I was pretty amazed the ice cleared out of the water so fast. Lauched off 4th Ave with several other windsurfers as Centenial parking lot was closed due to ice.
As others said, good wind/waves but COLD water. I was out a couple of weeks ago in 6 deg air and little issue with the hands. I forgot to eat my orange (to see if citrus keeps the hands warmer). Yesterday I ate the orange but it was no solution when your hands are in the water. I think the drysuit keeps the body warmer so the hands are warmer - can't say for sure the same for the orange .
3.7 sail was overall a good call. I did notice a "lull" on iwindsurf which explains a couple of walks of shame. Could plane ok but I guess incoming tide, lightly powered and a few wave rides was enough to get me downwind. The wind did pick up and this was no longer an issue. Then it got near overpowered and called it a day. Good day but I was taking extra caution in this full on winter conditions.
