Look it up: swivel gun. Google should have a few pictures from maritime museums. Try to imagine the fun you could have with your own.
And it’s not just the owners of merchant ships passing the east coast of Africa who might appreciate a brace of ’em. Local boat owners who get sick of other people crowding them out in the marinas…or who are afflicted with saboteurs attacking their vessels while docked. Indeed, the Rottnest ferry would probably benefit as well.
The whalers and fishermen who are pestered by the Sea Shepherd gangsters would also appreciate the devices…after all the maritime nuisances do have a skull and crossbones as a symbol and I think that makes them fair and traditional game for a charge of canister over the taffrail.
For myself, as I do not own a boat, I would settle for just the one…mounted on the driver’s side door of my Suzuki Swift with a friction primer and the lanyard led inside through the window. I would use it in our local shopping centre car park for the drivers who loom up and menace you when you are trying to carefully back in or out. I would not be too mean…perhaps load it with Jaffas instead of grapeshot.
If it’s good enough for Johnny Depp and Geoffry Rush, it’s good enough for me.
