Industrial strength safety
Rope clutches, or stoppers, are wonderful items to have on board. Not only are they quick and easy to operate, they eliminate the need for extra winches. But each one must be labeled so the trimmer can see immediately what line that particular stopper controls.
When San Francisco sailors Russ Irwin and Fay Mark labeled the clutches on their brand new 52-footer New Morning, they wanted to be absolutely sure there could never be a situation where someone might be confused about which lever was controlling which line. Their solution; put the same label on both the top and the underside of each lever. Smart idea.
