Agreed. I didn't say you were obligated. What is said was that the more information you provide the greater your chances of getting volunteers. It's up to you to decide how much you want crew and how much you are willing to share in order to get that crew.
By the way, some of the "Chesapeake Lions" have a good bit of experience offshore. Just because we might live on and love the Chesapeake doesn't mean we don't leave her embrace. I'd sail with chef2sail any time and sleep well during his watch.
Good luck with your trip. I won't be in Beaufort until after the 22nd. Two trips elsewhere before that.
