Awesome. Large vessels are also high off water level so it will cause quite a bit of damage.
Yes. Until they wake up from childhood and send two or three boats to stand off and sweep the decks clear with automatic fire while the boarders are loading.
The only way to be safe now is to keep well supplied with arms and, when entering territorial waters, place them on a small boat to be kept offshore while docking.
I wrote as much here in another post.
