Without knowing how representative the 18 shipwrecks they picked are, it’s hard to know whether their conclusions are widely applicable. Also, from their research paper, some of the ships they mentioned had been torpedoed or ran aground, SIX collisions, etc. A first guess would be that men sometimes survive more than women and children simply because they were more physically able to overcome the dangerous environment. If a group of average men and average women are thrown into the ocean and left to their own devices, after a few hours more men will be left just because of physical strength. Nothing to do with sexism. Also, it seems like the authors are going out of their way to say that chivalry actually doesn’t happen much, that men didn’t want to help women, etc, so that makes me think they have an agenda and I’m less likely to believe their conclusions that are counter to my intuition and experience.

  I didn’t know so I looked it up. Looks like more body fat compared to body size is the key, regardless of gender. > [1] No significant gender differences in total metabolic heat production normalized for body mass or surface area were found among subjects who completed 90 min of immersion (9 women and 7 men). Nor was there a gender difference in the overall percent contribution ( approximately 60%) of fat oxidation to total heat production.…On the basis of the above findings, we accept the first hypothesis that women and men exhibit similar changes in body cooling and M˙ during cold water immersion at rest when subject responses are corrected for BF and size.

  Even if so, that's just the temperature problem. There's also the possible problems of: * needing to swim for a long time, regardless of the water's temperature (this is what I had in mind with my comment you replied to) * pushing your way past obstacles in a damaged ship * physically surviving damage from falling debris, burns, cuts, blood loss I'm sure others can think of more issues.
