Re: Backing up (or not)

I wrote an indepth article for GOB on rudders in the July/ Aug 2010 issue. I explain why full keel boats are "challenged" in reverse. It has nothing to do with how much the keel is cut away forward. It has everything to do with how far the keel goes aft. The arm between the center of pressure of the rudder and the center of pressure on the hull in reverse is just too short to give the rudder the upper hand. The more you eliminate keel aft and move it forward, i.e. fin keel, the better the boat will back up. The best boats in reverse are modern racing boats with big spade rudders and high aspect ratio fin keels.

Please visit my blog. It's fun to read.
