Wow, climbing ontop of that thing and banging on the hatch takes some fuckin BALLS.

Props to this guy for being a badass

Damn soldiers, you scary!

What was he yelling by the way?

"Hodor day porto!"

I hear "Alto su barco...Alto su barco ahora"

Poor Spanish for...
High (or upward?) your boat...High (or upward?) your boat now. (Telling them to surface)

There's also a good chance he was trying to say "stop your boat...Stop your boat now"....Alto is what's on Mexican stop signs....but as a noun.

Alto is not a verb from my recollection.

While "Alto" does mean "High", it also means "Halt", and his Spanish is acceptable for "Stop (halt) your boat". "Pare su barco" or "De en alto su barco" (or embarcacion, given it's not technically a boat...) would have been better, but who cares...

Technically not as a verb....at least not from what I recall and also looked up online.
"Alto" does mean stop, halt, or standstill, but in noun form as in "this is the right stop" or "traffic is at a standstill", not verb form like "stop the boat".
Still, it was understandable pigeon Spanish, so I agree, who cares?

His Spanish sounded OK to me. According to wordreference it does mean stop as in the sense of halt right there!:
