Abstract: A cover for watercraft, such as pontoon boats, facilitates easy deployment and removal, as well as compact storage. The cover may be collapsed and deployed in a predetermined manner. The cover may include collapsible poles integrated with the cover fabric, which can be extended and retracted as the cover is deployed and collapsed. An arrangement of zippers and tensioners may be used to facilitate deployment securement and removal of the cover, as well as to facilitate access to at least a portion of the covered portion of watercraft while the cover is deployed.
