A calm berth offers different resting options from a sailing cockpit. Separate an open-drink break from the holder needed underway.
Use a dry level table during a suitable calm stop with the full 5.2-inch base supported and access routes clear.
Use the guides below to compare the resting surface, the fit of your exact drink, and the type of holder that matches the problem.
The interruption you know too well.
Reaching to turn chart catches drink; water wets chart corner and seat towel.
Trace the movement before choosing the holder
One scenario to check: Reaching to turn chart catches drink; water wets chart corner and seat towel. Notice what your hand was reaching for and what was beneath the container. A drink can be within reach yet still sit directly in the path of that repeated movement.
Arrange the drink spot while moored, outside the chart and line-handling area. Stow open drinks before getting underway; the holder does not anchor them. Test the setup with an empty container first. The entire base needs level support.
A sealed container addresses liquid escaping when tipped. A stable surface addresses support. Steadi widens the resting base of compatible drinkware; it does not replace either of those decisions. Check your exact drink fit, then use the guides below for the setup you have.
