By the way, I am a physician assistant. Do you think my skills would be of

value to the sailing community? Not to make money, just to contribute
skills.

The Peace Corps has groups in many of the pacific island countries. The usual
medical officer for each of these is a PA or NP. You might look into this as a
way to have a "base" for opereations while learning the local area and slowly
getting the lady into sailing.
The PA's I met there when I was a PCV (94-96) loved the assignment.
[ It pays well, also]
Good luck
