My crew is budding Pi hacker and would like to play around with OpenCPN. Is there any way of getting UKHO charts to suit? I though the VMH ones might work, but I see that they are Windows only.
UKHO Charts for OpenCPN on Raspberry Pi

Many thanks. Any less convoluted and dodgy-looking sources?

O-charts are great and easy to use , download the resource for opencpn for their charts , follow the link and pay and then refresh you chart list on the O chart resource on OPEN CPN The charts are then there , they are very good and clear and as with OPENCPN You can take out the clutter or add to them

Relax! O-charts are not dodgy. They have formal agreements with all the HO's whose charts they offer. AFAIK the scheme was largely developed and set up by Dave Register, the OpenCPN lead developer.

Think Ocharts have close links to the openplotter project. But definitely not dodgy. Just released is a USB key so you can share between machines instead of only having one machine and one backup.

For a play the cm93 charts are usually not hard to track down online.

As others have said: dodgy looking but not dodgy. They pay a proper licence fee to the uk hydrographic office under the same type of agreement (if I understand correctly) as vistmyharbour. Not sure how far Dave Register was involved if at all (North Americans get free charts from their hydrographic office) but certainly the lead developer on openplotter works part time with these folks who are, I believed, based in Barcelona.
There's been no unusual activity on the credit card I used to buy my charts form them either.

I've also used UK O-Charts with Open CPN (albeit the PC version). They're fine, although I confess to preferring the raster charts by VMH.

OK, everyone, many thanks for the reassurance. The whole website has a "Russian pirate" look to it, which is what worried me. Good to hear that many people have used it.

Likewise I use them on opencpn. The only problem I have is that I can't make the depth figures big enough to read.
I have a laptop with vmh on standby sometimes if I'm not sure.

You could try changing the chart object scale factor in the user interface options to increase the sounding font size. Works with cm93 vector anyway.

A wee update: he is still trying to get OpenCPN working on a Pi. Two of the dependencies for the one at http://www.agurney.com/raspberry-pi/pi-chart [*] are unavailable, and the OpenPlotter SD card image failed to boot, though the download zip had the right sha1 hash. So he's on to Plan C, which is the OpenPlotter version of Noobs.
Coming from the nice, easy world of Xubuntu on desktops and laptops I am constantly amazed at what a bloody pain everything to do with the Raspberry Pi seems to be. Still, I suppose it's a bit unfair to complain that a hobbyist computer is fit only for hobbyists.

Sounds very likely that it's hardware problem your end. The openplotter image works.
Maybe dodgy card, dodgy power? But very likely the issue is your end.

Installed Raspbian.
Added correct repo to the sources.list
apt-update && apt-get install opencpn
Worked just fine.

Did you try the openplotter image? Everything preinstalled plus the wonderful signalk.

Either just copy the noobs files onto a blank sd card (or usb pendrive is a PiB+) or burn the img using something like win32 disc imager.

The majority of Pi problems seem to stem from a power supply which isn't up to the job, draws little compared to what it can do but the power draw spikes now and then. The Pi itself and the software are well up to the multitude of very useful jobs it can do onboard, can't think of any out of the box software that comes close.

No, because I was initially on the beta/testing release of V5
Is OpenPlotter raspbian based?

Yes, openplotter is raspbian with opencpn installed, the wonderful signalk, the also wonderful from one of our own Kplex to do the multiplexing plus various other bit like node-red/mqtt and the openplotter python code so a nice easy user interface to make setting up easy.
Version 2 imminent which sounds like quite a major rewrite with much better documentation.
Signalk does much of what was in openplotter originally.
I've had a pi running 24/7 for must be a few years now, really come of age now doing so much onboard.

Yes, it sounds like it is there.
I was about to install, and indeed had purchased, a Raymarine plotter over the winter, but the staggering cost of the cables was beginning to irk me, the £250+ for the charts was the final straw.
OpenCPN is fine from what I can see, I've had it running on a pi and touchscreen for ages now, just putting together a larger mount for a 17" screen for "down below". I would have made more progress, but I got distracted building an AIS transceiver from scratch ...

The card was a nice new SanDisk one, but I'll have a look. The Pi hasn't shown any sign of dissatisfaction with its power supply before. I am told that when booted with the OpenPlotter image, one green LED lit up and that was that. It's a Model 2B+, I think. We have a 3B+ waiting in its box.
What repo did you use?
That's what we tried, using dd to transfer the image.
We'll recheck the power issue. I have a USB current meter which may be useful.
