So if I understand this correctly, you would like your crew to pay their own transportation to and from your boat, pay for their own provisions while helping you sail your boat, pay their own immigration fees, et al so you can get you and your boat where you would would like to go?

paint and I'll help you sail to Panama. How's that for a equal deal?
