Simplify media updating
There’s even more need to update electronic charts than paper charts, especially as chart plotters display your position to a few metres on the chart and people sneak ever closer to obstructions, believing their charts and position to be accurate to the nearest centimetre.
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.
These companies offer their cartography on memory cards for plotters and each sell their own i Pad and Android tablet apps, which are much cheaper.
Navionics Navionics are the only company to offer daily chart updates.
