So is the problem up and down slippage or rotational?
I would have thought it should rotate, but not move up and down, in which
case some kind of araldite on rings top and bottom would seem to be needed.

I do a bit of windsurfing and the masts have got narrower over the years. I
have an adapter that goes on the mast and then the clamp on the boom clamps
to the adapter. Unfortunately the adapter is made from a fairly hard
plastic and the joint slips.

It is just a round pole with a round clamp, the clamp is oversize.

I want to make my own adapter and had a look on ebay.
I saw two possibilities.
Silicone sheet and reinforced conveyor belt, both at 6mm thick.

Any thoughts for a good material which will not let the clamp slip down?
thanks

Some Dycem bought.
Hopefully no swearing at the clamp next time I am out.
