Yacht Engineer - The Role and the Path?

The easiest and quickest would be to be friend an Owner or Captain and have them give you a job as engineer. This would not however necessarily be the best as believe it or not there is a lot more to being an engineer on a yacht than many who are not simply cannot appreciate.

I would say the merchant navy is a very good way to get into it, if you are good at and enjoy the academic work you can go onto university degrees from that if you so wish.
