I own a mini max...just sold my paddlecat.
Hyside makes great boats, and they stand behind them.
My paddlecat spent like 6 winters rolled....no issues
My max is only 1.5 years old, so it has had only 1 winter rolled. No issues.
I store my boats in the summer and winter rolled in my garage in denver.
If the wrinkles become an structual issues as the boat is new, I am sure hyside will deal with it.
Enjoy your boat, have peace of mind...you bought a premium high quality boat, build by a manufacture with a strong customer support reputation.
Do not let those wrinkles give you worry wrinkles.
Rolling the boat for storage is a standard practice. .... just make sure boat is clean and dry before doing your end of season roll......wet rolls will not hurt the boat as long as it is unrolled and dried within a day or two.
