Of Course!
We sail out of Elliott Bay in Seattle, but live in Ellensburg, WA. The temp in Ellensburg is often twenty degrees colder then what it is in Seattle, so it ALMOST balmy for us. Course we are used to wearing long johns, woolies, turtle necks, gloves, knit hats, heavy wool socks, sweaters etc. So we just layer it on when under sail and have the diesel furnace going down below. We take turns on deck (hour on, hour off). The main thing is we love to sail and love being on the water. And if its blowing or raining too hard, then its time to pull up to a dock, visit the local pub and enjoy the good brew, good food and local atmosphere.
