I have that exact same one on my H26 and I had to replace mine as well.
Make sure you have a Z-Spar mast.

It is a rather straight forward repair. Simply slide the new foot into the base and then drill holes for the rivets. Put in the rivets and pop them.

You will need one of these (Lowes or Home Depot etc)

Can you post a photo of broken part. Also look on the boom and mast for any identification as to mast mfg. it can be either a Z Spar or Kenyon Isomat

Hi Dave,

Thanks for your reply. Here is a close-up photo of the broken part. Z-Spar mast.

Hi rgranger,
Thanks for your reply. Yes, our mast is a Z-Spar. Yes, I think a rivet gun is required equipment for a used boat owner. ;) Glad to hear that it was as straight-forward as it looks.

It looks to me like the upgrade mast foot is less tippy when raising? I’m guessing this is how the original one was cracked.

I would recommend using aluminum pop rivets when you put the foot onto the extrusion, not stainless. That way if the mast should ever sway sideways while stepping or unstepping the rivets may sacrifice instead of ripping slots in the extrusion. Keep in mind the rivets only serve to help keep the foot in place when the mast is not vertical.

And don't rely on the strength or design of the foot and tabernacle to keep the mast from swaying sideways, it is way too weak for that. Use a few helpers to steady the mast and/or rig a baby stay system to help steady it. I personally would not try to do this alone. If you try to raise it without robust side support of some sort it is likely to tilt to the side and at minimum do damage at the mast base or even lose the mast (and maybe you) entirely.

A well designed mast raising system should not include a line item for failure. Thats an irresponsible approach that could kill somebody.

How do you remove the old rivets? With a drill?
