This can be expensive but it works. Remember not to over chum. Entice to fish to that boat but do not over feed them. After the chum slick is started, put a clam belly on your hook and let it drift out with you chum. It shouldn't take that long before you're hooked up.
Some anglers swear by live eels and they do work well.
Moriches Inlet is another great area to fish for striped bass. Orient Point is also well known. Many of the charter and party boats run special striped bass charters. The Prime Time III, the Nancy Ann and the Orient Star are some of the best. There have been many books written on this quarry.
