Go weather not updating
But unlike paper charts, you can’t simply draw on the electronic versions. Digital charts are available in a variety of formats and with hugely varying levels of complexity and price. You can just buy a new chart each time, but this can work out to be extremely expensive, so it’s worth putting in some time to research the options which are open to you.
Chart plotters There are three main providers of charts – Garmin (Garmin Blue Chart) Jeppesen (C-Map) and Navionics.
Older charts Garmin say that their older charts on cartridge-type flash cards (called Traditional Blue Chart) will be discontinued as of December 2014 (these stopped being supplied with new plotters in 2008).
Watch this space for information on future support. C MAP C-Map offer a range of update and upgrade options for their customers. Their charts fall into the following categories: NT (for older plotters) and MAX, MAX Pro and 4D.
