Some advice regarding doing races on F16 when 1-up in shifty and light winds
Put telltales on the LEECH of your sail. Mid upper panel, just below mid leech overall and one halveway between those two. When sailing uni-rigged you have to sail by these. The telltales in the sail are not much help in really getting going because the stream to easily. I found that I'm inclined to oversheet my mainsail often.
second tip. Go to www.tacticat.com
register (for free) login and do alot of races practising your tactics regarding shifts, wind strength, racing rules and general covering of the your opponents. You'll learn heaps and because after a while you know them by heart when on the water you'll make alot better use of these on the water in an actual race. I really advice this online training. Apparent quite a few of us F16 sailors are doing it as I've encountered a fair share of those in the game already. (you often race against real people and can communicate with them)
