[Public-list] mast compression

[George Dinwiddie]

Patty,

461 is a new-style boat and has an aluminum beam rather than a wooden 
one.  There are two potential problems, however.

1. If the balsa core cabintop around the mast has gotten wet, it will 
rot and allow the cabintop to sink under the load.  The fix for that is 
to pull the mast and re-core the rotted deck.  Actually, I'd suggest 
making it solid glass under the mast, itself.  Use a foam core for other 
areas.  See http://alberg30.org/maintenance/HullDeck/DeckRepairs/ for 
more details.

2. If the inner liner is sagging, you need to cut an access hole in the 
vertical part at the door to the forepeak and glass in bulkheads under 
it for support.

Describe what you're seeing in more detail, and let's understand what 
you're dealing with.
