Technically, a woman would be more suited to working on a ship's deck anyway - a lower center of gravity makes 'em more stable in high sea states.
Plus, whereas men have greater upper body strength, women's endurance has been shown to be greater than men's. So there are swings and roundabouts.
I just think that the whole argument about women being so disruptive to men in the military due to the distraction of sex is a childish one. I mean these folks are supposed to be tough and professional. If the mere presence of a woman can turn hardened professionals into sappy incompetents, I think there's a deep flaw in military training.
