But if you put spacers under the top pivot block, you're not changing the relationship between the rudder's center of lift and the pivot axis - the distance from the center of lift of the rudder and the pivot axis is what changes the load on the helm. Since this geometry would stay the same, it would have no affect on the helm since you're just angling the whole assembly.


I'm not so sure that's right. Here's how I see it. With the boat level and rudder down, measure half way up the rudder pin make a mark. Now with a level held vertically at that point draw a line down the rudder. Now space the top gudgeon and use the level again.

I think you'll find there is more blade in front of the mark on the rudder pin. You have moved the center of the pivot point back in relation to the blade and the blade forward so a little goes a long way.

If that doesn't make sense then I'll go by the fact that Robbie's T is set up that way. <img src="http://www.catsailor.com/forums/images/graemlins/smirk.gif" alt="" />
