Rubber wedges--old tire?

[Ian McColgin]

Of a group of us who rig and unrig our boats together, three have spartight. Generally if we remember to use Ivory Liquid to lube between the mast and the spartight and the spartight and the partners' hole, it was not too horrible a chore. But because the holes - these are glass boats with aluminum masts - are parallel sided rather than very finely tapered, there's perforce a bit of gap on both sides of the spartight. It's so slight - remember the Ivory - that the owners don't have any complaints. When out with them in certain conditions I can hear and feel the vibration as a tapping translated into the hull but glass boat owners seem to live with a cacophony of metal on metal or plastic rattles that we woodenboat heads are not used to.

I think my prejudice is that I'd not use this method on a wooden mast. And I don't like the strain of getting the mast out in the fall.

And I like tapping wooden wedges in place.

Spartight is not evil. Just not so much for a retro like myself.

G'luck

Hi Ian,
Thanks for the context. Other than Vaseline at first installation, we never apply lubricant here. Of course, we don't take out masts regularly, but when we do, a few seconds of moderate crane strain will pop the Spartite free. I can't recall a difference on wooden, carbon, or aluminum masts, nor yet any tapping, so it would seem that there's either an installation difference that we are overlooking, or the tapping you are hearing is due to some other fiberglass-boat oddity.
Also, I will confess that I don't much like tapping wedges in, and distinctly don't enjoy whanging them out again.
Fair leads,
Brion
