My question is: what would be a good choice for a weapon ?
I am not a drilled marksman so I guess I'll choose a shotgun, as the
yacht in the aforementioned story had chosen. When I google around a
bit this pump action Mossberg M590A1comes up pretty often. Together
with 00-rounds this would be a helpful combination I guess.

Why limit yourself to one? I'd have the shotgun for in close, but also
something with 'range'...just in case they stay a bit off and take pot shots
at you.
