Adjustable Genoa sheet cars

I read the thread by Alan on the adjustable cars and I am confused. Alan said that in heavey winds he would move them back to reduce healing pressures at the top of the sail. In thinking this through I thought initially you would move them back to flatten the sail. As the wind built I assumed you would move them forward to create twist which would open the leach and spill air from the top. Please put me on the right track! I also looked on the Garhauer Marine site and could not find them - anything specific I should be looking for?

Genoa cars

Moving them back flattens the bottom part of the genoa, but allows the top to twist open. Think of it this way: when you move the car back, the sheet is pulling more on the foot of the sail, but with the car forward, the sheet is pulling more on the leach of the sail. In heavier airs, you might also add jib halyard tension to move the draft forward and decrease power in the sail.

Remember High School Algebra?

I have enough trouble remembering my measuring tape! And I don't understand why the keel and rudder lateral resistance doesn't change.

Too much time on my hands

and the wife is doing her 18 hour/day tour at the Pentagon for the global war on terror so I can't go sailing as much as I'd like. My reference is the Chapman Piloting and the Annapolis guide for sailors. The latteral resistance does change but I was trying to (giggle) keep it simple ;-)
