In my opinion, the oar locks which are shaped like a "U" and have a 2 1/2" x #10 or #12 machine screw that goes through the oar, as opposed to the circle oar locks, make it a lot easier to row. They just do a better, all-around job of positioning the oars without any slipping about......and you need to drill the smallest hole that's doable.....through the wood oar.

For the lowest price, best deal on these, about $10.95 for two, suggest you go to Parafunalia in Gilford. Aubuchon charges something like $24 for the same exact item.
