I'm 69 and have been SUPing for two years. A year ago I had my right shoulder replaced, now my left one is acting up. It would help if I did' have to switch sides to go in a straight line. Is there a paddle stroke one one side that will keep me going in a straight line?

I think it would be possible LBP. When in Milne Bay outrigger canoes could be paddled on one side. In fact, in some areas the outriggers were covered in and one had to be able to paddle and steer from the one side. Admittedly they had had years of practice - even the young kids! I'm going to try paddling on one side tomorrow and see how far I can travel in a relatively straight line. (I have paddled the outriggers with some difficulty especially if it was windy).

To go straight, here are my 3 tricks:
- picture the "nail" www.gong-galaxy.com/forum/viewtopic.php?p=43629
- keep your shaft in a vertical plane www.gongsup.com/forum/viewtopic.php?p=77774#p77774
- open you blade at the catch (less tiring than a J stroke):

Or just get a board with a rudder.

Also I seem to recall Jamie Mitchell had a fin advertised with a one side bias in it.
