As the mast section is round, one can just have a fitting on the end of the boom that is a fork and have that slide over the mast. Well, at least that is how my design has it.

As a kid we used to have a half round welded to the boom that sat on an upturned oar rollack (plastic) that was riveted to the mast, vang held it in place and while it got chewed up in a season, could easily be replaced and was cheap. Problem here is that we have slip fit everything and you can't rivet into slip fittings....one way or the other even with this suggestion, you have to weld something
