    I’m definitely getting old. The first version of the entry had the big MFD as a gS125 when it’s actually a gS165. I knew it looked good but underestimated its size, which may be a modern phenomenon?
    I also heard from the Raymarine demo (and video shooting) boat team that the Evolution did “auto linearize” itself after I left, which fixed the radar overlay and COG/Heading discrepancy on all courses. Apparently the developers in the UK are working on an explanation of how that process can vary boat to boat and we’ll get a link soon.

    Ben,
    After consulting with our autopilot development team, we’ve learned a few things about the logic inside the Evolution EV sensor core that explains our post factory reset heading anomaly that should be of interest to your readers. Out of the box or after a full reset the EV sensor core automatically linearizes itself, normally achieving a baseline calibration in 1 to 2 minutes. The EV sensor then continues to monitor and improve from there. The exception is when the EV sensor senses less than ideal conditions for linearization. When this happens the EV sensor actually pauses the linearization process and waits for conditions to improve.
    It turns out there are some different conditions that can cause the EV sensor to pause its initial linearization process
    1. Boat speed less than 3 knots.
    2. Boat speed greater than 15 knots.
    3. Rate of turn too low.
    4. Sensing a large magnetic anomaly
    During our Sea Trial on Monday we removed the existing baseline calibration by doing a factory reset. Next, we got underway and had conditions 1, 2 or 3 in play almost the entire time. As you noted Evolution did a great job of holding course and passed the single engine test quite well. However we did see the discrepancy in the heading vs cog because Evolution had paused its automatic linearization process. Here is why:
    We left the dock at no-wake speed (too slow), on a mostly straight course across the lake (no significant rate-of-turn), and then ran fast (too fast) to demonstrate Evolution’s high-speed tracking and get over to where the Lady of the Lake Wreck was located. At the wreck site we made lots of circles (going too slow again.) Then we headed back to the dock going too fast and too straight again!
    After you left we took the boat out again for a video shoot and Evolution’s automatic linearization process completed and the heading anomaly was gone. So lessons learned…proceed at a moderate pace, exercise the steering wheel more, and never let the marketing guys reset the autopilot!!
    Thanks

    Thanks, Jim. That also makes sense with my EV-1 experience on Gizmo. Right off the bat I was making medium turns at medium speeds getting out of the harbor and yacht gawking, and once we settled into route cruising EV Heading seemed good to within a few degrees wherever we turned.
    So maybe another lesson is that while Evolution does not require a tedious and often difficult 2.5 circle calibration on flat water at a steady RoT, it may be a good idea to do a couple of mid speed donuts with a new install. Also, if we could do a replay I might have spoken up something like, “Um, Jim, maybe should see how the techs set it up before you mess around.”

  4. Interesting – I just installed an Evolution on our Tayana 48, and took a trip up to the yard and back (over a couple weeks) as the “sea trial”. Total distance is about 20 miles RT, with several turns along the way (Emeryville up to KKMI in Pt. Richmond, SF Bay) Right out of Emeryville I did a couple circles both ways at about 5-6 knots, but discovered the compass/radar synch was off about 10 degrees after I straightened out. I did a compass calibration twice, and that helped, but the heading vs chart calibration was off by significant (and different) amounts at different headings all the way there and back. I’ll be out again on Friday this week, and I’ll run through it all again, but I was not impressed with the initial outing. Other than that, however, the pilot did VERY well – noticeably better than my old j300X/AP22 that the Evolution replaced.
    Now I’m crossways with Navionics because the initial update on my “All US” Gold chart chip is so huge it is impossible to get it downloaded before their server times out (and the 100 mB setup files came easily in a few minutes).
    I’m sure it will get sorted out sooner or later..:-)

    On the photos it seems A series MFDs now have black bezel instead of silver bezel ? Great ! Will it be available as option ? Thanks. (Still using his old C70 😉

  6. Ben Ellison Ben Ellison says:

    Laurent, I guess it’s possible that black bezels will become an available option, but the ones on the demo boat are apparently the result of Krylon spray paint and the aesthetic initiative of the installers 😉
    I like the look myself and think that helm would be even sharper if Whaler or Raymarine had used a black panel inside that nice dark-gray trim piece.

  7. Easymatic says:

    Has anybody tried mounting the evolution system in a steel boot.
    Is it possible to the sensor bellow deck without affecting accuracy?

  8. Ben Ellison Ben Ellison says:

    Hi Easymatic, I’m pretty sure that the EVO nine-axis sensor package actually contains three three-axis sensors, one of which is magnetic. The install instructions seem to bear this out:
    “Location must be at least 1 m (3 ft.) away from any source of magnetic interference, such as compasses and electrical cables.”
    Apparently the gyro and acceleration sensors along with a lot of computational power can automatically compensate for a certain amount of magnetic interference. The Evo package can apparently also handle a fair amount of boat motion so it’s OK to mount one on deck or higher, which is probably the recommended install on a steel vessel.

  9. Easymatic says:

    Hi Ben, thanks for your help. So I understand the deviation coming from the steel vessel itself is compensated digitally however stronger influences like electric wires and magnets should be kept at 1m distance. I hope people with steel vessels with first hand experience can confirm! Cheers, Frank

  10. OK, Ben here’s what I have..:-)
    I installed the Evolution system on our Tayana 48 in July,and did a couple of shakedown cruises up & down SF Bay (had to go up to the KKMI yard in Pt. Richmond, plus a couple days out sailing around).
    Note that my previous AP22/J300X autopilot was using a Raymarine hydraulic drive, and we retained this drive with the new Evolution. I did have to change out the rudder sensor, and I put the Evolution sensor in the same spot as the olde fluxgate compass had been, which was below the sole in the aft stateroom – about 8′ aft of the engine, and maybe 8″ above the hull, midway between the dripless bearing and the SS strut underneath.
    Subjectively, the Evolution worked better than the older unit – 1 and 2 degree corrections were meaningful, and stability/course keeping on a straight course was noticeably better. Navigating in & out the channel from Emeryville was very easy, for example. The only fault I found was noticed because of the other new electronics I had installed – an e95 and HD radar. Registration of the radar to the chart was good on all headings except Northerly – within 20 degrees or so of North (I didn’t resolve this like I should have) it showed significant error (10 degrees or perhaps a bit more). I attribute this to some sort of magnetic anomaly on my boat that exceeded the sensor’s ability to compensate out. I did a number of circles, etc. iaw the manual, but the anomaly remains.
    I am going to investigate moving the sensor to a different location, further from the engine, shaft and prop.

    Have had the Raymarine Evolution autopilot instaled on my 11m steel hull boat from 1976 and it works great. Very impressive! The puck sensor is positioned in the cabin right beneath the steering wheel next to the fuses and under a whole bunch of wires. This does not seem to affect precision in any way.

  12. OK, I moved the Evolution sensor, and all the “Northerly” glitches have dissipated. As I said earlier, the initial location was under the sole in the aft S/R, where the fluxgate had been, about 6′ aft of the engine. I moved it basically vertically about 7 feet – it’s now in the overhead perhaps 6″ forward of where it was earlier, about 24″ aft and below the helmsman’s butt at the wheel. While there were a few 1-2 degree misalignments, once I had it calibrated (I scrammed it and started over) it was basically dead on on all headings – including North!

    Raymarine’s R4 EVO autopilot update looks great:

    Among other improvements the 9-axis sensor can now stabilize wind data. I hope that Hartley and others try it and report back 😉
