Raymarine Axiom and Lighthouse 3 first impressions

Grace is mostly a Raymarine boat in terms of the key components responsible for navigation. The chart plotter, auto pilot, and helm instrument displays are all Raymarine, paired with sensors and devices providing data from many other vendors such as Maretron, Vesper, and B&G. Choosing Raymarine was deliberate back in 2015 when I bought Grace as I was looking for a very integrated suite of components that could automate the most frequent tasks on the boat while underway.

Make sure to check out my update on Lighthouse 3.1 and new autopilot integration features, released July 2017.

Raymarine impressed me with the quality of hardware and software at the time, and the frequency they have come out with updates and enhancements to Lighthouse 2, their chart plotter operating system. They also had a great wheel-based autopilot that has been very reliable while underway. Recently, they announced Lighthouse 3 and the Axiom family of chart plotters. I have had the 9″ version of the Axiom for a few days, and these are my first impressions.

Axiom Hardware

Raymarine Axiom 9 box contents

I ordered the Axiom 9″ version with Navionics charting included. I felt this to be a great size increase over my 7″ es75, which was quite small for charts at the helm. In the box you get the chart plotter with cover, manuals and literature, mounting options, and for my model, the Navionics SD card.

New Raymarine logo on cover

This is the first Raymarine product I’ve seen with their new branding – front and center on the sun cover.

Mounting brackets and options

There are the usual trunnion mount and flush mount kits. The flush mount option is a bit different than what I have seen before – the two brackets in the bottom of the picture above sit on the back of the unit inside the hole you cut, allowing for a screw-less install.

Front of Axiom 9″ unit

The front of the unit is one big piece of glass, with a power button in the bottom right of the screen.

Back of unit with ports

On the back of the unit, from left to right, are ports for the RayNet network, USB accessory for RCR-SDUSB card reader, power/network, drain wire screw hole, and 25-pin transducer port.

Above the ports is the SD card cover and slot (the black rubber rectangle). I’m worried about accessibility – I plan on mounting this in a NavPod which will require that I open it up to get to the card when needing to update Navionics, and for downloading screen shots and the like. In addition, there is only one SD slot, compared to two in my es75, which is also disappointing – I use both Navionics and Lighthouse charts on separate cards.

Power and network cable

The power and network are combined into one cable, included with the unit. There are three wires in the power cable – one positive, one negative, and one drain wire. According to the installation instructions, the grey drain wire needs to be sent to a ground on your boat, and then a separate wire back to the drain wire screw on the back of the unit. This is the first time I’ve ever seen a unit requiring a separate ground like this, but it looks like it could be part of a new specification.

NMEA 2000 network port

The surprising thing about the cable is that there is no SeaTalk connector – standard NMEA 2000. Given how much Raymarine focuses on SeaTalk for all of their other products, and that has to be a revenue source for them, it is a surprise to see a standard NMEA 2000 network connection on this cable, but I’m not complaining.

Axiom 9 screen

The quality of the screen is better than my es75 and B&G Vulcan. Clearer picture, easier to see from more angles. That’s one thing that has always frustrated me with B&G – with polarized sunglasses on it has only a narrow field of view. Not so with the Raymarine. This unit has 800 x 480 resolution and 1200 nits of brightness.

Several other vendors have higher resolution panels in products of similar sizes, but I would take a brighter screen, viewable at more angles, and with a much more accurate touch screen over a bit more resolution. While I am looking at charts constantly on this thing, I do most of my planning elsewhere where I would want higher resolution.

The power button is a bit strange – you swipe across it to the right turn the unit on and off, and to pop up a quick menu while the system is running. I’m not sure if this choice was so there aren’t accidental button pushes and to not have a mechanical button for water ingress. Reminds me a bit of unlocking an iPhone.

Overall the hardware is well made, solid chunky build with quite a bit of weight to it. It appears to be the high quality I’m used to seeing from Raymarine.

Lighthouse 3 Software

Lighthouse 3 software update

Lighthouse 3 software update

On first boot, I immediately went in and connected to WiFi to check for a software update. I was offered an upgrade of about 673MB which took a few minutes to download and install. The unit came with v3.0.57 and I upgraded to v3.0.66 (as of June 9th, 2017).

Upgrade weirdness – note the OK box that is across the text. I could not click OK…

After the upgrade I couldn’t click OK to confirm it was updated – I had to reboot twice to get out of the screen weirdness. That’s one thing that I saw in several other places – this is definitely a new product with new software that is … not quite finished.


Main startup screen

This thing is fast! They mention it having a “quad core processor” in the marketing videos, and it definitely does not disappoint. It boots very fast, and has little animations every time you touch one of the main screen icons to launch something. Everything is smooth and quick, no stuttering, and it just feels more modern and up-to-date than most chart plotters as a result of the speed.

