Re: [Amel Yacht Owners] Windlass bolt to deck

whatever you do have a nut on top. Then it cant happen again. I drilled up from the bottom, there was too much bolt to go through from the top. This bolt is the critical one. Being through a plate attached to the hawse pipe it gives the strength to the attachment. Otherwise it is only the deck holding the winch and there would be considerable flexing under load leading to deck failure.

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.
