Rowing Equipment Patents (U.S.)

Bill Miller

We often think that major improvements in rowing equipment occurred fairly recently, but many, if not most improvements, were patented many, many decades ago with most well over 100 years old. A good example is the sliding rigger that was raced at the World Championships in the early 1980s and then banned at FISA championships. It was patented at the U.S. Patent Department in 1876 (#184,031 - William N. Blakeman Jr.).

We can get a great perspective on how our sport developed by reviewing these patents. Listed here are some of the U.S. Patents issued. I've tried to include inventions that have some relationship to racing and training. I've ignored patents that relate to non-competitive rowing such as most gunwale mounted oarlocks.

Ebay has a great service where you can search for patents. Go to Ebay Patent Search http://www.google.com/patents?hl=en and browse around.
