Frequently Asked Questions

Day Skipper Revision is an interactive study tool built around the RYA Day Skipper theory syllabus. It covers all 17 modules with learning content, quizzes, spaced-repetition flashcards, and interactive visual tools for the hardest topics like tides, COLREGs, and compass work.

No. Day Skipper Revision is an independent study aid. It is not affiliated with, endorsed by, or connected to the Royal Yachting Association (RYA) in any way. The content is based on publicly available nautical standards, regulations, and widely taught sailing theory.

No — this is a revision companion, not a replacement. The RYA Day Skipper theory course covers practical chartwork exercises, instructor-led teaching, and assessment that this tool cannot replicate. Use this alongside your course to reinforce what you've learned and identify areas that need more work.

There are 17 modules covering the full Day Skipper theory syllabus: Nautical Terms, Safety, Marine Environment, COLREGs, Pilotage, Compass, Visual Aids, Tides, Chartwork, Position/Course/Speed, Charts & Publications, Meteorology, Passage Planning, Restricted Visibility, Ropework, Anchorwork, and Drawing Instruments.

Six modules include interactive visual tools built specifically for the hardest exam topics:

• Buoyage Trainer — learn and quiz yourself on IALA Region A buoy marks with day/night views

• Lights & Shapes — identify vessel navigation lights under COLREGs

• Compass Converter — practise True/Magnetic/Compass conversions with the CDMVT mnemonic

• Tidal Curve Trainer — step through tidal height calculations with an interactive curve

• Vector Triangle Builder — visualise course to steer calculations with a practice mode

• Forecast Decoder — decode shipping forecast terminology with the Beaufort Scale

3 modules are completely free (Nautical Terms, Safety, and Marine Environment). Full access to all 17 modules, interactive tools, and mock exams costs a one-time payment of £4.99 — no subscription, no recurring charges.

We recommend working through the modules in order, as they build on each other. For each module: read the learning content first, then test yourself with the quiz, and use flashcards for ongoing revision. Use the interactive tools for the topics you find hardest. Take the mock exam when you feel ready — aim for 85% or higher.

The flashcard system uses the SM-2 algorithm to schedule reviews at optimal intervals. When you rate a card as "Easy", it won't appear again for a while. Cards rated "Hard" or "Didn't know" come back sooner. This spaces out your revision so you review material just before you'd forget it — the most efficient way to move knowledge into long-term memory.

The mock exam randomly selects 30 questions from across all modules. It's timed (aim for under 45 minutes) and gives you instant feedback after each question. At the end, you receive an RYA-style grade (Good, Average, Fair, or Poor) along with a breakdown of your performance by topic, so you know exactly where to focus your revision.

On the real RYA assessment, a "Good" or "Average" grade is a pass. In our mock exam, that corresponds to roughly 70% or above. We recommend aiming for 85%+ to give yourself a comfortable margin.
