Beverly,

What TK told you in the SA forum was straight up - don't fart around with the tweaks on the boat until you can tack, jibe and round marks with your eyes closed.

I have "base settings" on my boat that I've gotten comfortable with that give me excellent performance in all but the most extreme (light or heavy) conditions. It's set up the same way pretty much every time and I don't waste my time dicking with the boat every time I go out.

Just think about it - that 2% of extra speed you got by tweaking the boat is worth 48 seconds in a typical 40 minute race. That's one blown tack. One bad start. One mis-judged layline. You get the idea.

Until you get fundamental boat handling down, don't mess with the boat.
