| TACTICIAN'S CALCULATOR |
| Mfg. by Weems & Plath. The Tactician’s Calculator is a hand-held tool for the racing sailor. This easy-to-use tool provides you with a visual depiction of what is happening on the racecourse. The Tactician’s Calculator can help you determine: how square a starting line or racecourse is, what your heading will be on the opposite tack or gybe, how close you are to layline, and what point of sail you will be on for the next leg of the race. On the reverse side of the tool, there is a key to the most commonly used racing code flags that gives you a picture of the flag and an explanation of its meaning. There is also a speed/time/distance table, and an area to record both wind and racecourse information. The Tactician’s Calculator comes with a #2 pencil and has holes punched in all four corners for easy tethering. Dims: 6"x 8 1/4". |
