Ignore the wind instruments and sail the wind... Buy a handheld anemometer and shoot the wind on the prestart. Write the HTW angle down then monitor
shifts during the race
Some pictures of the sails in this condition would be useful.
Trim the genoa
cars so that the tells break evenly top to bottom or stall slightly at the top first. As I said closing the leech of the genoa even further (cars forward) should produce more force forward of the mast.
up more. I am becoming sure that you are not really on a close hauled heading. Think about it. If everyone else is close hauled and you are 10 degrees off them, by definition you are not close hauled.
If you are not winching the vang/mainsheet in 15+ knots you are not trimming the main hard enough. We also winch
. The mainsheet and vang should "twang" like a piano wire... (OK at least a low "E" note - LOL...)
You are able to get 6 knots boat speed in 15 knots wind. A very simple exercise is to head
up (somewhat smartly) until the genoa tells luff and the boat stands up - then "smartly' again - head down 1/2 the distance you headed up.
boat speed & heel. If excessive heel head up again and then back down 1/2 the angle. Eventually you will be steering
a very narrow zigzag, controlling heel and boat speed with helm
. As the driver, you are locating the point at which the sails stall. If you cannot locate that point you cannot successfully race
It will feel like an unnatural act because I suspect as you head up the first time the boat will heel even more and it will feel like you are doing the wrong thing.
7 year old sails are bad but not terrible. My main is now 10+ years old and until replaced 4 years ago my genny was 6. We were placing well and getting podiums.
