How to prepare for the Yachtmaster Offshore exam

The Yachtmaster Offshore exam tests whether you can skipper a yacht safely, and the examiner is looking at your seamanship and your theory at the same time. Here's what to expect, and an eight-week plan to get the theory solid while you build your boat handling.

What the exam actually is

There's no written paper. The Yachtmaster Offshore exam is a practical assessment on a boat, run by an independent RYA examiner. You act as skipper while the examiner watches how you handle the boat, plan and navigate, manage the crew, and deal with whatever they set you, from a man overboard drill to a night pilotage approach. The RYA allows 8 to 12 hours for one candidate and 10 to 18 hours for two.

The theory is tested throughout, by questioning. Expect questions at the chart table, on deck and in the evening, and light and shape cards held up for you to identify. Check the RYA for the current exam syllabus and how to book.

Before you book

Make sure you meet the pre-exam requirements: logged sea time and passages, a valid first aid certificate and a GMDSS radio certificate such as the SRC. Our requirements guide has a sea time checker so you can see where you stand in a minute. Get your logbook signed off and your evidence together early; it's the one part of the exam you can have completely finished before the day.

An eight-week theory plan

Short, regular sessions beat cramming, especially for things you need to recall instantly, like lights and fog signals. Aim for 15 to 20 minutes most days, and keep going back over earlier weeks as you add new topics.

Boat handling: the part revision can't do for you

Revision covers the theory, but much of the exam happens on the water. Before the exam, get as much time as you can actually skippering: berthing and leaving in different wind and tide, picking up a mooring, recovering a man overboard under sail and under power, and briefing and managing a crew. Many candidates book a prep week with a sea school immediately before the exam, so the boat and the area are familiar.

Practise passage planning as a skipper would: tidal gates, a plan B, and a pilotage plan you can follow at night with a head torch and no chartplotter.

On the day

  • Bring your logbook and evidence of sea time, and your first aid and radio certificates.
  • Brief your crew properly before you leave the berth. Safety briefings are part of being skipper.
  • Think aloud. The examiner can only assess the decisions they can see you make.
  • If something goes wrong, say so and fix it. Recovering well is seamanship too.
  • When you don't know an answer, say how you'd find out, from the almanac, the chart or the pilot book.

After you pass

To use the certificate professionally, you'll need a commercial endorsement. If you're building a career on superyachts, our guide for superyacht crew covers what that involves and how big-yacht sea time counts.

Questions

Is there a written exam for Yachtmaster Offshore?

No. It's a practical exam on a boat with an RYA examiner. The theory is tested by questioning throughout, at the chart table, on deck and often in the evening.

How long should I revise for the Yachtmaster Offshore exam?

Most candidates need several weeks. Short daily sessions over about two months, covering the collision regulations, lights, buoyage, tides, passage planning, safety and weather, work better than cramming the week before.

What should I bring to the Yachtmaster exam?

Your logbook and evidence of your qualifying sea time, a valid first aid certificate and a GMDSS radio certificate such as the SRC. Check the RYA's current requirements when you book.
