On either one, would one get to choose to have the yacht for, say, July and August each year (if they paid the neccesary costs)?

I am 16 years old and would like to work on a yacht over the summer. Am i old enough?

I wanted to do something different so after brainstorming , we came up with the idea of having my party on a yacht. Approximately 30 guests.
I live in Los Angeles.
Need it for about 8 hours ( day hours preferably)

please help…BDay is in June!

Is there a minimum age to be a steward on a yacht? 18, 21? anything?
