Every question, answered.

It sinks — no float built in, and it's worth knowing that up front. Soaking it in the wet footwell, in rain, or under paddle drip all day is completely fine, and it rinses clean afterward. But send it over the rail into open water and it's gone for good, the same as anything else that goes over on a kayak. Keep it low in the cockpit and it's not something you have to think about.

That's specifically what the wide base is built for. It bridges the tilt of a smooth polyethylene deck instead of standing on one point of it, and the fins keep a bottle from working loose as the hull rocks. Tip it with a lean or a wake and it settles back level on its own.

The 32 oz wide-mouth is the one honest miss — its base runs about 3.5 inches, past the top of the roughly 2-to-3-inch range that settles in. A narrower bottle, a can, or the 40 oz tumbler all fit; the classic paddling Nalgene is the exception.

It fits — the base lands comfortably inside the range, and it's the container most of this audience already carries to the water.

No. It doesn't clamp to a cockpit rim like the sit-inside holders or bolt into a gear track like the fishing-kayak mounts. It sits loose on the deck or the footwell floor and works on either hull style.

Not for this. Sit-on-top decks are built to get wet and stay wet, and this holds up the same way — soaking, spray, and standing water in the footwell don't bother it. The overboard rule above is the only water it minds.

That's the normal condition it's built for, not an exception. The base flexes with the tilt and brings the drink back level as a wake rolls under the hull. It resists tipping through that kind of rock — a hard broadside hit is still a hard broadside hit, same as it would be for anything riding loose on deck.

Both. It sits on the cockpit floor or the flat deck the same way either style — no sprayskirt to pop, no bungee to work it loose from, nothing specific to a sit-on-top's molded recess.

Rinse it at the take-out or run it through the dishwasher at home. It's one piece of solid flexible material with no seams or hinges for grit to hide in.

The base is called the Steadi. It's molded in small runs in Orange, California by Steadi Labs — veteran-founded, patent pending — and it ships free from steadilabs.com, with 30 days to decide if it's earned a permanent spot in the cockpit.

Yes — a standard 12 oz can runs about 2.6 inches across the base, comfortably inside the 2-to-3-inch range this settles into, but a can that light gets top-heavy fast as it empties, which is exactly what the shallow molded deck recess loses first in chop. The fins close around that base the same way they would a tumbler's, so a half-empty can gets the same grip a full one does.

Most tandem paddlers run one per seat — one near the bow paddler, one near the stern. Each base sits loose on the deck or footwell rather than mounted to a fixed point, so there's nothing to share or reposition mid-paddle. For a group outing, that works out to one per paddler who wants a drink within reach, the same as any other piece of loose gear in the boat.

It comes in colors built around the water — River Stone, Reed, Whitewater, Sunrise, Deep Channel, Flat Water, Sunset, and Sandbar — and there's nothing to size or fit to a specific kayak model, so it works whichever hull the gift ends up in. It ships free and is molded in small runs in Orange, California, the same as any order.

It's one piece of solid flexible material, with no clamp hardware, hinges, or seams for grit and sand to work into over repeated trips. There's nothing to corrode from repeated wetting the way a metal cockpit-rim clamp or gear-track hardware can, and nothing that needs re-seating the way a suction cup does after a season in the sun.

No — it isn't insulation and doesn't claim to be. It holds whatever's already in your hand steady in the boat; a thermos, an insulated tumbler, or a can handles the actual temperature. Its job is keeping what you brought upright through the paddle, not changing what's inside it.

A clamp-on rim holder caps out around 20 ounces and needs a cockpit rim — a coaming — to clamp to in the first place, which rules out most sit-on-tops. This has no capacity ceiling tied to a clamp: the fins flex to seat bases as wide as 3.15 inches, which is why a Stanley 40 oz H2.0 FlowState Quencher (base 3.1 inches) fits, and it sits loose on the deck or footwell of either hull style, no coaming required.

Yes — it isn't sized to a specific hull. It sits loose on whatever flat deck or footwell space the boat has, whether that's a short recreational kayak or a longer fishing model rigged with a gear track it doesn't need.

No — since nothing clamps, bolts, or mounts to the hull, it isn't tied to one boat. It rides along in a dry bag or the console and moves to whatever kayak you're in that day, rental or otherwise.
