Squid boats have trouble with this for people- you can die on them, it’s not too common with life vests, but it was an issue back in the day- but without a boat/other crew on hand, in a small setup like this? You’d honestly be fucked if it went south. Also, certain types of squids hunt in packs, and some have been known to attack humans- if you’re in the water and they’re going nuts for the light, you’re more at risk.
It was one of the most beautiful things I’ve ever seen. They truly dance underwater. Once you lift your head out of the water you just hear tons of screams and people choking on the choppy seas and it vaguely feels like you’re one of the survivors of the titanic but as soon as you put your head back under that water… pure fucking magic of the sea.
