A mooring cover is used to keep sun and weather off your boat during the boating season. Covers are made from Sunbrella, Solarfix UV marine grade thread and normally snap onto the gunwale perimeter. Pricing assumes the boat is brought to Robie Canvas for patterning and installation. Extra height due to large towers or other structure on the boat that needs to be covered, cutouts, any snap stud installation on the boat, and any travel required by Robie Canvas is extra.
