If I were you I would take a drive and introduce yourself in person. There are many boats along the bay from OC to Cape May, take a phone book with you.
I'll be honest with you, I tried to do what you are doing over the last couple of summers, you probably want to look for something else. First mate, no chance. They have guys that work all year with them. 2nd or 3rd(if you get on a party boat) if you are lucky.
Dont even think about workin on a party boat. BORING! Go down to SJ marina in a few weeks and just start poundin the dock. Somebody will pick you up if you show alot of interest. Doesnt matter much about your experience, alot of guys prefer to have new guys so that they can teach them their way. You better really love fishin, cause it isnt for everybody. I know one FULL TIME charter boat that is lookin for a guy right now. Email me.
