How does the SeaSucker cup holder attach?

It uses a SeaSucker vacuum cup that grips a smooth surface and releases with a lever, so no drilling is needed.

Will it hold a bottle in a foam koozie?

Yes. The cup holder is sized to grip cans or bottles, including ones in foam koozies.

Yes. The cup holder insert can be swapped for a Small Dry Box, sold separately, for waterproof storage of keys, phone or wallet.

It works best on smooth, non-porous surfaces such as boat consoles and sidewalls. Rough or textured surfaces weaken the hold.

No. The Small Dry Box is sold separately; the cup holder comes with the plastic holder and vacuum cup mount.
