I know this is a question that doesnt have an good easy answer, but if you were certified how much could you expect to make in an entry level position? I am just curious.
Life is not good in the paid crew world just now. There are highly qualified crew working just for their keep with zero salary.
However if you have a sailing partner WHO CAN COOK then there are some temporary posts around for couples with the charter companies who want skipper/cook combinations to take charterers out when they do not have sufficient experience to look after themselves.
The Moorings is one such company who employ skipper/cook combinations and who pay them reliably.
