RYA Day Skipper theory is the Royal Yachting Association’s shorebased course in navigation, seamanship, weather, tides and the collision regulations for people who want to skipper a small yacht or motor cruiser in familiar waters by day. It is open to anyone with no minimum age, takes around 40 hours plus exam time, and can be studied in a classroom, online or by distance learning. The course ends with written assessment papers, usually one on chartwork and navigation and one general paper, and the RYA recommends completing it before the Day Skipper practical course.

Who the Day Skipper theory course is for
Day Skipper theory is usually the first serious navigation course people take. It suits crew who want to move from following instructions to making the decisions, new boat owners, and anyone planning to charter a yacht. The RYA describes it as a fuller course recommended for inexperienced skippers and for anyone thinking about the Day Skipper practical.
The practical course is hands-on, with very little time to teach navigation on board. Before it starts, the RYA expects your theory knowledge to be at Day Skipper shorebased level, and you are assessed on that knowledge during the week afloat. Taking the theory first means you can spend the practical actually skippering rather than learning to plot.
Why the certificate matters later
| Topic | Details |
|---|---|
| Commercial endorsement | To have a Day Skipper practical certificate commercially endorsed, the RYA requires it to be supported by a Day Skipper (or higher) shorebased completion certificate, with final exams invigilated in person. If you study online and might want this, tell your centre when you book. |
| Cruising abroad | The Day Skipper practical qualification lets you apply for an International Certificate for Operators of Pleasure Craft (ICC). |
| Next steps | The Coastal Skipper/Yachtmaster Offshore theory course expects knowledge to Day Skipper shorebased level. |
What the Day Skipper theory syllabus covers
The RYA lists these main subjects:
| Topic | Details |
|---|---|
| Seamanship | The core knowledge a skipper needs to run a small vessel safely, including safety equipment and emergencies. |
| Chartwork | Chart symbols, latitude and longitude, measuring distance, and true and magnetic bearings. |
| Position fixing | Bearings, transits, estimated positions and GPS. |
| Plotting a course to steer | Allowing for tidal stream and leeway. |
| Electronic charts | Using chartplotters and apps sensibly alongside paper. |
| Tides | Heights and times at standard ports, tidal streams and tidal stream atlases. |
| Coastal navigation and pilotage | Buoyage, lights and planning a harbour entry. |
| Weather forecasting and meteorology | Where to get forecasts, what the terms mean and how weather systems affect a passage. |
| Collision regulations (IRPCS) | Who gives way, plus the lights, shapes and sound signals you are likely to meet. |
How the Day Skipper theory assessment works
There is no national multiple-choice test. Instead, training centres set the RYA assessment papers at the end of the course, and you complete them using the same training charts and training almanac you have practised on. Centres commonly describe two papers:
- Navigation and chartwork paper: plotting positions, working out a course to steer, estimated positions and tidal height and stream calculations.
- General paper: seamanship, safety, passage planning, meteorology and the collision regulations.
Time allowed, pass criteria and resit arrangements are set by the training centre and vary, so ask before you enrol. You will need a plotter or protractor, dividers, soft pencils and an eraser; ask your centre whether a calculator is allowed. The RYA training almanac is for training only and must never be used for real navigation.
A simple study plan for Day Skipper theory
The 40 hours go quickly, especially on an intensive week. A plan like this keeps the hardest topics from piling up at the end:
- Before the course: learn basic boat terms, the 32 points of the compass and the IALA A buoyage shapes and colours. These are pure memory work and free up class time.
- First third: chart symbols, latitude and longitude, measuring distance and converting between true and magnetic. Get fast and accurate here, because every later exercise depends on it.
- Middle third: tides and tidal streams, then estimated positions and course to steer. Practise a tidal height and a course to steer every day.
- Final third: pilotage, weather, IRPCS and safety, followed by full timed practice papers.
- Exam week: revise lights and buoyage with flashcards and redo any exercise you got wrong.
Day Skipper theory practice questions
Try these five original questions, written at Day Skipper level. Deviation can be ignored unless stated.
Question 1
In IALA Region A, you see a mark with two black cones pointing towards each other. On which side should you pass it?
