Autorouting: Navionics new Dock-to-Dock kicks it up a big notch

    Keep em coming

    Happy New Year Ben and all readers of this great blog.

    I store my boat at Kingman over the winter and consequently have been in and out of Cataumet many times (in fact I just heard from my boat over there – the Siren Marine monitoring system sent me a text with a “low temperature alert” because the yard unplugged my shore power for the holiday break when no one would be around and it cold cold last night).
    The autoroute took roughly the same track that I laboriously plotted several years back. The aids to navigation shown on the inset as you get close to Kingman are privately maintained and do move around a little.
    Another quibble is that there is no indication that the last 1/4 mile in Red Brook Harbor takes you through a very dense mooring field that must have 200 boats in the summer.
    I do worry about this technology in the hands of inexperienced operators. Probably a double edged sword, however, as it will help many of them find safer routes than they might choose on their own.
    Happy New Year and keep up the great work.

    Your little “quibble” reinforces the adage, “To keep a proper lookout”.

    I am slightly amazed that with all of the class action lawyers lurking to pounce that the manufacturers are even willing to sell auto routing in the US. One can only imagine the litigation if someone had engaged autorouting and ran themselves into danger and suffered injuries or death. Sure, we all know that under maritime law it would likely be 100% their own responsibility but that never stops the lawyers.

    Pretty cool. Do you know if it deals with traffic separation schemes? I would be really impressed if it came up with the proper ninety degree crossing of a traffic lane.
    I would be super duper impressed if it handled the notorious area WG in B.C. which is a live torpedo testing range that gets hundreds of boaters in trouble each year. It lies across the best route for boats headed to Desolation Sound or Alaska. If you cross it when it is active you will have helicopters and armed patrol boats chasing you. If raymarine came up with a WG warning the Canadians would be most grateful. To make things interesting there are several marked regions in the area so it is not so easy ro discern on a chartplotter…

    Autorouting can be a useful tool if properly employed. I teach the USPS/CPS Electronic Navigation Systems Class and I recommend to students that they carefully go over the routes that they create before actually using them for navigation. The same should apply to automatically created routes.

  8. Scott Zeien says:

    Kingman regrets that your shore power went out over the holiday week. We experienced a power outage on the street and the neighborhood was down. Apparently your boat’s systems did not restart when power was restored.

  9. Quitsa says:

    Thanks for the personal service! The power is not yet back at least to my boat. Maybe the breaker tripped on the panel.

  10. Paul Lever says:

    If you auto-route between Point A and Point B vs between Point B and Point A do you get the same course? There should be some bias in the routes so that you do not encourage Chartplotter assisted collisions.

  11. Waterford says:

    I just entered a route between Nanaimo and Half-moon Bay and it does not route around WG.

  12. Ian Threlfall says:

    Raymarine has just released Lighthouse V16 – unfortunately Dock to Dock is not included … patience is a virtue!

  13. Ben Ellison Ben Ellison says:

    Thanks for the news, Ian…
    …though lack of Dock-to-Dock is a disappointment, hopefully just short term.
    Then again, it may nicely illustrate why C-Map’s new close relationship with Navico may eventually mean faster, more reliable cartography feature integration:

    And that is the reason why Garmin uses its own mapping and not someone else’s. Garmin has had auto guidance for ten years now and finally another brand made a copy. Also the way Garmin makes its waypoints and routes is getting copyed now by Raymarine.
    Is my love for Garmin so wrong?

  15. I spent the last two weekends using auto routing both on Navionics on the iPad, and via Navionics charts on my Raymarine eS78. I agree with Ben that while it made some good routes, I ended up saying “I’d rather not” in a number of cases where it cut really close to shore, or other things that I just don’t do for safety’s sake.
    Wrote up a little bit about it in a recent blog post at

  16. My system won’t autoroute. I’ve got a brand new Raymairine Axiom Plus and inserted a Navionics Platinum :lus mSD. Everything works except the autoroute. It just draws a straight line from point to point without any regard to hazards etc. I updated the navionics card before inserting it.
    Any thoughts??
