How Much Water Does A Canoe Need To Float?

Canoes need one or two types of flotation to float, depending on the perceived risk of taking on water and the consequences. High rockered canoes displace less water towards the ends, drawing more water amidships than similar size boats with less rocker. In most cases, 5 inches of flotation is needed.

Canoe floats are popular recreational activities that involve floating down rivers or streams in a canoe. Tying float bags in the stern and bow of the canoe is essential when going to canoe in whitewater or rapids to prevent the canoe from sinking in case it flips over. According to USCG regulations, all canoes must have enough floatation to keep them afloat even when completely filled with water. Most canoes require a water depth of at least 1 to 1.5 times the length of the kayaker’s or paddles to safely kayak or canoe without hitting the bottom.

The canoe’s large volume, 12-13m long and about 0.5-1m deep, makes its density small enough to float on water. A general guideline is to have a water depth that is at least 1 to 1.5 times the length of the kayaker’s or paddles to safely kayak or canoe without hitting the bottom.

A canoe can hold 300 gallons or so of water if fully swamped, but the amount of energy needed to remove that water with bailers or a hand pump is approximately 8 lbs. Solo canoes weigh around 32-56 lbs, and 4-7 gal of air is needed to keep the hull from sinking.

The weight of the water displaced by the boat depends on the size of the boat, but it must float. A light weight boat of 300 pounds displacement with 100% flotation requires 4.8 cubic feet of foam that weighs 2 to 3 pounds per cubic foot.
