Why a shore drink can still tip
Check ground, table and container separately.
A table can lean
Stable feet are not enough if the top is sloped. Check the actual drink spot before using it.
Wind and movement still matter
Steadi does not anchor the drink. Move or put away open drinkware when conditions disturb the setup.
Keep the landing route clear
Place the drink away from people carrying kayaks and paddles, not at the easiest place to step over.
