I've sailed in low forty water temps and air temps of 26 f with crew. I was only about a thirty minute sail as the lines froze and recall pushing the boom out with my feet. I wore two wet suits, I was warm, but hardly comfortable. I never tipped, but when we came back to shore. I remember going out to waist deep water, just to see how it felt. I had a small one inch gap between my booties and my wet suit. I got an ice cream headache in my lower leg within 5 minutes. It really made me think, it wasn't a great idea. I was lucky I didn't get in trouble, adreneline probably would save me for a little while, but that was cold to the core and you would eventually lose your faculties. I'd rather die launching off a wave into the mouth of a killer whale than freezing to death.
