We had this discussion many years ago on this list. I think I recall that this is tension (in pounds) on the wire/rod. I think the reading on a hydraulic back stay adjuster gauge is pressure (in psi) on the piston. If so, they are not the same.
I think you have to convert the psi reading to tension based on the area of the piston in YOUR adjuster. For instance, if your piston is 1 1/4 inches in diameter, you would have an area of 1.23 sq inches. So 1000 psi on the piston would exert 1230 pounds tension on the back stay. I could be entirely wrong. Can someone verify this? Touche's hydraulic back stay gauge is too opaque to read. We adjust to sail shape and have a batten with green/yellow/ red/black tape marks for repeating settings. -- Dennis C.
