This is a very good question that brings up my situation of modifying an original design in either material or structure. I am no naval architect or engineer...I'm about to replace my steel beam at the bilge level with a coated aluminum.

Is the design intent of the original boat spec a concern? Off of the dock, who should make this call...designer has passed on...common sense or local shipwright? Right now, it's a novice me making some important structural decisions.
