Try contacting some of the companies that make davits and ask if they
have ever made davits for your model boat and maybe they have a
data base of davits.
Like ocean Marine maybe because they make davits for lots of hunters or Kato
or some others.
You could look around at other boats how it's done and get idea's or come look at my davits on my 36 which has stern rail seats and similar stern maybe.
