How We Research and Size

The sizing math

Paddle board volume uses litres per kilogram of total load (2.0 beginner, 1.6 intermediate, 1.25 advanced). Kayak capacity uses the 70 percent performance rule: total load divided by 0.7. Kayak paddle length follows width-by-height sizing tables; stand up paddle length is height plus a discipline offset. Life jackets follow U.S. Coast Guard weight classes for children and chest bands for adults. Every chart and long-tail page is computed by the same functions as the calculators.

How products are chosen

Every product comes from a live Amazon listing with a real price and photo. Specifications shown are only those the listing states outright. Picks are made from specifications, capacity ratings, construction and verified owner reviews. We have not tested these products in person.

Prices

Prices are captured at our last check and change often. The listing is the final word.
