Re: Charts and Chartplotters

I have been playing with OpenCPN for the past couple of weeks. It is still clunky and slow compared to PolarView NS, but the price is good and it really is flexible. Chart downloads and updating in OpenCPN has been VASTLY improved from what it used to be, but it still does not match PolarView's interface for selecting charts, or the granularity with which they can be selected. I am updating ny NOAA charts in PolarView as I type.

It is a shame that Polar Navy is closing down in 2 days from now. It was a GREAT chart plotter program - fantastic for route planning. I will continue to use it until it breaks. I am glad that my PolarView 2.7 license on my Windows XP PC is still good, and the 3.0.8 license on this Windows 10 PC is working well and allows me to download chart updates. I had been using this PC to update the charts, and then I would transfer the updated charts to the XP PC. Once PolarNavy chart updates are no longer available I will either update my charts using OpenCPN, or simply download from the NOAA site, and load into PolarView NS.

Here (for my own reference) is how to update charts in PolarViewNS WITHOUT using the Charts Manager (perhaps someone else will benefit):
Within PolarView you have defined a chart location. Go to the Download Manager to see where this is.
1. Create a TEMP directory to download .zip files into.
2. Go to and pick either ENC (Electronic) or Raster (printed format) charts (or both).
3. Go to the ENC/Raster "Listing" link, and select the charts that you want to download (ALL, by CG Districts, by State, by Region, or individually). Download of a .zip will start when you make your selection. Download to your TEMP directory.
4. Open the .zip file, and you will see that it contains directories.
5. Copy the directories into the defined chart location that PolarView is using.
6. (Re)Start PolarView and the charts and chart database will update automatically.

Re: Charts and Chartplotters

Although I have a PC on board I wouldn't use a software plotting product because I suspect they are in biz on day and gone the next.

pay attention... someone's life depends on it
