A question Dog;
If monohulls have one rudder and sometimes two (like mine) and Catamarrans have two rudders, how many rudders does a Trimarran have? In the picture you posted I see the windward amas has what looks like a rudder but could be a fixed fin. Also see the windward daggerboard is retracted but not the rudder or fin. Would a tiller on a Trimarran operate all three rudders at once? Just curious because I am not familiar with trimarran designs.
