What is the primary factor in capsizing risk for a kayak?

• A. Wind speed
• B. Temperature
• C. Wave height relative to kayak stability
• D. Boat speed

Answer: (C)

Capsize risk in a kayak is controlled by how much a wave can tip the boat before you can bring it back upright. The essential idea is wave height relative to the kayak’s stability. A hull has a stability profile: it feels solid at small heels, but as a wave heels the boat more, you must counteract with edging, bracing, and careful weight placement. When waves are tall or steep enough that the righting moment (the boat’s tendency to return upright) is exceeded by the tipping moment, capsize becomes likely. Wind and temperature can influence conditions—wind can make bigger waves, and temperature affects exposure—but they don’t determine tipping risk on their own. Speed can change how you meet waves, but the fundamental limit is set by the height of the waves relative to the boat’s stability.
