Yeah: Rotary motion is more efficient than reciprocating motion. The trade 
off is on loss of mechanical efficiency in a gear/drive shaft system 
(although this may be negligible). The best may be a simple propeller as on a 
sailboat, the kind that folds up when not spinning.

Peddle powered kayaks are an interesting concept that appears to be only 
useful on a sit-on. I certainly would not have room for pedals in my touring 
boat, unless I chopped a clearance hole for my knees in the deck.
