Canoeing.com Definition: Waterproof or water resistant covers provide protection from rain and waves. Made of neoprene or coated nylon, should fasten snugly below gunwales on canoe exterior. Basic, lightweight designs commonly Velcro to canoe and protect from rain and splashes – ideal for cold weather and cold water paddling. Heavier, more substantial designs attach more securely with snap-on or ladderlock systems and are best for whitewater paddling and rougher water. Skirt openings may be unfitted or fitted to the paddler with shock cords, adjustable compression straps or Velcro. Fitted skirts should be easy to undo, providing quick exit from canoe when needed. Available in 1, 2, and 3-piece attachments.
