It’s next to impossible to judge exactly how a marlin will react once it’s hooked. The one thing that’s certain is that there’s a massive fish with a spear on its face and anything can happen.
It’s not uncommon for fishermen to get speared by a marlin while fighting to get them in their boat. This particular encounter with a 400lb blue marlin nearly ends in tragedy as it leaps onto a fishing vessel, barely missing the guy who was reeling it in as it flies past him and onto the deck, nearly hitting the other guy on board in the process. Fortunately for these guys, this ended way better than the bloodbath it almost became.
