Don't know about fines, but I can tell you that if you fire up the boat at Hemmingways after lunch and head over to look at the anchored missle destroyer running dead toward it at about 40 mph it will draw the zodiac with the 50 cal on the bow from around the back of the destroyer to take a look at you.
We turned to parallel the boat and dropped down the speed well away (I'd already read of the 'safe' zones, and had an academy navigation instructor, my neighbor, on board with me). Still, bet it got the attention of the ships watch crew
