Thanks Bud ;D the location is about two feet from motor well wall on starboard side of tank, about six inches away from the tank / hatch seam that is caulked. Is that what you mean by thin stringer. From what I remember seeing on this site somewhere there are two main beams, one on each side of the gas tank running stern to bow bulkhead and there are smaller ones that run off of that to the sides of the hull. Are those side ones the thin stringer floor support you mean.
