Response to Frank re vang
The mainsheet tackle on the H23 is much more powerful than the vang. When sailing close hauled, the downward pull from the mainsheet is so strong that the vang goes slack. At that point the leech is also tight.Easing the sheet in the puffs opens the leech and changes angle of attack simultaneously. The boat goes from overpowered to upright in a heartbeat. It takes a lot of finesse on the mainsheet to keep the boat in the groove and that's hard to do with a lot of load in the mainsheet tackle.For me, the easiest solution was improving the traveler. Here's the added advantage. On really windy days, I haul the traveler far up to windward and then ease the mainsheet to put the boom back near the centerline where it belongs. This takes a lot of the load out of the mainsheet tackle but maintains the proper angle of attack. In a gust, the boom rises slightly, the leech opens, the top of the mainsail twists off and spills excess air off the top of the sail while the lower half is still working the way it should. It looks odd, but I can sail upwind with a full main when everyone else has reefed. I've raced the boat singlehanded using this technique and it works.PeterH23 "Raven"
