Do you want a charter or a head boat? The charter will be more expensive as it will be just you and whomever you choose to go w/ you. A headboat is cheaper, as whoever shows up at the dock when it's time to depart gets to go.
My DH and his buddy charter the Lady Fran out of Barnegat Light, and have been going at least 2 times a year for about 10 years now. If the captain didn't find them fish, they wouldn't continue to go with him.
