Never once were they shown wearing weapons. Much less armour. Or carrying anything they'd need on a potentially protracted search of an entire island for a long lost object. Water, food, blankets, A N Y T H I N G you'd take on an expedition. And I don't care if it's porn, you don't wear stiletto heels on a rolling ship, much less when you're going into a fight. Good luck *not* breaking your ankles. It's ridiculous. And no one, absolutely no one floats so that half their body is out of the water. We're mostly water in the first place, density wont allow it. Physics is still a thing.
