Harvestman, think of the pegs like the pedals on a bike you can roll down a track without them but you have much more control and can apply more power with them. Another way to look at it is that you sit in a canoe, but you wear a kayak, with your feet on the pegs and your knees braced under the deck you should be able to move the boat using only your hips. The boat should be fitted to you so that you remain in contact with it no matter what angle it is at. Another comparison would be trying to drive round a racetrack at speed in a car with a vinyl bench seat compared to another with bucket seats and full harnesses, its all about control. As for the footpegs if you drill the hull you simply seal around the bolts with sikaflex , most kayaks have their footpegs bolted in place.
