Let your boat stay dry in all weather conditions by storing it inside a 30-foot wide round canopy. Designed with a polyethylene cover and galvanized steel frame, a round 30-foot wide boat canopy withstands the elements for several months at a time. Once anchored into the ground, the shelter provides a high level of strength against a range of everyday and unusual weather, while the cover protects your vehicle from harmful water and UV ray exposure. To keep your vehicle dry and prevent it from getting damaged from long-term exposure to the elements, store it inside a 30-foot wide round boat canopy.
