    E-nav on the cheap

    Another reason that OpenPlotter is maturing nicely - there are other people who have worked out many of the kinks for you. https://sailoog.gitbooks.io/openplotter-documentation/en/sdr-receiver.html Haven't tried this myself... I have AIS coming from my Standard Horizon radio onto the N2K network which then comes into the Pi from the Arduino CAN interface -- Signal K then translates it into NMEA 0183 messages which OpenCPN (either on the Pi or right on the laptop) likes.

    @Passport111 One speedbump you might encounter installing Linux could be storage space. It's only got 32gb of eMMC... but with a decent USB 3.0 flash stick, you can see how things perform. One option would be a real USB 3.0 SSD. See what works!

    True that. However I don't want the owner's demerits to reflect too poorly on the boat... The deathtrap offset companionway, however....

    For the committee's review, I present AIDA, which we saw during a race this weekend. She came motoring up the channel and into the anchorage; we took a look at her sitting happily in the Essex, CT mooring field when returning.

    OpenPlotter running on my little RPi has not left me high and dry... yet...

    All really good points, Paul. FWIW, that Raspberry Pi 3B+ is plenty powerful enough to handle sensor data (N2K interface, conversion, multiplexing, Signal K server) and run (headless) OpenCPN 24x7... I usually see CPU usage under 10% in this mode. It's also definitely not the right choice for web browsing, photo or video editing, etc. Everyone's needs are different, and there are lots of tools out there. Mix and match to find what's right for you!

    I was surprised that someone really wants actual US dollars in exchange for this beauty, let alone 4,500 of them which should be enough dollars to buy a totally serviceable used Honda Civic: https://hartford.craigslist.org/boa/d/1987-oday-272-le-4500-obo/6688254654.html

    For what it's worth, I've been playing with several of these solutions on Gemini, so I'll share some thoughts and experiences. First, I've had great luck playing with a Raspberry Pi 3 B+ and OpenPlotter. I like that OpenPlotter has quite active development right now, and does a really good job integrating to my networks. I'm using a CAN-USB interface to hook up to my N2K network, and also picking up a few pieces of data that aren't on N2K from a USB-RS422 interface from NMEA 0183. One nice advantage to this is that I can leave the Raspberry Pi running 24x7 and its draw is completely negligible. I can also run OpenCPN on it drawing no more power, and save all of my tracks. I run the Pi headless. http://www.sailoog.com/openplotter For the CAN-USB interface, there are a ton of options out there right now. I'm using a homegrown one with a Teensy 3.2, a CAN transceiver chip, and some miscellaneous resistors and capacitors. Works just fine for me. Mine is built to this schematic, minus the extra USB interface: https://github.com/ttlappalainen/NMEA2000/blob/master/Examples/TeensyActisenseListenerSender/Documents/Teensy_Actisense_listener_sender_schematics.pdf But it's not opto-isolated, so to do it right, I should probably either buy the one offered by the OpenPlotter folks, or find an isolated CAN-USB stick on fleabay. In my current application, I interface to the N2K network in "receive only" - I'm not sending data back to the network. That's a possible future development. A nice upgrade for this might be adding a real SSD to the Pi and using that for all of my data storage next year, rather than the MicroSD and USB stick solution I'm using today. Hmmm... When I need to, I just use my laptop and VNC to look at the plotter - can also view on my phone/tablet using VNC apps. I really want to get rid of the laptop, though - it draws too much power, is old, and I am growing to rather dislike it. If I were to do it right now, I'd get one of these for web browsing, managing the OpenPlotter, or even running OpenCPN directly: https://www.geekbuying.com/item/Beelink-S2-Gemini-Lake-N5000-8GB-128GB-Windows-10-Mini-PC-398011.html Monitors, I've found, are a very individual decision. I haven't made my mind up. I'm wavering between an inexpensive 21/22" LED "desktop" monitor (and I'll look around to find one that has a good DC input which I can hook into a voltage converter from the boat's 12v panel) or possibly a USB-powered display something like this: ASUS MB169B Overall, I really like having the Pi do my interface, multiplexing, OpenCPN, etc etc since it can run 24x7, sits on my boat's ethernet, N2K and NMEA0183 networks, and uses almost no power. YMMV, batteries not included.

    Back in the day, Ginger was something. But Ginger and Mary Ann didn't age the same: Of course, it seems that the boat in question seems to be named Mary Ann but aged a bit more like Ginger...

    Congratulations! Mine is a Mk II - they're all great boats. You'll love it.

    Interesting boat - the current owners haul her in the same yard that I do each winter, and I've seen her up close. The fog horns on the mizzen are pointed nearly exactly at the skipper's brain. But I dig the fully-battened mizzen - not the poor in-mast-furling roachless main. Very solid-looking boat.

    Bad phone camera photo. But interesting concept - a Whitebred 60 on the left, and America II on the right. And probably something cooler in the water in the background, but I was in a rush and didn't get out of the car to investigate.

    C&C 36...will it float?

    The PO of Gemini made some changes before we bought her. 40 gal fresh water, and 80+ (!!!) holding tank. Really? Why do I need that much holding tank? Way too much work right now to even contemplate a change, however. I'd much rather have the ratio reversed.
