This video was shot from the beach showing the sprit rig in light wind and the small sail in 25 knots of wind.
The best sailing videos are shot from a chase boat but unfortunately I didn't have one. Shooting from onboard with any conventional lens gives a narrow field of view and misses the best times because your hands are full when things really get going.
For these reasons I have just ordered a Go-Pro Hi definition waterproof head cam that can be mounted on the canoe. A 170 degree field of view should make a remarkable improvement. Stay tuned.
