Kayak cup holders: mounted or freestanding?
Choose the holder for the phase of the outing.

Track-mounted holders
A compatible mounted holder can attach to an intended kayak track. Check the maker’s exact track, fastener and container requirements.
Secure storage
A closed bottle in suitable storage solves a different problem from setting down an open drink. Follow the kayak maker’s arrangement for loose equipment.
A base for shore breaks
Steadi is useful at a suitable resting surface ashore. It needs container bases 2–3.15 inches across and 5.2 inches of full support.
