Canoeing.com Definition: Lightweight inflatable vinyl or urethane floats displace water to provide increased buoyancy in rough water or submersions. Dump valves provide quick inflation and corner tie-in points make it easy to secure floats. Tapered floats fit bow and stern of solo canoes and pillow-shaped floats fit under seats and mid-ship in tandem canoes. Order a size slightly larger than the internal compartment to ensure a snug fit. Colors that reflect heat prevent expansion and possible bursting.
