Found this baby cup holder to be very useful for any kayaker or proangler owner. The clamps open about 3inch max and has a powerful rubberize clamping. Not to mention it's plastic so no rust to worry about. It comes with 2 cup holder and a twist know to tighten the clamp to a bar handle or any part of the kayak that is less than 3inch. For $7 it's cheap and can be your great add on to any kayak that need drink holder.

Here's an example.
