Its just struck me, you know, that I really haven't got that much idea what kit I should be wearing in what conditions. If there's ice about I get my hated dry suit out (or if I have't got the seals fixed don't sail!) but other than that I take a guess at how many layers I might like to have on and give up if I get cold... This really isn't a sensible approach for places bigger than my medium size reservoir and races longer than 40 mins, but I just hunted round a couple of clothing vendors websites, and there doesn't seem to be any info about what kit might be feasible for what degree of windchill... Now the science must surely be out there somewhere - there's been research on the subject for at least 60 years.
Will, I don't think what you were wearing would have been enough for me in those conditions, and I have, sadly, much better built in sub cutaneous insulation, but who knows? Peter, Roz, do you mind saying what kit you two were wearing? How did it work out, were you extremely cold, unbelievably cold or unspeakably cold?
And of course there's that nasty slippery slope where the energy lost in moving in clumsier clothing far exceeds any benefit in warmth... There ought to be some information available. I wonder if the RYA has done any research for the Olympic guys? Of course they may just adjust their sailing venue rather than clothing...
