Much as I love Indonesia (and I know it from living and sailing there as a young lad, and from later visits), it's just about the last place in the world I'd go to buy a "bargain" boat. Unless, perhaps, it was my intention to spend several years sailing in the Far East.
Indonesia is 10,000 miles away. Getting the boat home to
California is going to cost a small fortune, no matter how you do it.
You don't know the condition of the boat with any certainty, quite irrespective of "language problems". The only way to know is to travel there with your three surveyors (for a boat
survey, a
rigging survey, and an
engine survey). Licensing and
documentation, and other official paperworks could well be a nightmare.
Now, if you're REALLY looking for an exotic adventure....
And, you're ready to spend about twice the
money you think you are....
And, you want tales to tell your
children and grandchildren for the next 30 years....
Then, by all means, go for it :-)
