Ok first of all what most sailors dont seem to understand is the back winding the jib also slows your tack down. When you go into a tack you let the jib off a little to say about 12 inchs off normall which should be just before the jib hits the mast. This helps the boat go into the tack quicker. If you dont do this the jib back winds to early and just wants to make you reverse the boat out of the tack when your main wants to go forwards through the tack. Fun work hey.

Make sure your main is all the way on untill the wind hits the other side because the main makes you bear into the wind there fore helping the tack. Also the smooth tiller is always the best thing to get her through.

well have fun and just get practice!!
