Load planning

Kayak capacity planner

Add your own weight to the gear you will carry and compare the total with a listing's stated maximum capacity. Arithmetic in pounds — nothing about stability, freeboard, performance or safety.

1. The listing's stated capacity

Copy the figure from the exact listing or manual. Some manufacturers also publish a lower usable capacity; use that one when it exists. This example value is illustrative, not a product claim.

2. Your load

Count everything that goes aboard: tackle, crate, cooler, battery, fish finder, anchor, flotation device, clothing and water. For a tandem, add both paddlers.

Your result

Margin below the stated capacity

Enter your figures and check the margin.

How to read the result

All inputs are pounds. Load = your weight + gear weight. Margin = stated capacity − load, also shown as a percentage of the stated capacity rounded to one decimal. The planner uses no hull geometry, no freeboard estimate and no performance band: it is arithmetic on the seller's own figure. A positive margin only means the load is below the number printed on the listing.

A stated maximum is a seller figure, not a stability or safe-load test. Manufacturers such as Old Town publish a separate usable capacity for people and gear that is lower than the maximum; when a manual gives that figure, plan against it. Water conditions, seating position and how the load is distributed are outside this tool.

Before choosing a fishing kayak

  1. Read the stated capacity, length, width and hull weight on the exact listing and in the manufacturer manual.
  2. Add your own weight to every piece of gear, including a battery or motor if the listing does not include them.
  3. Check whether the paddle, seat, pedal drive or motor is included or sold separately.
  4. Check the personal flotation device, registration and lighting rules of the U.S. Coast Guard and your state boating authority.

This tool answers an arithmetic question and nothing else. It does not establish that a kayak is stable, safe or suitable for any water; take those questions to the manufacturer manual and the authorities above.
