Re: drilling holes in a steel hull
I have done that too, but if you insert a bolt or shackel, paint cracks and rust begins. Now I use grease and tarr, the latter remaning elastic and stops the rust. On some holes, where I planned better, I drilled much bigger holes, Inserted a short piece of stainless pipe. I n some cases, I used a madrel to open the pipes and the flatten/rivet them in from both sides. Some of them I welded the pipe inserts with a TIG wlder, that being too much drama outside with wind blowing I use now 316 welding rods to do that. Then I paint, use a drilling machine to remove excessive paint from the inside of the holes. The welding with rods is now the easiest and gives the best balance between effort/performance.
Hope it is not too late.

PS. I have a gaff rig and some manila ropes and ash blocks, so a bit of grease and tarr dont matter, nothing like a holy t-shirt and some grease and tarr all over.
