As usual it took about 5 or 6 posts for Old Frog to realize he hadn't been specific enough in his OP so here goes:
As a club sailor I get on (and race) a lot of different boats (38 or so at last count) and all but a very few have a
wheel rather than a tiller.
The range of the
wheel from center to
rudder stop varies from
boat to boat but is usually somewhere between 180 - 270 degrees.
If I know the total
rudder arc I can do the arithmetic and figure out how much
helm (rudder) I'm adding for any given degree turn of the wheel and therefore how much additional resistance the rudder might be creating in the
water, because obviously less is good; more is bad.
I was hoping there is an industry standard regarding full rudder
arc for sailboats with a wheel
helm since this information is next to impossible to come by on an individual boat basis.
Consequently, if all boats are different, as I suspect they are, I was looking for a quick, easy way to derive the degrees of full rudder arc without hauling out the boat or
diving down to inspect it empirically - neither of which are practical, at least not for me.
