Love sailing? If you answered in the affirmative, then surely you would be familiar with the activity known as tacking, where you can then derive your Estimated Time of Arrival (ETA) as accurately as possible. Unfortunately, sailboats happen to tack back and forth while they are out on the open sea, which is why the right tacking distance is often difficult to calculate, not to mention it skews the end result of your ETA as well. Good thing we have tools like the Sailing GPS which you can read about further after the jump.
The Sailing GPS will solve the issue faced by standard GPS chartplotters, where it takes into account the exact length of each tack, in addition to the amount of time required to sail each tack, and the optimal tacks so that you can be the first to arrive, if you are sailing in a group, that is. Google Maps will also see action here – not to know just how frequent the London Underground service is, but to help you mark waypoints in a snap. All you need to do is hook up the Sailing GPS via Bluetooth and you are good to go.
