wheel has a brass cap on the handle that points upward when the rudder is straight. As the wind pipes up, I have to compensate for the mizzen by turning the brass cap toward the downwind side of the boat (port on a starboard tack). Is this lee or weather helm?

I know it's time to reef (or douse) when the cap points straight down.

Think of it this way. On a close reach, if the bow wants to go into the wind (to weather) and you need to employ helm to correct this, that correction is weather helm. Conversely, if the bow tends to move off with the wind, and you need to employ helm to correct it, that's lee helm.

My guess is the term originated when tillers were the rule. So, if you have to pull the tiller to windward to keep your course, it's weather helm; to leeward, it's lee helm.

What you describe above is weather helm.

(It's confusing.)
