I'm having fun making a set of 8-foot oars for my Northeaster Dory. I've used some lumber from Home Depot and the basic Pete Culler design and can now see that I will at least get a pair of oars out of it. They could even be good oars, but time will tell about that.
Anyway, once I finish the boat, I'm looking forward to trying out these oars and I've never owned (or used) any oars except ones with pins through them. So I'm wondering what is the function of the leathers? To cushion and protect the wood? To make things quieter? Something else? And that brings up a second question, can I use some vinyl-covered canvas that I have left over from building my skin-on-frame kayaks to serve as leathers? I know that the purists among you might be outraged at this rejection of tradition, but still . . . would it work?
