We start this book by looking at the most important aspect of good and safe navigation. More important than fancy electronics. More important than paper charts. More important than radar. Situation awareness—knowing where you are at all times.
Although we are not Luddites bemoaning the take over of electronics and warning of the dire consequence of over reliance on them, we are aware of several dangers in their exclusive use:
Here’s one simple tip that can save you a huge amount of grief…and possibly your boat:
