Why drinks tip around a canoe—and what a wider base changes
Separate tipping, sliding, splashing and falling overboard before deciding what accessory you need.

Tipping and sliding are different
A drink tips when it rotates far enough to lose upright support. It can also slide while staying upright. A wider base changes the support footprint, but that alone is not proof of a particular tilt limit, grip level or resistance to sliding.
A moving hull adds changing conditions
A canoe can change angle as people move or water acts on it. Curves, water and loose gear also change the available support. We have not established a Steadi rating for those conditions. Do not assume it levels a drink, bridges a curved floor or locks onto a wet hull.
An open drink can splash without tipping
A cup can stay upright and still lose liquid. Steadi does not close the container. If containing the liquid matters, evaluate the actual lid or closure and use it according to its maker’s instructions.
A mount solves a different problem
A suitable installed holder provides an attachment to the boat; a freestanding holder does not. That distinction matters when retention is the goal. No claim is made that Steadi floats, prevents overboard loss or secures equipment in a capsize.
Use the wider base where the conditions fit
On a level, stationary shore surface with the full 5.2-inch footprint supported, Steadi gives a compatible drink a broader base. Keep the drink in reach, leave room around it and move it before moving the surface underneath.
