Changing Rudder Design

[zboss]

DON'T FLAME ME!

Have no plans to change....don't need to know how stupid the question is... don't need to be called crazy... just satisfying curiosity.

All Cabo Rico's are built with solid fiberglass rudders with 1.5" aquamet steel. They are extremely heavy barn door rudders.

Is there any need to stick with the same exact super heavy rudder? If we found ourselves needing to rebuild our rudder at some way off land in the future is there any advantage to building a lighter rudder or changing the dimensions? Basically modernizing the rudder.
