First sailing in 2009 for me, we had 55 deg F air and 40 deg F water, nice sunshine so we were warm the whole time.
Mark W. joined me for some great mid-February sailing, the gusts turned the water to liquid smoke, they were in the 40 knot range. Most of the time we had nice 25 to 30 knots, perfect 4.2 sailing on my 84 liter Cross.
