Mass Hot Tub

I live in western Massachusetts I also have a similar leak from the pivot sides of my new heavy duty cover where it forms ice cycles constantly during cold weather. The same condition existed with the last cover with my Jucuzzi tub? I have yet to find a solution? Is there a cover that solves this condition? I keep my tub at 102 year round and ice cycles abound in the winter as well as gradual water loss!
