I never go by lbs, psi, whatever. What matters is sail shape and forestay sag (or lack thereof). I have a small dinghy batten taped to the AFT side of the cylinder of the backstay adjuster. On the batten are small wraps of green, yellow, red and black tape. These are positioned so the fitting on the backstay will line up with them when the rig is tensioned. On an upwind leg of a race, we tension the forestay to shape the sail how we like it, then look at the batten and take note of which tape mark the fitting lines up with. On the next upwind leg, if the wind and waves are the same, we tension the rig to the same piece of tape.
Green = light breeze. Yellow = moderate breeze. Red = heavy breeze. Black = OMG, we're going to die! The tape wraps on the batten are MUCH easier to see than the gauge. If you look closely, you can see the batten on the aft side of the cylinder here: https://drive.google.com/open?id=1zzjRreszZF9YCbb5zBfTLGBuVtim4mcZ That's not a good picture. It was taken to show the jury rig to tension the backstay after the adjuster lost the top seal. :( Dennis C.
