Abstract
Foam is sandwiched between baffles and two sheets of low friction enameled aluminum. The aluminum is bent to form waterproof seams between the sheets along the top edge and small runners along the bottom sheet. The body of the sled is shoulder width and narrow in depth to permit easy and rapid manual propulsion over ice and in water. All seams are riveted together, a top edge seam is a waterproof standing seam and the others are silicone treated for waterproofing. Side handles are secured to the body for carrying the sled. A hand-held combination ice grab and water paddle is secured to each side rail for propelling the sled. A front grasping rail is secured by protrusions from the front of the sled for the rescue. A harness cord with a snap hook at both ends is secured to the protrusions for harnessing the victim to the sled if necessary. A long tow line is attached to a rear hook.
