Had the same problem with my boat - only more rivets along a bow stringer. Problem was initially solved at the marina where purchased. This included, luckily, only removing the bow casting platform and re-tapping the original rivets. To make sure the fix was perm
anent I also applied a tubed compound called Sicoflex which can be purchased at most marinas in a variety of colors. Apparently, this product is used on the west coast for some pretty major damage. The boat has remained dry under all sorts of conditions.
Having said this, remember it is an aluminum boat and a small amount of water in the bilge is of no real concern with an appropriate bilge pump. Enjoy the w
ater and fishing!
