[Rhodes22-list] Compression Repair and Addition of Compression Post

[Andrew Collins]

David

You are correct. Our boat's respective deflections are opposite. The problem
I have is if I move the compression post you can't get to the head very
well, so I am thinking of installing a stainless steel bracket with a
buttress that will catch the mast step forward and the compression post aft.
The diagonal member would only be about 8-10" long. I know a custom
stainless fabricator and can't imagine it would be expensive,
$100-150<$@2100-150>,
maybe.

The other possibility is to get the SS comp post from Stan and install it at
the aft end of the V berth. To do this I would want to take it down to the
hull/stringers and glass it in. Then the deck reamining between the 2
hatches must act as a bridge. My deck is wood cored, so my SWAG (scientific
wild ass guesstimate) is that it will be OK.

I guess a call to Stan is in order. I'll keep da list posted
