I have a horizontal crack in my port coaming. Looking for ideas to address. Hasn’t fully separated, but cracked enough to wiggle. Afraid it won't survive the season unaddressed.
A dowel jig and long bit would allow drilling several top to bottom 1/4” holes and epoxying a mahogany dowel in the hole, but I’m thinking that a dowel won’t do much for reinforcing the inflection point of the crack.
Maybe there are 1/4” bolts that are long enough. McMaster-Carr has threaded 1/4” 316 SS rods, but not sure about how to terminate on the top of the coaming. Maybe machine a flat-head screwdriver slot in the top of the rod?
Also thought about a 1” SS 1/8” flat bar - kind of like perpendicular Band-Aids. Maybe also some angle bracing on the outboard side.
I’m thinking the fix may be unconventional, so open to suggestions.
Photo is of the crack - the yellow line is the outboard deck level opposite the photo.
