Just pointing you to some results.

Believe me, it took FON, Ding, Alex, Capt Kirk, and some other notables about two years to beat the pinching out of me on a sloop. I'd bet I'll still pinch to the stars on a uni

Its also a really bad habit from dinghy sailing for some, as the breeze builds in a slow boat (V15 for example), one can pinch to make better VMG. Of course, good boats plane upwind and there is a point where pinching really kills you because you can't plane while pinching (unless its blowing beyond stink).
Time on the boat is what separates good drivers from the best. A custom UNI sail may help but if you are pinching thats not going to make much difference. Footing off slightly in any high performance boat is usually better than pinching slightly.

Posts: 5,590 Naples, FL | therin lies the rub... how to get a handle on pinching/footing in "uni" mode.
From your comment, you can't judge the telltales the same way as you would in sloop mode.
Which begs the question as to what method works best at evaluating your heading.
Would it be safe to assume the best means would be heading down until the backside stalls and head up 5 or so degrees?

The tells on a main are not nearly sensitive enough to steer off , in my opinion. 5 degrees in angle is way too much swing normally and the amount needed is dependent on the wind and wave conditions so some fixed number is bogus 99% of the time. I have asked a lot of the top guys what they use and pretty much universally the answer has been – FEEL Know your boat. If you are not moving forward as fast as you should (or as fast as those around you) with the wind pressures you are in then you are doing something wrong with the tiller and/or the sheet. | | | Re: vmg for uni

Pete, one way to quickly develop a little more feel is to let some kid who doesn't know how to drive, drive your boat.
I find when I let my kids drive, I can tell if they are too high or too low just by the sound the water is making coming off the rudders. You will be able to feel the boat slowing down when they start pinching, and of couse the sound gets quieter as they slow.
If you can't find a kid to steer (poorly) for you, then the next time you go out alone, try sailing upwind with your eyes closed and listen to the sound the water makes as you slow or accelerate.
The kids just got home from school, I've got two boats rigged up out back and we are going out to practice our -feel-. It is kind of light wind out which only makes it more important not to pinch! Stall a Hobie 14 in light air and you are going to be sitting there a while!

Posts: 548 MERRITTISLAND, FL | AAAAARRRRRGGGHHHHHHH!!! [beating head against wall] Some of us just don't have that feel. The guys with natural instincts still have a gazillion hours sailing and sailing fast. This is why we race – you get to line up repeatedly with other boats. If you cannot “feel” it then you should at least see how you are comparing to similar boats. If you are not going as well then you have a 99% chance it is the tiller and/or the sheet. Next to the A, the F16 is by far the most sensitive boat I have sailed. It provides pretty obvious feedback when it accelerates or decelerates. Trim and helm adjustments are likewise almost instantaneous. If you make the boat go faster, it is almost always the right move. Other than that I use noise a lot. A loud noise from the wake and you know you are not balanced. There is a definite rhythm to the boat going through the waves and the sound of the wind. Slow beat means slow boat. When I have helm issues or the helm feels heavy, I know I am not sheeted properly; I’m pinching or doing something else to make myself slow. No magic pills. Just time and being aware. | | | Re: vmg for uni

Crap, Tim. He already did that when he invited me out for a sail a little while back....

Smell that fresh breeze Pete?
