Here is a mock up of the idea of the rudder control.
Ex Lex has twin rudders. The reason is mainly for ease of making the boat stear itself downwind but also for using as a drouge when having them in V-position each one angled 20 degrees out.
I hope to be able to stear from any position. a stearing line will run the inside perimeter of the boat. In addition there will be control lines fron the two hatches to V-position the rudders for breaking (car owners think Ackerman).
To achive this the tillers have connecting bar, but are not directly conneected to the bar but to trawellers sitting on the bar.
Normal stearing is done with the trawellers in zero angle position. When I like to brake the trawellers are adjusted towards the center and thuse the rudders are angled out. The lines controlling the trawellers are run to the rudder accis that they may not be affected by stearing.
This is a first try so I can only hope that it will work.
Some hardware is on its way.

Of course for those with a well lined wallet it can all be done more complicated using electronically controlled electricity.
