Any idea of a price for these blades and rudder heads to hold them? I've heard about $1,000 US. Also, if the T foils make the rudders more effective, maybe the rudders could be shortened? That would give you a little more reaction time to see the bottom before you impact it and bust your $1,000 rudders!

Also, have there been any problems with the T foils coming off after long periods of hard use, or cracking where they join the rudder?

You all have noticed the America's Cup designers have been putting end plate type wings on their keels for years now, (but never on their rudders) of course for different reasons, but there must be some improvement in drag or they would have dumped them and they do computer testing, tank testing as well as side by side. It must work... <img src="http://www.catsailor.com/forums/images/graemlins/blush.gif" alt="" />
