Your call?

OOW Simulator puts you on the bridge of a container ship: radar and ARPA, the COLREGs, lights, anchoring, man overboard and fire. Every mistake is explained with the Rule behind it. Prepare for the exam the way you will keep a watch.

Who it is for

From cadet to officer of the watch

Built for cadets in training and for ratings who want to become officers. Practise the core skills of a junior navigator, build confidence and sharpen your actions in emergencies.

The problem

Simulator centres

Hours on a full-mission simulator are expensive, and finding time between contracts is hard.

The problem

On the bridge at sea

At sea you rarely get to handle the ship yourself, and the right situations to practise may not come for weeks.

The problem

Dry theory

No dull manoeuvring boards or rote learning. You handle the ship and see the result of every decision at once.

What you get

  • The core skills of a junior navigator: radar, ARPA, COLREGs, lights and signals
  • Confidence in your decisions, built through repetition
  • Practised actions for man overboard, fire and equipment failures
  • Confident use of navigation equipment on any ship’s bridge
  • The chance to show the Master you are ready to keep a watch on your own, and a step towards promotion