- A. To the north of it
- B. To the east of it
- C. To the south of it
- D. To the west of it
Answer: D. Cones point to point is the west cardinal topmark, and safe water lies to the west of a west cardinal. At night it shows nine quick or very quick white flashes.
Question 2
Low water is at 0300 with a height of 0.8 m and high water is at 0900 with a height of 4.4 m. Using the rule of twelfths, what is the approximate height of tide at 0500?
- A. 1.4 m
- B. 1.7 m
- C. 2.0 m
- D. 2.6 m
Answer: B. The range is 4.4 − 0.8 = 3.6 m. In the first two hours the tide rises 1/12 + 2/12 = 3/12 of the range, which is 0.9 m, so the height is 0.8 + 0.9 = 1.7 m.
Question 3
You take a bearing of a church spire of 245°M with a hand-bearing compass. Variation is 4°W. What true bearing do you plot on the chart?
- A. 236°T
- B. 241°T
- C. 245°T
- D. 249°T
Answer: B. Going from magnetic to true, add easterly variation and subtract westerly variation. 245 − 4 = 241°T.
Question 4
Two sailing yachts are converging with a risk of collision. Both are on starboard tack, and your yacht is to windward of the other. What should happen?
- A. You keep out of the way of the other yacht
- B. The other yacht keeps out of your way
- C. Both yachts alter course to starboard
- D. The larger yacht gives way
Answer: A. Under Rule 12, when two sailing vessels have the wind on the same side, the windward vessel keeps out of the way of the leeward one. Size makes no difference.
Question 5
A shipping forecast gale warning for your sea area says the gale is expected “soon”. When does that mean it should arrive?
- A. Within 6 hours of the time of issue
- B. Between 6 and 12 hours from the time of issue
- C. More than 12 hours from the time of issue
- D. Within 24 to 48 hours
Answer: B. The Met Office uses “imminent” for within 6 hours, “soon” for 6 to 12 hours, and “later” for more than 12 hours after the time of issue.
Tips from the syllabus
- Label every line you plot. Use the standard arrows for water track, tidal stream and ground track so you, and the marker, can follow your working.
- Read the latitude scale for distance. One minute of latitude is one nautical mile; never measure distance on the longitude scale.
- Check spring or neap first. Before using a tidal stream atlas, compare the day’s range with the spring and neap ranges, then interpolate the rate.
- Use the right reference port and hour. Many tidal errors come from using the wrong high water time.
- Answer the question asked. If the paper wants a magnetic course, do not stop at true.

Frequently asked questions
Is there an exam at the end of Day Skipper theory?
Yes. The course finishes with written assessment papers, usually a chartwork and navigation paper and a general paper covering seamanship, weather, safety and the collision regulations. The RYA states the final exam is invigilated at an RYA training centre, whether you studied in a classroom or online.
How hard is the Day Skipper theory exam?
Most people find the chartwork and tidal calculations the hardest part, because they involve several steps and careful plotting. The rest of the syllabus is more about learning and applying rules, such as buoyage and IRPCS. With regular practice through the 40-hour course, the papers are achievable for a complete beginner.
Do I need Day Skipper theory before the practical course?
It is not compulsory, but the RYA recommends taking Day Skipper theory before the practical course. The practical course expects navigation and theory knowledge at Day Skipper shorebased level and assesses it on the water. Doing the theory first lets you focus on skippering during the practical week.
How much does Day Skipper theory cost?
Course fees are set by each RYA training centre and vary with format, location and what is included, so compare current prices directly with providers. Ask whether training charts, the training almanac, course notes and the invigilated exam are included. The RYA’s Day Skipper Shorebased Notes are currently listed at £14.99 in paperback on the RYA shop.
Can I do Day Skipper theory online?
Yes. The RYA confirms the Day Skipper theory course can be taken in a classroom, online or by distance learning. If you might later want a commercial endorsement, the final exams must be invigilated in person, so tell your training centre when you book.
Does passing Day Skipper theory let me skipper a boat?
Passing the theory gives you a shorebased course completion certificate, not the Day Skipper practical qualification. It is the practical qualification that lets you apply for an International Certificate for Operators of Pleasure Craft (ICC). The theory certificate is still valuable, as it supports a commercial endorsement and prepares you for the next level.
