While we rely more and more upon our electronic charts, they are only as accurate as their source data.
Rocks might not move, but areas are resurveyed all the time – and sandbanks and mudbanks certainly do move, not to mention new buoyage and wrecks which appear all around our coasts – and we need to take advantage of any updates.
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.
The only updates I have ever bothered to install were the free ones that I got with each new unit -- never had any issues.
