You know where the mast goes through the deck? Is it fixed in the metal
ring perhaps with a big bolt? It's just that if you were interested in
altering rake my adjustments at deck level it would be impossible with a
bolted partner... Instead you would have to alter rake at the mast foot
and that is also impossible on many boats as the foot casing is welded
or bonded to a ring frame.


I think that there are wooden chocks holding it in a vertical position.

Underneath the mast, there is a metal plate (SS or ally??) with two vertical
plates welded to it. These verticals are either side of the mast, and a
bolt goes through the lot.
