Red Dog in Sea Isle has boats with bimini tops which is good for getting out of the sun.
If you dont have a boat and you are renting one then the guys you rent from will give you the best info. Rent the boat and buy some bunker from them and they shopuld tell you where the crabs have been resently. On the way stop by the grocery store and pick up some chicken parts. Its good bait and cheaper than the bunker.
