They have straps to tie them on you. You tie them together and hold them under the door. Or use any of the other crap floating in the ocean. Literally anything could be held in a shirt or pants. You can inflate your pants themselves by tying the legs together and blowing air into the waistband.
I imagine it would be quite difficult to tie knots with frozen limbs and fingers, in the dark. And trying to get a second person on the door would have required the already freezing girl to dip into the water. I can see why they wouldn’t try it.
