The ice and snow sailing season here in Saskatoon starts the first week in November
and lasts until mid-April. We often sail in temperatures down to -20C. The only
sail problem that I've experienced is with the vinyl windows. The windows have a
tendency to blow out at temperatures below about -10C. In 5 years of ice and snow
sailing I have blown out two windows.
The windows can endure lower temperatures if the sun is out. So can I. If the
window sounds like aluminum foil when shaken, it will likely blow out when you sail
it. Covering the entire window with duct tape may prevent blow out. If you leave
a small area uncovered, however, the small area will blow out.
Monofilm appears to be more durable at low temperatures but there are few data
available. The sail manufacturers either don't know or don't care.
My solution is to use old cloth sails that are expendable. They are a dime a
dozen and you can still sail 3 times faster than the wind speed.
Moreover, if you can run a sewing machine you can replace a vinyl window in less
than 30 minutes.
