Basshunter gave good advice. What I would say differently is that when I fish montauk there are boulder fields everywhere.The goal is too keep the bucktail on the bottom but also at the same time keep it moving. Hope that makes sense to you. If you snag something, immediately let some slack in the line. See if the wave action will get you out. If not try to twang it and maybe you will be lucky. The best luck is that you make yourself, keep it moving so it never gets stuck. After a while you will get a feel for it.
