Another Welcome!
A VAST array of knowledge and expertise here, on all sorts of subjects.
Although my first lathe was a ML7 currently, Myfords do have premium, (in my view, somewhat unjustified, although fantastic work has been done on them)
Have a look at some of the newer far eastern machines, and F W I W, buy one a bit larger than you, at first, think you need. Buy from a reputable supplier, who will provide service and spares back up if required, and will try to solve any problems that you might encounter. There are hordes of folk on here who can help with advice, and if close enough, with practical help.
Purely my comment; would stainless steel be less liable to corrosion than bronze for your keel bolts?
Salt, plus dissimilar metals can cause some quite damaging corrosion, especially cuprous (copper/brass/bronze) and Aluminium alloys. (There are folk who are very much more knowledgeable on metallurgy, than I, around here)
