I checked and it is through bolted. I expect that the screws ripped out of the mast step in an incident that occurred prior to my ownership of the boat. I expect that the holes were ruined in the accident and could not be reused. I don't think I can go back to wood screws.
My shroud failed at the contact with the spreader; I wonder if it was anchored to the spreader properly.
To fix this mast, I need to know the distance from the bottom of the mast to the through-hole for the mast bolt. Could someone measure that for me, and let me know? Thanks!
Perhaps I can maintain the same mast height by adding some material to the bottom of the lower mast plug, and drilling the new though hole close the bottom of the mast. The last boat I had was a Club 420, which had a groove in the bottom of the lower mast plug, and it sat on the mast bolt (the bolt did not go through the mast).

The boat is off the lake and in winter storage for the next six months. Here are two photos of my Hobie bob implementation. This approach, two aluminum extrusions and two aluminum plates, requires no drilling of the mast, just a slightly longer bolt through the masthead pulley.
