Plan within the manufacturer’s recommended capacity. Staying within that limit helps preserve safe handling, stability, and freeboard. This tool provides an estimate—always verify your kayak’s current manufacturer specifications and actual on-water load before launching. Hull stability, weight distribution, water conditions, weather, and manufacturer guidance still matter.