The touch screen is also extremely accurate compared to my es-series, and other chart plotters. It is close to iPad accuracy, which is saying a lot, and makes for very quick and easy use.

Chart screens render quickly and clearly

Chart screens render quickly and clearly

Things everywhere are faster, but nowhere did I notice it more than in the charts. Zooming and panning around in Navionics charts is as fast as on a PC using Coastal Explorer – that is a first for me in using chart plotters. My es75 will routinely stutter when moving around in the charts, or simply take a long time to redraw everything. I have yet to get the Axiom to stutter or slow down appreciably.


The other major area of improvement is usability, and you see this everywhere throughout Lighthouse 3. This is what excites me the most about LH3 and the Axiom platform – instead of locking you into specific areas to lay out data, or in one set of settings to use, Raymarine have really thought outside the box and made things more easy for the end user to interact with and customize.

My profiles

A great example is profiles – the ability to setup preferences based on individual users. Useful to adjust things just the way you’d like, and let the next one at the helm setup their own preferences. It also appears to track the amount of time you have been at the helm.

Data overlays

The other one I love is the ability to overlay data on the canvas – charts, radar, etc. Above I’ve added the sea temperature near the top of the screen. Hard to catch in screen shots, but you can resize, move them around, delete, and do all sorts of other things to them.  Gone are “data bars” and other things that take up precious chart screen space all the time, or don’t allow you to move them to where you want them. I think this is my second favorite item in LH3.

Data overlay selection

There’s a bunch of different data bits to choose from, but there are still some missing items compared to LH2 data boxes such as battery amps and the like. Hopefully these will be added back in future software releases.

Quick actions

The other big change usability-wise, and my #1 favorite item in LH3, is the quick actions that have been placed on the various canvases. On charts, there’s a button on the top next to the man overboard button to center the map on your ship, something I have done on my es75 hundreds of times, and it takes two or three clicks/touches – on the Axiom it is one touch.

In the bottom right corner, you can adjust the radar scan range with one touch, again, something that took multiple actions before. Great ways to help me do things faster and easier!

Quick mode selection in radar

There are new, clearer icons to choose modes for the radar as well – another example of usability being carefully thought through in LH3.

Throughout Lighthouse 3 there are many little items that they have done to help with usability, speed to use the system, and general refinements. It feels like a modern operating system instead of something several generations behind.

Below I have some basic observations about major sections and screen shots from each.

I did not test fish finder settings or screens as I don’t have one.

Audio didn’t work for me with my Fusion radio, and I don’t have any cameras.

Audio and camera

What’s Missing?

Auto pilot

There’s no control of my Raymarine EV1 auto pilot, no pop-ups, nothing. This is expected according to Raymarine, but it does limit the ability to use the whole system for navigation.

I was able to create a route and start it, and the auto pilot head did honor track mode and start navigating, but I haven’t tested it through a whole route. There were also some weird situations where the auto pilot alarmed when I was going to a cursor location as if it had lost the navigation data from the chart plotter.  I don’t think any of this is ready for mainstream yet.

Navionics auto-routing

Raymarine has also made it known that this feature is not yet in LH3, but I thought I’d call it out as it is a very popular one. I use it constantly to quickly build out a route when I am out on the water and need to change something. I hope to see it very soon.


Fusion audio does not work quite yet…

According to various posts online, Fusion marine stereos using NMEA 2000 should work with the Axiom, but in my testing it does not. As of 5/16/2017 on the Raymarine Forums here, it has been stated that Lighthouse 3 does not support Fusion at this time, and it looks like this has been prioritized lower than other things.

While I appreciate that it is better to get auto pilot features working, I still consider this feature to be important – we constantly use the chart plotter in the cockpit to skip songs, change volume when needed, and more. It would be a shame if this took 6 months to re-appear in Lighthouse. I have a B&G chart plotter as well, so I can at least continue controlling things.


I am going to be using the Axiom as my primary chart plotter even with the missing features. The usability improvements in Lighthouse 3 along with the larger screen make it far more useful even with those missing features, and I want to see the other new features and functionality that I hope will be coming.  I’ll provide an update on any new features as soon as I get them!


  • Bigger screen / touch accuracy
  • Fast
  • Usability
  • Quick settings
  • Data overlays
  • Improvements in dashboard data / density
  • More settings for radar


  • Drain/ground wire – extra wiring required to ground the unit
  • SD card slot – on the back of the unit, hard to reach
  • Single SD card slot
  • New software – bugs and inconsistencies
  • Missing features – audio, auto pilot, auto routing


About Steve Mitchell

I live in Seattle, WA and love sailing, technology, & playing and composing music. I started playing the piano when I was 3, and ended up figuring out many other instruments along the way. I'm an avid sailor and have a 2000 Beneteau 311 named Grace, and sail it whenever and wherever I can.

