In 2003 the pay was for a FO 26k, co captain 44k, and first year captain 52k second year captain 60k. I think they don't pay the co captain that much anymore but I also heard that they actually got an increase in pay.
Living is expensive, crime is high, and on St. Croix there are hardly any tourists. They are all in St thomas or St john.
It is a great job to get your feet wet. Seaborne is a good local comapany with its normal ups and downs.
I did it for amost 3 years and had a great time.
Good luck
