There small reefs are all over close in. Try a poor mans dragger. Thick wire 3 prong claw on a mid. rope, strong enough to bend the wire, when you snag on the reef. If you need a drawing let me know. I take a 2" steel pipe put 8ga min. if I cant find thicker just add more hooks, drive a wood dowel in the pipe to hold the wire so they never come out and put a loop at the top for the rope. I make one wire long so I can bend it in half put it in the pipe then bend the two sides up so they are hooks and a loop at the other side for the rope.
Hope this helps.
