I put in an inquiry for oarlock bushings today and the following link came to my knowledge. I have never heard of the company before, however they have a wide variety of products those of us who have boats, canoes, kayaks, pontoons, etc., need from time to time and for aspiring boat builders they seem to have a wide choice in design plans. On top of that their prices look really good compared to the big name marine supply houses. No recommendations, just a heads up.
