Race: only when there is another boat present
I only race my 340 when another boat is there <grin>It is hard to say where one should start. One of the big keys is to get the most out of your boat upwind. Key is a tight rig, sails trimmed appropriately tight for the wind, waves, and current. More waves, more drive needed, less waves more speed desire.Another factor is to avoid excessive weather helm. If you have to turn your wheel more than 90 degrees to keep the boat on target, you are probably losing speed somewhere. 180 and you have problems. So balance the sail drive between the main and the headsail to avoid that. Full sail in a high wind means excessive healing, and loss of speed. Reefing under such conditions will increase speed.You might start by buying a good book on sail trim. Much to be learned about stretch, wrinkles, leech lines, sail twist, slot between main and the headsail (including making sure that it is appropriately open all the way up, etc. can be found in a good book on sails. My copy of the book "Sails" has disappeared. Otherwise I could give you the author. Hope this helps you get started.
