Ok the Aussie Blade was 111.7kgs - not bad for first attempt.
How many attempts do you think I invested in my F16 ? <img src="http://www.catsailor.com/forums/images/graemlins/grin.gif" alt="" />
The system you propose sounds too expensive for manufacture & expensive to maintain.
Ohh I understand now Marcus, you are refering to a setup I placed on this forum several months back. In this thread I'm just talking about permanently fixed T-foils to a standard EU Blade rudder board. Basically the angle of attack of the T-foils is set to somewhere between -2 and 0 degrees with the boat right on its optimal waterline. So when the boat is sailed at low speed or on its waterline then the T-foils won't add much drag at all. There are no moving parts anymore, the two screws used to fit the T-foil to the rudderboard are also used to fine-tune the angle of attack to the -2 to 0 degrees range. Ones set up the gaps are filled with filler and resin and the whole setup is fixed.
I don't see this as very expensive or difficult to manufacture. It is basically the standard EU Blade rudder boards with a T-foil bolted to its tip. It uses all the same hardware as the conventional rudder would.
