This is SeaVectors

One clear view from planning at home to navigating underway.

SeaVectors keeps the chart at the center. The tools you need are close at hand; everything else stays out of the way.

SeaVectors running on modern devices SeaVectors running on older devices

Fast on new hardware, clean and quiet at the helm.

Still using a trusty 8-10 year old tablet at the helm? No judgment. SeaVectors still runs happily there. Thank goodness for that.
