Day Skipper Theory

Navigation and Chartwork

• Understanding chart symbols, buoyage systems (IALA A), and types of charts.
• Measuring distances and bearings using dividers and parallel rulers.
• Plotting positions using latitude and longitude, and determining compass bearings.
• Variation and deviation: understanding magnetic influences and applying corrections.
• Course to steer and estimated position (EP) calculations, including leeway and tidal stream.

Tides and Tidal Streams

• Reading tide tables to calculate height of tide and tidal range.
• Using tidal diamonds and stream atlases to assess currents and plan accordingly.
• Applying tidal curves to determine safe passage times in drying or restricted areas.

Meteorology

• Understanding weather systems, fronts, and pressure patterns.
• Reading synoptic charts and interpreting shipping forecasts.
• Cloud types, wind shifts, and weather indicators relevant to small boats.

Rules of the Road (COLREGs)

• Key navigation rules for preventing collisions: responsibilities between different types of vessels.
• Lights, shapes, and sound signals used in day and night navigation.
• Practical application of rules through scenario-based learning.

Passage Planning and Pilotage

• Constructing a pilotage plan for entry and exit from harbours.
• Passage planning using tidal data, weather, and hazards.
• Log keeping, estimated arrival times, and contingency planning.

Safety and Seamanship

• Understanding safety equipment and emergency procedures.
• Anchoring techniques and considerations.
• Basic ropework, including knots and mooring lines.

Assessment

The course concludes with two written assessments: one on chartwork/navigation and one on general seamanship and theory. Successful completion is required before progressing to the RYA Day Skipper Practical course. Many centres provide support and extra time if needed.

Most adventuro training partners offer this course in a variety of formats – from classroom-based intensives to flexible online options – so you can find one that suits your schedule and learning style.

Completing the RYA Day Skipper Theory course enables you to:

• Understand and apply the principles of coastal navigation and pilotage in daylight and limited visibility.
• Read and interpret nautical charts, tide tables, and weather forecasts to plan safe passages.
• Recognise and apply the International Regulations for Preventing Collisions at Sea (COLREGs).
• Progress to the RYA Day Skipper Practical course in either sail or motor format, which can lead to qualifications accepted for chartering vessels in many countries.
• Make more informed decisions onboard, increasing the safety and enjoyment for both crew and skipper.

Once you complete the theory course, you’ll be better equipped to skipper a vessel in familiar waters by day and begin building experience for more advanced qualifications like Coastal Skipper and Yachtmaster. Many adventuro-listed providers offer both theory and practical training – making it easy to plan your next step.

• You should have basic boat handling experience under sail or power.
• Some familiarity with nautical terms and coastal navigation is helpful.
• No formal qualifications are required before starting the theory course.
• Recommended: RYA Essential Navigation and Seamanship course or equivalent experience.
• You should be comfortable with basic maths, especially working with angles and time.
• Minimum age is usually 16, though this may vary by training centre.

The Day Skipper Theory course typically involves 40–45 hours of tuition, which can be delivered over five full days, several weekends, or online at your own pace. Many centres include three additional hours for assessment. The flexible format means it can fit around work or family commitments.

The RYA Day Skipper Theory course is assessed through continuous learning and a final written exam. Throughout the course, you'll complete exercises in navigation, tidal calculations, collision regulations, and passage planning. Instructors provide feedback as you go, ensuring you’re ready for the exam. The final test typically includes chartwork, tide questions, and scenario-based planning. There’s no practical element in this course, but it’s an essential foundation for the RYA Day Skipper Practical course. On completion, you’ll receive the RYA Day Skipper Theory certificate, which is widely recognised and often required by charter companies. You can book this course at one of adventuro’s many RYA-approved centres around the UK.
