I used the mast as a ridge pole this winter, the crutch at the aft end broke either due to wind or snow. A nice gouge was made in my mast about 5 inches below the holes for the lowers, when it hit one of the nuts on the keel hoist. It's about 1 1/12 inches long and about 1/8 inch deep at its deepest point. Is the mast still safe to use?
The picture sort of shows it.
