The new TackingMaster is a wrist-worn tool that’s designed to help provide tacticians with an easy-to-read wind overview that also provides a visual reminder of recent shifts. The TackingMaster ($75, tackingmaster.com) is worn like a wristwatch, but instead of a Bluetooth or Wi-Fi connection, its movements are manually entered based on information that’s generated by the boat’s anemometer and compass. The TackingMaster uses an external locking ring (red), a moving outer bezel (the “compass ring”), a rotating watch face (the “wind dial”) and a mark ring (the two yellow arrows). To use, set the wind dial to the 0-degree wind shift, loosen the lock ring, set the wind direction on the compass ring, set the bearing to the windward mark using the mark ring and then retighten the lock. You can now use this information to determine starting-line bias, shift patterns and upwind tacking angles, without ever having to recharge batteries. Clever!
