I have about $1000 worth of Navionics
electronic cartography on my boat. Three of the Micro SD cards have Freshest Data subscriptions, two of which are expiring soon.
In years past, I used to be more casual about keeping electronic charts
updated, than I am these days. I have used the Freshest Data a lot and have been glad I did, although even with this service
there are plenty of deviations between chart and reality -- not all of the individual charts
which go into one of these chips are updated all that often. But at least I think all the Notices to Mariners, at least, are incorporated, so main changes to buoyage, channels, etc.
So now the question arises as to whether to continue Freshest Data, or not. The two cards which are expiring will not be used much this year as I'm in the Baltic
until the end of summer. I have just updated them and that is plenty fresh enough (in my book) for the little use I will get out of them this fall.
So maybe I'll renew these subscriptions just before summer next year? That puts me a whole year ahead of the game
, with coverage then good for a whole year after that.
Or do they not allow you to start up Freshest Data if you've let it expire?
Anyone have any experiences or knowledge or tips about this?
One more thing: The last Navionics
card I bought has a new system where you can't just download the whole set of charts at once. You have to choose an area. What a PITA, especially when working on a slow connection! You can't tell which areas you've already downloaded, and just have to guess! I have traversed the entire Baltic
from one end to the other, and I needed the entire chart collection. I ended up with gaps! What a terrible system. Instead of choosing some random area with the mouse, they should (if they must divide the chart area into sections) define different areas and let you see clearly what you have and what you don't have -- by the way, the Navionics charts in INavX
are done that way and it works fine.
