Safe navigation
with CIO+ StayAway Areas.

The poor position accuracy of charted obstructions has played a certain role in grounding incidents of vessels for many years.

For this reason, ChartWorld has developed an additional CIO+ layer based on new technologies that overlay highly accurate satellite images with information from below the water surface on top of ECDIS systems.

This provides mariners with the most accurate information on shoals and underwater obstructions that may not be accurately represented on current charts.

The new StayAway Areas from ChartWorld give mariners a more complete perspective.
