I started my paddling career in 1980 on the dark side, as some here call it. Back then, here in Switzerland, kayaks were used exclusively for whitewater, maneuvered by a double blade paddle. Only a few 'old farts' at the local canoe club paddled in open canoes on lakes. We laughed at them.***
On our first canoe trip in Canada, we learned about the advantages of an open canoe that is propelled by single blade paddles. While preparing for this trip, the idea of using double blade paddles came up. But in 1985 in Sioux Lookout, Ontario, we found nothing like that.
About 15 years ago my longtime tripping buddy had to quit canoeing due to health reasons. I couldn't find another trip mate so I decided to go solo. Again the idea of using a double blade paddle came up. I got hold of various such tools and tried many things to use them effectively. But after about half an hour I always got severe back pain. The fact that I had broken my back as a young man is almost certainly the cause for that. So I began to intensively learn and practice the use of a single blade. To find out what I was doing wrong and to improve my technique, I even filmed myself. If you're interested to watch my attempt on the "bad" (clumsy?, awkward?) side, which is my right hand side, klick on the link below (I hope it works).

Some have mentioned the possible better speed when using a double paddle. That could be the case, I just don't know. If I compare my speed on the lake to that of a sea kayaker or even a rower in a skiff, I am slow. But I often say to myself why should I rush if it is not necessary.
Long story short: I'm a dedicated single stick paddler.
Merry Christmas.
