Every question, answered.

It sinks — plainly, no float built in. Soaking it in bilge water, rain, or a splash over the side is completely fine, and it rinses clean. But if it goes over the gunwale into the lake itself, treat it like your keys: gone. Keep it low in the boat and you likely never have to think about it again.

Yes — that's specifically what the wide base is for. It bridges the arch of the hull floor instead of resting on one point of the curve, and the fins keep a cup from migrating toward the centerline as the boat rocks. Tip the hull and the base rights the drink again on its own.

Stand it up and look at the bottom, not the rim — tumblers taper and bottle necks narrow, so the base is the only measurement that matters. Anywhere from 2 to 3 inches across settles in; the 40-oz Stanley is on the fitting end of that range.

The 32-oz wide-mouth is the one honest miss — its base runs about 3.5 inches, wider than the 2-to-3-inch range that settles in. A narrower bottle, a can, or the 40-oz Stanley all fit; the wide-mouth Nalgene is the trip staple that doesn't.

Most bottle-shaped thermoses fit inside the range. A travel mug works too as long as it doesn't have a handle — handled versions run into the same problem enamel camp mugs do: the base fits, but the handle sits where a fin needs to grip.

Nothing clamps, bolts, or ties to the hull — it isn't that kind of holder. It rests loose on the floor of the boat, so there's no jaws to size to your rail and nothing to strip off before the portage.

Movement is the normal condition here, not the exception. The base flexes with each tilt and brings the drink back level as the boat rocks through a wake. A paddle stroke or a passing wake, it settles back from; a direct hit from a gunwale bump is a harder ask, same as it would be for anything else riding loose in the boat.

The Boundary Waters bans cans and glass bottles for food and drink — that's a rule about what you pour into, not what holds it. The base isn't a container, so it works the same everywhere in the wilderness; bring your drinks the way BWCA already requires and set them in the base as usual.

Dunk it and swirl it in the lake before you load the car, or run it through the dishwasher once you're home. It's a single piece of solid flexible material — no seams, no hinges, nowhere for sand or grit to hide.

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 it's earned a permanent spot in the boat.

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

Most tandem trippers run one per paddler — one near the bow seat, one near the stern. Each base rides loose on the floor rather than mounted anywhere, so there's no single fixed spot to share, and each one comes off separately at the portage.

Sit-on-top kayaks are molded around a console, so many get a cup recess built into the plastic at the factory. Canoes aren't built that way — no console, no dash, nothing molded in — because the hull is open and every surface inside it already has a job: paddling, seating, or carrying gear. That's a design difference between the two boats, not an oversight in either one.

It's one piece of solid flexible material with no seams, hinges, or moving parts, so there's nothing for grit to work into over a season and no clamp hardware to corrode. Nothing about it wears the way metal jaws or a suction seal does — there's simply less to fail.

Yes — the hull curve that pulls a drink toward the centerline is the same physics in a solo boat as a tandem, just over a shorter waterline. The base doesn't care how many seats the canoe has; it bridges whatever arch is under it.

This is built around the motion of flatwater paddling — strokes, wakes, landings, the ordinary heel of a boat underway. Sustained heavy water is a rougher ask for anything riding loose in a hull, the base included, the same way it would be for a cooler or a dry bag that isn't strapped in.

It's built to bridge the floor's curve, and the gunwale runs only about an inch wide — too narrow for the base to do the bridging it's designed for. Keep it low, in the bilge or between your feet, where the wide base actually has a floor to spread across.

It's sized and colored for exactly that trip — names like Boundary Blue and Dawn Paddle in the canoe lineup — and there's nothing to mount or fit to a specific boat, so it works for whichever hull the gift ends up in. Free shipping applies the same as any order, made in Orange, California.
