Al just wanted to let you know I finally recovered enough from hand surgery to use the YAK-A-LAUNCHER™.
It was easy to assemble in about 15 minutes. Treated the rollers with the solution you recommended. It was easy to put overboard and retrieve to my floating dock. Easy to enter and exit. It made a stable surface to enter and exit the kayak. My only regret was that I didn’t buy one ten years ago when I first saw them.
