A mooring cover is the perfect solution for boaters who want to leave their boat in the water and keep it covered. These covers are quick and easy to install and have an elasticized hem to hold the cover in place. There are also loops around the hem to allow for the attachment of weights or suction cups to hold the cover in place. Ropes may also be used to help anchor the cover. https://www.nationalboatcovers.com/c/boat-covers/mooring--covers.html
