Don't know if you are in Utila or Roatan, There's a cruisers net in Roatan, go down to west end and find a cruiser, look for their dinks and wait. I cant imagine they would not put word on their net for you. A lot of boats back and forth from the Rio Dulce.
You might even come across folks venturing further afield.
Utila has less cruisers but take the same approach.
It's likely you will get a response from folks down there.
or, do what I did years back...
Bought a 25 ft hunter
in Utila, lived aboard and learnt to sail (really, it aint hard)
I owned her for about two years and then moved on to a bigger boat
I had two three hr sailing lessons
when I bought the hunter
, that was nearly 20 years ago. I have covered some ground since then.
You dont need pieces of paper given to you to know or learn how to sail. If you do, stay off the ocean. Put the money
you would pay for a course towards your own boat
. Start small and work
You could check out Ceiba, even Porta cortez navy
yard for a boat to purchase
Just my advice. No, not arguing with anyone, not interested,
Best of luck
