It's a little late for this, and sorry if somebody already said it, but if you want to do 200 tacks and 200 gybes, it will take 200 figure of eights, not 50. If you do them on beam to beam, it will take 100 to do 200 tacks, and another 100 to do 200 gybes. If you do them upwind/ downwind, you will do 1 tack and 1 gybe per eight, it will take 200 again....
