[IC27A] broken bow cleat bolts

[donslevin51]

one of the bolts holding my port bow cleat has snapped.  It appears that the 
cleat is so outboard that it may be part of the hull/deck joint.  I can't find 
access to the nut as it seems to be through-bolted.  I have not been able to 
find access to the nut to replace the bolt.
I haven't completely taken apart the V berth and there is a flimsy bulkhead at 
the upper forward compartment.  Has anyone had to replace a bow cleat bolt and 
how was it done?
