Yacht cup holder options: fitted mounts and resting bases
Compare by movement, surface and the way your drink fits.

Installed marine holders
Use equipment intended for the boat and mounting location. Confirm dimensions, attachment requirements and container clearance with the supplier.
Rail-mounted holders
Check the exact rail diameter, clamp arrangement and access around it. Do not infer compatibility from a photograph of a similar vessel.
Freestanding use at a stop
Steadi adds a wider base to compatible drinkware on a suitable table. It has no fastening, suction seal or claimed motion restraint.
Let the drink decide fit
Measure the container base at 2–3.15 inches inclusive and check full seating around handles and boots. If the boat or surface is moving enough to disturb the drink, choose secured storage instead.
