Usable weight capacity: what it means

Usable weight capacity is the self-bailing limit of the scuppers — the maximum load at which the kayak still drains water rather than taking it on. It's a more conservative number than total float capacity, and it's the one we publish.

Float capacity vs. usable capacity

Most kayak manufacturers publish a float capacity number. That's the load at which the boat would start sinking if it were a closed shell — useful for the spec sheet, less useful when you're rigging your boat.

Cajo publishes usable capacity instead — the load at which the scuppers still self-bail. Under that number, water that ends up in the cockpit (from chop, a wet PFD, a leaking cooler) drains out through the scupper holes. Over that number, the scuppers go underwater and the cockpit starts taking on water.

The practical difference is huge. A boat with 600 lbs of float capacity might only have 400 lbs of usable capacity — and 400 is the number an angler cares about, because that's the threshold for whether you're sitting in water or staying dry.

How it's measured

We measure usable capacity with the boat fully rigged out of the box — Horizon Pro Seat installed, Traverse Fatback Rudder System mounted, drain plug seated. The published number is what you have left to load onto a stock kayak.

You don't need to subtract the seat or rudder. They're already in the math.

What this means for rigging decisions

When you're adding electronics, a trolling motor, a battery, and a cooler, you're stacking against the usable number. Stay under it and the boat fishes the way it was designed to. Get within 50 lbs or so and you'll start to feel the freeboard drop and the boat ride lower in chop — still safe, still floating, just less margin.

The Outpost 128 (500 lbs) is the highest-capacity rigid in the lineup; the Terra 116 sits at 475; the Outpost 100 at 400.
