I don't need a skipper, I have my sailing license!
You are the captain of this yacht, you are free to go wherever you want and this route definitely is going to be full of undiscovered bays. No extra costs for a skipper, it's cheaper and you are only with your friends. Have fun and enjoy your holidays!
Bareboat or skippered boat?
Still don't know if you need him? WIth sailing license you can rent a yacht without a skipper, in case you don't have it the skipper is an obligatory member of your crew.
