Navionics Automatic Routing

[Hadenough]

Not extreme in the slightest.

Climb onboard, set the boat to follow the auto route and relax with a small glass of something with your guests, next thing you are driving up the beach at 25 knots. Of course none of us would ever do that

Absolute crap. Move with the times. Use autoroute, double check its prediction, alter if necessary (usually). Follow the route suggested on the plotter, take into account the physical waypoints as you progress and hourly, put a plot on a paper chart to verify everything. I can understand those who like to sit and work it all out manually and agree that you should be capable of doing it if everything goes tits up but why make things difficult if you don’t need to? Recently there was a post on here from a very experienced bod moaning about autoroute. Turned out that he was not verifying it with anything else. When I passage plan I use Garmin autoroute, check it against Navionics and the run it over a paper chart, if anything doesn’t agree it gets quadruple checked. Or you could always just rely on a chart and a wet finger in the air ?.

What is the width of the land at that point? I suspect that it is less than the data points that the automation software uses. One really good reason not no rely on electronic charts at sea.

Autorouting is not the same as electronic charts. That piece og land is clearly visible bye human eye.

As they say in the old Internet days, "our experience is different", I've seen too many boat on autoroute and people not paying attention.

Being an old fuddy, duddy who spends time with paper charts I have a mental picture of the passage in my head.

How do you know that they are on auto route and not just on auto pilot? I have a good picture of the passage ahead that comes from passage planning and using the zoom feature on my chartplotter and or Ipad. I also have paper charts on board because I like them, but I have to say I rarely use them.
