Thank you Charles Cook and John R. Pollard for your replies.
Not sure what is meant by "super cargo"?
The skipper is the owner of the vessel. He plans on sailing to Scotland and then later sailing back to the Carribean. I am planning on flying home from Scotland. I may stay in Scotland and get a rail pass and tour.
I will be required to stand watch. Four hours on fours hours off. I did ask about skipping watches and the captain said if it is necessary yes.
The cook is a cordon bleu chef so I wasn't asked to cook.
Didn't even think about "cleaning" so not sure about that.
Thanks for the advice regarding shared cost of food.
And the idea of an accredited school vs. just a captain giving advice/lessons.
