Good to see others are thinking about rudder designs. Jim we have four
criteria for the rudders/daggerboard Jim
Baltaxe The biggest negative about the hull hung rudders, well the mk 2 version, is
they would be difficult to replace once the shear pins broke. At the moment
they are designed to 'break away' in the event of a collision. You would then
have to retrieve them from the end of the attachment line and refit them with
new shear pins. This may seem like a big disadvantage but it will only happen
in a catastrophic event which would render any catamaran with a stuck and
broken daggerboard at best and a split hull and bent rudder shaft at worst.