  • Mic Fite

    Hi Steve, long time reader, first time reply. I’m a recently retired electrical engineer and have NMEA and ABYC certs. Which is to say that I’m one who really appreciates your thoughtful detailed posts. And especially your project descriptions.

    7 months ago I bought a 2011 Jeaneau. Although the 6 year old suite of Raymarine was serviceable, given my interests and the recent advances in marine electronics I was planning on replacing everything. I was about to go all B&G because of SailSteer and 4G radar. Then Raymarine announced Axiom, and more recently Axiom Pro (yes! thank you). So I REALLY appreciate your detailed Axiom/LH3 reviews (best anywhere)!! Please keep them coming. I am particularly hoping to see new sailing features in LH3, like B&G’s SailSteer; and Doppler capability in the Quantum radar in order to be more on par with Garmin and Furuno.

    I still plan on replacing everything this winter… with Raymarine. So I look forward to your future Axiom/LH3 review updates. Keep ’em coming and keep up the good work!
    Cap’n Mic (s/v Sea Bear lying Anacortes)

    • Hi Mic! Thanks for the kind words. Having those certs must be nice when working on your boat. I am just about to completely redo my main electrical panel with some new BlueSea 360 stuff, similar to my previous boat. Can’t wait to get rid of the older stuff that takes up tons of room, and has few indicator lights as to what is on/off and is a pain to figure out in the dark 🙂

      I did just do the final install of my Axiom and updated the software to v3.1 which I will be posting about shortly. It finally has the necessary bits in it to deal with my autopilot which was holding me back from using it day-to-day.

      According to Raymarine’s website, the sailing features likely won’t be in until early 2018, at least the fancy ones. Not sure about the radar features at this point – should probably go check that out too.

  • I’ve been researching electronics for Y-Not, and the Axiom has been hitting my geek buttons. It is great to see your hand on thoughts.

    I’ve got an essentially blank slate – I need radar, sonar, and an MFD.

    Have you played around with controlling the Axiom from an iPad?


    – Chris

    • Yes I have used the iPad to control the Axiom. It’s not perfect, you still have to use some on screen tools do move things and change stuff, which is a bit odd instead of being able to touch the various icons being re-broadcast. But this is similar to what Raymarine did in their previous attempt on this.

      Other manufacturers have similar challenges. I like Raymarine’s approach hardware wise because they have two chips (or a fancy single one) that can both be a client to a WiFi network for updates, access to online tools, etc. and also broadcasting a WiFi AP so you can join with your iPad.

      Right now I have my Quantum radar paired by WiFi, iPad controlling the MFD, and the MFD itself accessing the ‘net.

      • The dual network setup is confusing – does this mean that the iPad while connected to the Axiom is no longer connected to the internet?

        Is there a way to just have everything work through my current network? It seems as if having two networks is just a recipe for trouble and confusion.

        – Chris

        • Ah yes, sorry for not clarifying that. Most manufacturers of chart plotters do not subscribe to the idea of the device being on an existing WiFi network that you can connect to and access the unit from. Raymarine requires you to connect to a purpose created WiFi network that the chartplotter itself creates for “performance and stability” reasons. Navico (B&G, Lowrance, Simrad brands) has a GoFree product that is a gateway and will connect to your own WiFI network, and you can control their products through your own with caveats. It seems that these manufacturers are skittish about having devices directly connected to an unknown network for some reason.

          • When an iPad is connected to the Raymarine private network, does it act as a bridge to the public network? Or is the iPad locked offline entirely while it is paired? That seems like an insane limitation – so many weather and navigation apps would end up crippled without a net connection. 🙁

          • On the older version of their software, Lighthouse 2, it proxies through the MFD which works but adds some latency. The new version seems to work the same so far but I have had some weird issues.

          • Yes, in my testing, the Raymarine chart plotter has proxied my connections to the Internet through itself. This only works if you have the chart plotter connected to your local WiFi network, of course. I have seen some crazy high latency with this setup, and in Lighthouse 3, their newest which runs only on Axiom hardware right now, I haven’t seen this work reliably.

  • Al Grant

    Might be worth detailing the two versions of the Axiom Pro as well (I think the RV version is just for people who need the Chirp Sonar?) I would also like to see screen shots of the Grib files on the Axiom Pro. I was really interested to read about having to swap networks – a bit of a pain.

    I am looking at using a Actisense unit to connect my old motor to the N2K gauges.

    • Hi Al,
      Would love to cover the Pro, but I haven’t had access to one yet. I only write about things that I have direct access to or have used for a while. I will look at taking some screen shots of the GRIB data.

  • Al Grant

    Also looks like Fusion radios are now supported with the release of Lightouse 3.2

    • Yup, I have been testing v3.2 for a bit now and plan on writing up a new article on that version as well.
