Mike,
Danny's thru-bolt solution sounds good and the drilling, as he points out, will be the key to success. With the good amount of bolt you've got left above deck you may want to try removing it before you go to drilling it out, even though it may shear off. After a good soaking with penetrants (use some acid too, to attack the salts) you may be able to lock two nuts on top to screw it out. If or when that fails you could weld a short bolt of the same diameter to the broken end and use the new bolts hex head to turn. The welding heat may also help break the threads free. If still no joy,you're likely into drilling it out,. Here's a great link to using tread inserts after drilling out the bolt. https://racemagazine.com.au/cars/thread-repair-how-to-fix-broken-bolts-and-stripped-threads
Good luck with it,

Hi mike. I drilled mine out and put a bolt through. I now have a nut top and bottom
I  lost a lot of sweat and blunted several drills in the process. If you can get a cobalt drill they cut stainless much better than the standard. I didn't have one, as always I was fixing a boat in an exotic location.

As others may have experienced with removing the windlass from the deck, 3 of the 4 bolts were easily removed. The aft starboard bolt is threaded into the deck (no visible nut and probably into a glassed in steel plate). In fact in the bow locker there is rust stain coming through the fiberglass deck and also all along the hawse pipe.

 

In attempting removal the bolt head sheared off leaving a stud about 1” above the deck as pictured above (assuming picture goes with email. I am afraid that continuing to attempt to remove the remaining bole will simply result in shearing off at the deck line. My question is what have others done in this situation?

 

I can envision finding a coupling that could be used but would require an enlargement of the bolt hole in the windlass base thereby weakening it. The stud could be cut off and the windlass moved slightly with new holes for all bolts.

 

Thoughts?
