Yes it is that time of year again! I was re-reading this article
by Chris Rossi and wanted to see if there is any more of a consensus now days. I agree with everything Chris has to say even if I can't wrap my head around a few things. What we do know as fact is that as the water cools it becomes more dense and the viscosity increases. I have read that the increase in density is very minimal and the main thing you will notice as the water cools is the increased in drag due to the increased viscosity. The one thing I hate to hear each fall is that cold water is fast, fluid dynamics proves this false. I think the reason people come to the conclusion that cold water is fast is because the increased drag on the ski as the water cools causes you to come into the buoy narrow which makes it feel fast.
