This will give you an idea of what needs to be done. One post is in regards to kayak storage, and how to store them. The second is in regards to winter storage.
My advice. Don't store the boat hull down. Don't put it in a place where it will get hit. Don't let snow sit on it, don't let water inside of it. Then you'll be fine.http://www.hobiecat.com/forums/viewtopic.php?f=21&t=12563http://www.hobiecat.com/forums/viewtopic.php?f=21&t=32883
