Why a drink can still tip: bass boat setup checks
Steadi is not a mounted marine holder and does not secure a drink on a moving boat. It does not replace an appropriate underway cup holder.

Check the support before the drink
Choose a broad, level, dry dockside table away from hooks, tackle and boarding paths. Support the entire holder and stow drinks appropriately before getting underway.
Leave room for real use
Keep the fishing deck for movement, tackle and boat operation. During a stop, a separate dry table gives your drink a clear place without adding holes to the boat.
Start again with a new container
A compatible base measures 2–3.15 inches across, inclusive. Check full seating and handle or boot clearance. An open drink remains open: Steadi is not a lid or a guarantee against spills.
