Lee, like Wally said, you need to read and be clear about the legal way to fish for lobster. Any commercially valuable critter like lobster is not something to casually go after. The fines are really large and the courts are not lenient unless you play exactly by the rules that the state has established.
And it applies to you and anyone that accompanies you. If your pal goes with you "just to watch" and ends up touching the line to the net helpfully, he gets a ticket too. Some things have some leeway, but market-value items like lobster don't.
