For optimal performance, a canoe should have a minimum of what dimension to avoid capsizing in rough water?

For optimal performance in rough water, freeboard is a critical dimension that refers to the distance between the waterline and the upper deck level of the canoe. Adequate freeboard ensures that the canoe has enough height from the water surface to prevent waves from splashing over the sides, which can lead to capsizing. A canoe with insufficient freeboard is more likely to take on water during turbulent conditions, compromising stability and safety.

While length, width, and volume are important factors in a canoe's overall design and performance, they do not specifically address the issue of water intrusion in rough conditions like freeboard does. Length can contribute to tracking and speed, width can enhance stability, and volume can affect load capacity, but it is the freeboard that provides a crucial buffer against waves, making it essential for maintaining upright stability when faced with challenging water.
