My second minifish ('74) was flooded inside due to a hull leak. Shortly after the bow handle pulled off.?The bow handle was apparently backed with a 8" block of wood.?
I dried out the hull by cutting inspection ports near the fore and aft. Also reinstalled a new handle backed by plastic cutting board material instead of wood.
I have some pictures of the hull one morning when dew condensed onto it.? You might get an idea of where the support foam is located based on that.?
