Paddleboard drink mount or shore-side base?
Match the accessory to its attachment requirements.
Board attachments
A mounted accessory needs a suitable board connection and the maker’s instructions. No universal attachment is implied.
Closed storage
A closed bottle in appropriate storage addresses a different need from resting an open drink at a table.
Steadi ashore
At a suitable surface, Steadi widens a compatible container’s base. It has no flotation or on-water retention claim.
