Isn't that the message we hear again and again. Get your trim into the ballpark and then concentrate on driving the boat. I suppose the problem when beginning in a new boat is to know when you are in the ballpark?
I found the A to be way overpowered to weather. It is so light and narrow with the very high aspect rig. I am light and no amount of adjustment made any difference what-so-ever as soon as it got to 12Knots. Just ask someone who has already been sailing and is near your own weight where they are at settings wise. Spreader rake and tension, and then mast rake (mast rake dependant on the boat type) Bingo - Your fully tuned. <img src="http://www.catsailor.com/forums/images/graemlins/smile.gif" alt="" />
In reality the ball park could be defined as the mast pointing up - The rudders and boards pointing down and the bow forward gets you in the ball park. <img src="http://www.catsailor.com/forums/images/graemlins/blush.gif" alt="" />
