How OpenCPN and SignalK Replaced Our Expensive Navigation Software

[@thats-no-moon]

GREAT setup, I would love to see a couple of in-depth videos on this.

I'm very new to sailing. At present I only have a sailing dinghy though I'm planning on getting a pocket cabin cruiser. I've also been a Linux user for 3 years. You have no idea (or maybe you do) how happy it makes me to seeing Linux used this way. You're so awesome!

[@TrimaranSpiritXL]

Brilliant video thanks for sharing! love the OSS setup it’s hard to beat it and it’s clear that it’s the direction everything is heading towards. Hard for software companies to compete with a passionate OS community that knows what’s needed within the UI and UX. B&G and Simrad will soon be hardware only manufacturers making sensors that plug into these types of setups. We saw you guys in Vista Mar Panama I think?

[@HollyandRay]

Hey! Thanks for watching! Yeah, there are just so many great free options out there that are better than what's offered by B&G, Raymarine, etc. Between OpenCPN and qtVlm, we don't need any of the other offerings. Yes, thank you so much for bringing the block for our main halyard to us! 😀

I would like to see more on this. For instance what can it NOT do? Looks like you have radar displayed. How about anti collision sonar? Exterior camera feeds? More on the hardware too?

[@HollyandRay]

[@peterhagen7258]

I've had OpenCPN on my last 3 laptops. I use a Serial/USB connected GPS antenna (Several brands Under $100, including Garmin) which is smaller than a mouse. I used it as a backup/secondary chart plotter for several deliveries (US Coastal) .Since I can add more interfaces to the laptop, I can store the charts and tracks on a separate disk, thumbdrive, etc. (or NA-based disk) I can have all the data backed up and even use any other PC on-board. It also lets me do voyage planning anywhere I can have my laptop. You could also add a 2nd monitor and mount it remotely as a duplicate of the main screen to have the display in 2 places. P.S. all of the U.S. charts are free to download and the process to DL or update is pretty painless, but the post-DL process can take a little while (it's not instant) You can runi it on multiple platforms and transfer waypoints, routes or recorded tracks back & forth.

[@phildolling8348]

Really love what you have done. You have gone beyond what I have managed on my Lagoon. I only got the OpenCPN, Signal K, KIP and Grafana items working. I am very interested in how you linked to the B&G (and yes I agree, I also used OpenCPN to avoid spending $5,000 on another B&G display). I currently use RPi - do you think the NUC is more versatile? Thanks

[@HollyandRay]

Hey Phil, thanks! If all you want to do is view the B&G, that can easily be done with network streaming. However, if, like us, you wish also to control it, we’re using a Python script to accomplish that. With everything that we’re doing, for us to maintain a very responsive system, we needed to use the NUC. However, the RPi is great for collecting data!

[@phildolling8348]

@@HollyandRay I will definitely look into that as I would love to control the Zeus from the nav station. I may tap you up for more info if you don't mind, but it gives food for thought and a good winter project :)

[@SailingNoRegrets]

Great video. I was looking at the B&G ZC2 unit control from our nav desk, how are you controlling your plotter from the touchscreen? Is this possible? I thought I was stuck with the clunky rotary wheel on the ZC2.

[@HollyandRay]

Thanks! :) We’re using a python script to control the B&G from the touchscreen, which is connected to the same network as the Zeus.

[@SailingNoRegrets]

@HollyandRay how on earth did you find or develop that? Can you please point me in the right direction. We're getting our new boat sorted and controlling the Zeus by touch not the ZC2 rotary dial would be much better. I've sent you a message through IG if that's better

[@Tb0n3]

On most of my machines that I use for gaming I run Arch. It's very poorly supported because there's no native build so it has to be built from source. Thanks to that, all the plugins have to be built from source too and many of them are outdated. I suppose the bleeding edge nature of arch isn't needed on a chart plotter like it is for games. I believe you said Debian. Does Debian seem to have all the features you need for both opencpn and media?

[@HollyandRay]

Hey, thanks for watching! Debian is very well supported but Ubuntu would probably be best. We had a couple issues with Ubuntu and our touchscreen but debian worked well. OpenCPN, while we do have it, isn't what we use now. We are now using qtVlm and find it much better for our use.

[@Tb0n3]

@@HollyandRay what was your reasoning for changing? It seems to me like opencpn isn't getting much development anymore. Maybe depreciated is that why? Open CPN seemed nice because it was very extensible is qtvlm just as versatile?

Thanks for rhe vid that looks like a great system that I'm sure took many hours to build. I have a Raspberry pi 4 system for chartplotter and monitoring which is basic compared to this but works well. Re the comments about needing to be developer and know charting I say just give it a go. There's heaps of resources online and people happy to help. I built my system with zero coding. If you install the latest copy of openplotter it includes opencpn so most of the config is done for u. Read the manuals, watch utube vids and just start. Join the online communities and they will help. Re the comment about charting. If you own a boat you should know how to read a chart and navigate if not take a course, no matter how good your electronics are you can't rely on them 100%.
