Don't own an Allison boat yet. Am working my way through the required number of posts that new forum members do. Where I am from (Northern Utah) I live over a mile above sea level and in the winter it gets well below zero. Have not seen a single Allison hull in my state and I have been here for over 40 years. The fiberglass hull boat I have got a lot of crazing in the gelcoat from the cold weather during its first winter, in the metalflake portion on flat top surfaces, stored outside under a high quality custom cloth cover. The white gelcoat down the sides and bottom of the boat are unaffected, just the metalflake. It gets down to as low a 25 below in the winter, average low in my mountain valley is around 10-15 degrees for three months. I can put up a shelter over the boat for the cold time to keep the snow off, the boat will not be garage kept, mine is too short for a 20 or 21 footer. I have a fair amount of experience winterizing motors from working in a boat dealership a half lifetime ago. Do any owners have their boats in places where it get really cold in the off season and if so how has the gelcoat held up? I don't want to put a lot of cash (for me) into something that the cold weather will damage quickly. I might well live in a place and house situation where I'm better off getting an aluminum hull. I don't mind getting bad news to avoid a poor decision that would cause resale value to quickly plummet. Thanks in advance for your response(s).
