I have been using different approaches to mount my camera or camcorder on a boat deck from various mini tripods and clam pods to mounts improvised with a foam, bungee, and duck tape. Recently, I almost entirely use a suction cup mount from Sticky Pod Camera Mounts. I have found it reliable and easy to use.
The sticky pod has been involved in shooting of all my movie clips and paddling self portraits in interval camera mode since 2005/6 winter.
The sticky pod mounts come in different configurations from a single cup mount to heavy duty mounts with 3 or 4 suction cups. The essential part of this system is a strong suction cup with a 1/4" thread. It can be connected to any standard photography tripod head or anything else using 1/4" bolt.
My original plan was to paddle nearly 40 miles of South Platte from Orchard to Cooper Bridge. I wanted to resume my February low water paddling Masters to Orchard and explore another segment of the river. In winter, I also paddled the last few miles of my course: from Cooper bridge upstream to Snyder and back. Connie agreed to provide a shuttle. She was accompanied by my mother visiting us from Poland.
First troubles appeared at the Orchard bridge when preparing my safari boat (Spencer X-treme canoe) for launching. A local farmer asked me not to disturb duck and goose nesting area by paddling the river below Orchard. It seemed that he put two fences across the river to protect the area. After some discussion I agreed to move my launching 4 miles downstream to the next bridge at Goodrich. He wasn't aware if I would encounter similar problems further downstream.
