communication is the key.On a three day trip one year 15 minutes in on an easy stretch of river my partner and i were rafted up to another couple,we decided to split up and as they drifted along sideways taking in the scenery they both noticed a rock downstream (this husband and wife team paddle class 2 rivers together)she in the bow thought no problem three quick forward strokes and they miss it,he in the stern thinks 3 quick back strokes and they miss it well one wrapped boat later they were both walking opposite directions on shore.So no matter who is were communicate
I always carry a spare. Did bowron lakes this summer,2 boats 5 people,= 4lake paddles there was some moving water so 2 whitewater paddles and lastly 2 kayak paddles, these work great in an open boat for a change in muscles or on windy days
