I think compressed air is the way to go, something like the air brakes on an 18-wheeler.
Small holes in the hull, big push, big bubbles, scare the hell outta the fish!
Also, with good air pressure you could hook up a real air horn, just to let folks know that the village idiot -- oops, marina idiot -- is trying his hand at docking....again :-)
