Your reply to Paul, indicated that it was set up to dive/charter. Can I assume that you seek to use her Professionally or will it be just your personal pleasure
Note: just reviewing the above sound somewhat salacious...but you get the drift.
The former will require considerable effort the latter join one of the many sailing clubs that are dotted around the island and you will with the experience you note regarding creel boats quickly achieve their "Patron" qualification
Finally as a Scot from Edinburgh where were you based in Scotland
Best Regards and welcome
