Golly I use waypoints and routes all the time. Waypoints have obvious value in terms of marks, obstructions, shoals, etc. that you need to round or keep clear of. They also give me useful information in terms of ETA, VMG, leeway, currents, etc. Routes aren't something that I hew to like the bird flies, they're just a collection of way points, a convenience, and also observing my track relative to the point to point route can be useful in terms of the information it gives you.

Re: Easy to use GPS Chart Plotters

We have a new Raymarine 10" plotter. Way, WAY better than our previous Raymarine. The Garmin solution was about $1000 more than Raymarine, and the Wifi radar installation certainly helped the decision. Love the vastly improved support from Raymarine too. We had a horrible experience with Garmins support. Ugh. Made us pay for 3 masthead units.

Sure a mark on a hazard is not unreasonable. But your course and heading line should alert you to the fact that your course needs to be corrected. And most hazards will have a safe side or zone and so a way POINT may not be safe to navigate to. You MUST look at your chart. I suppose an arrival zone alarm could keep you away far enough. What's the problem with looking at the chart and see where your heading??????????????? Your course and heading lines will do just that!

TRACKS on the other hand are very useful because they show a path with no hazards that you have already done. I still maintain routes are a waste of time or perhaps time spent before sailing which is usually one has ample time to do as you are sailing. Scrolling the cursor and selecting waypoint at cursor. GO TO is all you need. And it's probably a good idea to do it on the fly because it forces you to look at the chart AND the conditions you are in (WATCH)... kind of engages you REAL TIME. How'se that for an idea? REAL TIME SAILING AND NAVIGATION?
