[Alberg30] mast compression

[cbcurrier at spinrx.com]

Actually Ian, what you have is a rotten deck core. There is a period
of dime during which whitby cored all of their decks with balsa.  This balsa 
over time has deterioriated and as with you mast you actually see a bit of a 
divot or dent where it sits.  I bet if you wals around on the deck another 
person can see it move under you. This suggests you need to recore the deck.  
A discussion that has been going on around here a bit lately.

You do not need to worry about that mast beam ... it is likely in great shape. 
your problem is from the top down.  In particular one solution has been to 
build up a thick layer of epoxy under the mast step to replace the rotten or 
nonexistant balsa. This is probably better explained by those that have done 
it.  I am working on it. Good luck.
