One notch in the rail. No license required.
The original owner of my
boat (called Buckshee at the time) sunk a pirate
boat off of Venzuela back in the late 70's.
He peppered their
hull at the waterline with an old M2, put a few into their
engine and then left them there.
If you look real close you can still see the patches on the our
hull.
He had secret compartments all over the boat filled with various rifles and pistols.
