Make them pay

Maybe if they started to REALLY inconvenience these "poachers" by dragging their boats to the docks while they do their thing.
If you knew that you were going to lose at least a half hour on top of a fine, you might think twice about it.

Just do what I do.
Cast over their line and steal their lure.
If they can beat my 65# samuri they can keep my cheap diamond jig.

From what i've seen it seems to depend on the mood. Somedays they just yell at them over the pa and then other times they chase and board them. Honestly I don't think they care. I watched a boat fish under the sag one day, even getting with in feet of the impoundment and casting at it. If they were terrorist looking to place a bomb on the bridge they would have gotten away with it. Boats troll for hours by the dolphins and no one comes out the marina to do anything. I have a ton of pictures of boats fishing the canal, I even have pictures of the tug boat and barge guys fishing and trolling the canal
