I recently tried out Rick Rosenberg's Standnfish: a leaning post and pontoon system that's really neat. The pontoons raise out of the water for paddling and can be lowered easily.

You can stand on your seat -- or on the gunwales to get a little higher.

When the pontoons are down, the kayak is very stable. Adds a new dimension to sight-fishing. The system is available and reasonable. Check it out at www.standnfish.com.
