That four-inch freeboard situation is what a previous poster was describing for the "new" load-capacity rating of 1200 pounds (up from the older rating of 900 pounds), not your intended load of 750 pounds. I don't have experience carrying those kinds of loads in any tandem canoe, but I trust other's judgement that 750 pounds is a bit too much for safe and efficient travel in a 16-foot Camper.
