GPS is very good for plotting distance when fairly direct travel is involved, but this isn’t always possible. One notable area where this can be difficult is with sailing as tacking to catch the wind is necessary, making it nearly impossible to determine arrival time.

But the Sailing GPS is a purpose-built device that can in essence not only solve the problem but even help determine the best course to follow, including where and when to make the tack. It can also work with Google Maps to mark waypoints, and it supports the latest wireless, solar-powered SailTimer Wind Vane. It even comes with a dryPack bag with tiedowns so it doesn’t float away or sink!
