During the summer 2015, I participated in FTLF/DOCA's Baltic Rally 2015, visiting all ten countries surrounding in the Baltic Sea; from mid June to early september.
(FTLF/DOCA is the Danish Ocean Cruising Association founded in 1985).
During this trip, I had access to paper charts, and the following android apps: Seapilot, Plan2Nav, and Navionics on my tablet/mobile, a chartplotter
charts, and a C-Map
card reader and the software
- SOB, and OpenCPN (with old C-Map charts) on my Win-7 ThinkPad.
That gave me a lot of back up, and I like to try different brands ...
You may want to take a look at Seapilot - https://www.seapilot.com/
As of today, they offer official electronic charts of all countries in the Baltics - except for Kaliningrad, Lithuania and Poland
. They offer a free app for android, but not cheap
maps, though. Check it out for yourself ... at https://www.seapilot.com/
They offer a 36 hour free trial period ...
Plan2Nav uses C-Map 4D charts - I used EN-I299 - Baltic Sea and Denmark, that covers all relevant countries. The app is free. You buy the charts. See PLAN2NAV
I also have Navionics Europe
covering the same countries (except DK) ...
Furthermore, I have a card reader for my PC, using the SOB applikcation (Software On Board). I can use the same C-Map MAX charts on the C Card for my card reader for the PC, *and* for my chartplotter
- EN-M019.35 - NORTH AND BALTIC SEAS - Mega Wide - covering all Nordic
countries - except Iceland
As I'm used to using C-Maps on my plotter and PC, I tend to prefer these charts. I did not, however, experience major differences in quality between the charts from the three different above mentioned vendors.
Which app/program one prefers, is mainly a matter of "taste and habit", I suppose ...
Personally, I prefer to use my chartplotter in the cockpit
as it is very bright and waterproof, and easy to operate ... The other instruments were back up.
