You could start right here. However, you should present a little information about yourself, like any sailing experience you have, when you would be available, some personal informatiion of at least a telephone number to exchange conversation.
How old, what sex, would you travel to meet the boat
, are you willing to familiarize yourself by going for a test sail? List attributes you can give to the success of a pleasant sail, etc.
I say this really, not only for you, but for anyone wishing to crew on any boat
After all, both the captain
or owner and you; should make certain you have the details and expectations worked out before you set sail..
