What do you think @cryptofarmer? I'm not too fond of the idea of swimming out to the boat, but if you want to try, I can cover you with my pistol (if you give me some bullets, cause my pistol is empty. Otherwise I can just point my pistol at them and yell PEW! PEW!, that should scare them).
I'd choose option 3 even before reading your comment. I love to swim and I'm curious to see what I can find on the boat. Of course I'll give you the 11 bullets I have - now that we are a team, what is mine is yours! :-) Please cover me from cannibals!
