Kayaking Calculators

Free kayaking and paddling calculators.
Paddle length, hull speed, stroke rate, and trip planning tools.

Calculate the theoretical hull speed of your kayak from its waterline length. Understand why longer kayaks are faster and plan your paddling effort.

Calculate safe kayak load capacity. Check if your gear, body weight, and equipment fit within your kayak limits.

Find the right kayak paddle length for your height, kayak width, and paddling style. Avoid shoulder strain with the correct paddle size.

Calculate kayak speed from stroke rate and paddle length. Understand how stroke efficiency affects your paddling pace.

Calculate how tidal current affects your kayak speed and course. Find your actual speed over ground when paddling with or against a current.

Plan your kayaking trip. Calculate distance you can paddle in a given time at your cruising speed, accounting for breaks and tides.

Calculate the effect of wind on your kayak. Find headwind speed penalty and required extra effort to maintain pace.

Calculate calories burned kayaking. Accounts for paddling intensity, water conditions, and duration.
