I have never seen them before, I found the picture using StumbleUpon. I would get one if I had a boat.I do like these and they have been out for a while. I was thinking of getting one for my Mom. If I had a boat bigger than a Kayak I would get one and an RV should have a bit more than this (in my opinion). Nice to point them out.
Open seas are anything goes. It is the shoreline that dictates Pro or anti gun and you can get in to a heap o trouble bringing guns in to port in the wrong country.I'm talking about attaching it to the anchor chain, forcing the tube to be underwater. Hey its just an idea. I hear that the the open seas aren't always the most gun-friendly places. Even though there is rampant piracy in some areas.
