[Rhodes22-list] Demasting

John:  I agree with the inadequacy.  The bolt pulled out without any damage to deck even leaving the mastic which surrounded the bolt in the hole.  The washer and nut were in the anchor line box.

Clearly attaching the forestay in that manner was dangerously  

inadequate.  That part of the deck is not reinforced to handle the  

loads generated by a full jib under sail.

Since your boat seems to have something different about the anchor  

installation, you need to consider two alternatives:

1) Remove the anchor and mount it in some other fashion so the  

forestay and can be attached to a bow-mounted chainplate and secured  

properly.

2) Barring that, you should reinforce under the deck where the bolt  

passes thru with some stiff marine plywood or a chainplate and use one  

or two big, wide fender washers under the nut to spread the load out.   

Even so, I'd be cautious about that solution since the deck wasn't  

designed to do that.  You also have a nice hole to leak into the  

forepeak and deck core... sealing will be critical.

Come to think of it... that may be why the rig failed!  Water leaking  

thru that mounting hole softened the deck core and allowed the washer  

and nut to be pulled straight thru.  Better check that area carefully  

and repair the deck core as necessary.

Cheers!
