No-drill dock cup holders: check the dock before the accessory
Distinguish fixed surfaces, floating movement and mounting permission.

Identify the dock and surface
A fixed dock and a floating dock can behave differently. Even an apparently quiet spot may move when people board or a wake passes. A freestanding base does not restrain that movement.
Check permission and dimensions
Before attaching an accessory, confirm permission and the actual rail or mounting dimensions. No-drill hardware can still mark a surface or obstruct a working route.
Choose a supported table for breaks
Steadi can provide a wider resting base on a suitable dry, level table. Keep its complete 5.2-inch footprint supported and well away from the dock edge.
Change the setup when conditions change
Move the drink if wind, wakes or dock motion make the resting spot unsuitable. Choose an appropriate mounted solution when attachment is required.
