[Rhodes22-list] Compression Post

[Peter Nyberg]

Patrick,

I’m quite sure that my compression post is not directly under my mast.  From recollection, I’d say it’s a couple of inches to port.

There should definitely be support directly under the compression post all the way down to the keel.  I’m pretty sure that when General Boats recycled my boat in 2016, all of the support structures under the floors were redone. All of the new support material was either fiberglass or pressure treated wood.  I think experience has shown that untreated wood will not last in this application.  I think the King Starboard material that Cary mentions would be a good choice as well.
