Prolonged cold's (+5*C to -25*C) effect on carbon skis

Dear forum members,

I have a carbon-kevlar surfski from Nelo (WWR construction) and a full carbon slalom kayak, which I may be forced to store in an old ship container on-land for the winter.

Our winters are generally around -10*C to 0*C, with a few weeks of -15*C and a few day of -25*C.

Do You think it poses a danger to the integrity of the materials or the seams? Should I definitely get them inside? Really interested in your thoughts! Thanks!!

I've kept my fiberglass, Kevlar and carbon fiber canoes in an unheated garage during the winter in the northeast, upstate New York , where it regularly gets down to -25 degrees Fahrenheit and never had an issue. Plastic might have an issue if you flexed it when it was frozen, but never had an issue with those either.

This has been discussed a lot on other forums, and the consensus is that composite boats have very little to worry about, temperature wise at least.
Plastic boats can cold-crack because plastic has a different rate of contraction/expansion vs aluminum or wood, but this is mostly applicable to north american open canoes which have gunwales made from a different material than the boat. Since most skis are single material (meaning composite/wood/metal. Obviously the composite group covers different cloths)

I have a SR advantage as well as 2 kevlar american canoes that are stored in an unheated garage with no ill effects at colder temps, down to -10ish Fahrenheit

I'd say you should be fine.
