Thats what i was leaning towards just seems like it would be stronger that way. Do i need to allow a way for water to get by the stringer (like a hole or some sort of passage) not that there is going to be any leaks but just in case somehow water gets into the hull i know if the job is done right and the boat is taken care of there should be no water in the hull since its its a tri hull if water does get into those outside parts of the hull there will be no way to get it out right
