From a series of racing tips from J World Sailing School: When is a windshift shift worth tacking on? When is it better to tack on a shift versus going for stronger wind? To answer questions like these it's helpful to know how much you'll gain in a shift. If you can quantify your decisions, they are often easier to make. Here are some rules of thumb regarding distance gained/lost in a wind shift: - If your boat's tacking (or gybing) angle is 90 degrees then you'll gain 12% of the distance between boats in a 5 degree shift, 25% in a 10 degree shift, 37% in a 15 degree shift and 48% in a 20 degree shift.
Example: If you get a 15 degree shift and you're 1/4 mile (1320 feet) away from a competitor then you'll gain or lose 488'. If you're sailing in a J/80 this equates to about 19 boat lengths. That's a lot!
- If the tacking/gybing angle is larger, then the percentage gain/loss is also LARGER. Keep this in mind in light air when angles are greater.
A big component of the final figure is the separation between boats. This separation is often called "leverage" Leverage can be good or bad depending on which way the shift goes. Tacticians should always run the "what if" numbers ahead of time. This is especially helpful when considering hitting one side of a leg due to an expected geographic shift caused by land.

During our March 8 race, a film crew from Delta Cable was taken aboard LUANA and given a power-boat-eye view of the race by skipper Mike Bayliss, who provides some enlightening commentary about racing to viewers. For those who remember the race, it started out in the rain. It was held "around the corner" up to the international mark. As we arrived and got underway, the skies cleared and we were treated to a really nice rainbow, which you will see on the video. Toucan was the committee boat. Here is the surprising result of their filming. Pass the popcorn and enjoy! By the way - I am reasonably tech-savvy but I'm no video expert. DCC left 5 seconds of the previous story with some really cute kids singing at the beginning of the file, which I haven't figured out how to edit out, short of shelling out $40 for software like "quicktime pro". (Windows Movie Maker doesn't seem to work well with the mpeg4.) If anyone can help me with this I can send you the file. Then I will re-upload it to youtube. Courtesy Delta Cable |
