The 17' Classic Aluminum Canoe is manufactured out of aircraft aluminum and heat treated in order to harden it for additional strength. These are produced in several thicknesses.
The toughest of course is the .050 gauge canoe and it is for high use or whitewater situations, but the 84lb weight is to be a consideration.
The canoe has stretch formed sponsons on the sides above the water line. These "safety foils" effectively give the canoe a wider profile for extra stability while keeping the streamlined profile during normal paddling.
