Outdoor winter storage of boards

[U2U2U2]

I don't think you need any further precautions.

Blankets... Heat blankies...

Don't bother with the blankets. Without a heat source inside them, the board's gonna do the same with or without them.

And even more if it's hot, because that's when the water vapor blows it up like a balloon.

Some plastics crack easily or shatter when impacted in very cold temps. Maybe the AST skin is vulnerable? Just don't try snowboarding or tobogganing with it.

Where I live the lowest temperature in January was -12 F (-24 C). I store 4 of my boards outside on an open trailer under an ordinary plastic tarp which keeps off the snow. I've stored boards outside in the same conditions for more than 15 years.

Years ago I saw a Windsurfer that had substantial skin cracks & skin breakage from being stored outside. I think a key difference between that Windsurfer and my boards is sun exposure which I believe created temperature differences on the Windsurfer that led to the skin cracking during quite cold days. Obviously, that is just an uneducated guess. Still, my boards have not visibly suffered from being outside all the time in an environment which has about 10 days a year of below 0 F and about 10 days a year of 90 F or above.

Has anyone verified whether the Bic warning referred to 0 F or 0 C?

Two educated guesses: It means 0 C because ...
That's what the rest of the world uses, and
'That actually matters to water, whereas 0 F is an arbitrary number in a continuum to water.

Just curious - which Bic Wind SUP did you get?
What sail(s) are you planning to use with it?
