The Seaborne guys seemed cool when I was down there. Nice deal. If your really are just dying to get to an island down there, then there is plenty of places always looking for a pilot, that would humor the time building pilot.

Theres so many places down there, not to mention the 50$ first class medicals. Just bum around for a week, if you cant get a job, I dont know what to tell you.

As far as the transition deal, probably true, but its a job you stay at, its not for turbine time, Its a good job. All day time flying. The did practice the ILS in STX when I was there, to a missed of course.
