DIY Canoe rowing rig 

I also have an Intex inflatable kayak (smaller version though). I would not try attaching any kind of oarlocks to it as I think it is simply too flexible. The attachment points need to be fairly rigid, which would be hard to do with an inflatable. Also, I find the hull shape on my Intex to be quite limiting to speed.

@@jacobinalberta I wanted better efficiency. Seems I need to improve my technique!

Laterally, it depends on the length of your oars. The pivot point should be about 7/25 down the length of the oar, so for an 8ft oar like mine I put it about 2.25 ft from the inner end (approx centre of the boat). Put it a couple inches closer in for overlapping oars, or a couple inches further out for non overlapping oars. Longitudinally, I sat in the boat and found the spot where the oars go straight out at 90 degrees with my arms straight in a neutral seating position (not leaning forward or back). Hope that answers your question.

@@jacobinalberta Thank you!

www.frontrower.com Check it out. I have used one for years in our canoe, it is nice being able to see where you are going and to use leg power to row.

pushing the oars gets extremly tiering after a bit. good thing with canoes is that they dont have a back and front

Yes, I suppose. The supports for the oarlocks would probably have to be much longer since kayaks tend to be pretty narrow. You will also be going through the water stern first, so some hull shapes may not be suitable.
