My Hus boat is too long to fit in our garage. We are building another one now, but how can I cover the?

opening of the garage and the boat, since I can't lower door. Leaving the boat outside is not an option, we tried it. It made a HUGE mess to clean up with all the pollen and chipmunks and birds. I must put something over the opening because rain runs down the hull and floods the garage and my laundry room. Help! Right now we have an ugly blue tarp over the opening and I think it looks terrible. The new garage will probably not be done for months. My Hus says "Who Cares?", but I'm worried about what the new neighbors think. What should I do?
