This five-day course covers celestial navigation, passage planning, worldwide meteorology, and use of navigational instruments, preparing participants for the RYA Yachtmaster Ocean practical exam or enhancing long-distance offshore sailing skills. Key Details Duration: 5 days Group Size: 1–6 participants Minimum Age: 17 years Location: Menai Bridge, Isle of Anglesey, LL59 5EF Key Skills Advanced celestial navigation using a sextant Comprehensive ocean passage planning Interpretation of global weather systems Use and care of navigational instruments Risk assessment and voyage decision-making What to Expect The course begins with a focus on celestial navigation, teaching participants to take meridian altitudes and other celestial sights using a sextant. Exercises and calculations reinforce theoretical understanding and build confidence in navigation beyond land-based references. As the programme continues, participants learn comprehensive ocean passage planning, including route plotting, estimating fuel and provisions, assessing tides and currents, and applying worldwide meteorological data. Scenario-based exercises simulate real ocean voyages, developing decision-making and risk assessment skills. The final stage integrates all learned skills, with case studies and simulated passages to apply navigation, planning, and meteorology knowledge in practical scenarios. Instructors provide detailed feedback, ensuring participants are fully prepared for theoretical and practical offshore sailing challenges. Location The course is held at our RYA-accredited training centre in Menai Bridge, Isle of Anglesey. This location provides access to tidal waters and coastal features that enrich learning through real-world examples of navigational hazards and tidal streams. Our classrooms are modern and well-equipped, supporting intensive study while incorporating the local marine environment into lessons. Instructors use Menai Bridge and the surrounding North Wales coast to illustrate how advanced ocean navigation principles apply in practical contexts. Prerequisites Participants must have completed the RYA Yachtmaster Offshore Theory course or hold equivalent knowledge. This foundation allows full engagement with the advanced concepts of celestial navigation and ocean passage planning.

This course is aimed at sailors who have completed the RYA Yachtmaster Offshore Theory course or possess equivalent knowledge. It is ideal for those preparing for the RYA Yachtmaster Ocean practical exam, or anyone wishing to gain the skills and confidence required for long-distance ocean sailing. Participants benefit from a structured, intensive programme that builds their understanding of advanced navigation, celestial techniques, passage planning, and worldwide meteorology. It is suitable for both experienced offshore sailors and those transitioning from coastal sailing who want to develop a thorough understanding of ocean navigation principles. ### Do I need prior ocean sailing experience to enrol? No prior ocean sailing experience is required, as the course focuses on shore-based theoretical knowledge. The emphasis is on developing an understanding of celestial navigation, passage planning, meteorology, and risk assessment, rather than hands-on offshore sailing. However, participants must have a solid grounding in basic navigation, such as that covered in the RYA Yachtmaster Offshore Theory course. A keen interest in long-distance sailing and the willingness to study advanced navigational topics is essential for getting the most from the course. ### What topics are covered in the course? The course covers advanced celestial navigation, including use of a sextant, meridian altitudes, intercept methods, and calculating positions at sea. It also focuses on ocean passage planning, taking into account tidal streams, currents, fuel and provisioning, and voyage risk assessment. Meteorology is a key component, teaching participants how to interpret global weather patterns, synoptic charts, and forecast data to plan safe and efficient ocean passages. Other topics include the use of navigational instruments, long-distance passage management, and collision regulations applicable in offshore waters. ### How is the course delivered? The course is delivered through classroom-based sessions, combining lectures, exercises, and scenario-based discussions. Case studies simulate realistic long-distance passages, requiring participants to apply skills in planning, navigation, and decision-making under varied conditions. Online learning options may also be available through RYA Recognised Training Centres, allowing participants to study theory at their own pace while still benefiting from instructor support. Whether classroom-based or online, the course emphasises understanding rather than memorisation. ### Are there examinations associated with the course? Yes, an assessment is conducted at the end of the course to evaluate understanding of celestial navigation, passage planning, and meteorology. Successful completion is required to obtain the RYA Ocean Yachtmaster Theory certificate. The assessment includes both written and practical elements, requiring participants to demonstrate accurate plotting, tidal calculations, and risk evaluation. This ensures that candidates have the knowledge and skills needed for the Ocean Yachtmaster practical exam and safe long-distance offshore navigation. ### What materials are provided during the course? Participants are provided with comprehensive course materials, including textbooks, charts, plotting sheets, and access to online resources. These are used for exercises and as reference material for future voyages. Charts and navigational aids are supplied for all classroom and scenario exercises. Participants may choose to bring personal calculators or plotting tools, but all essential instruments and publications are included in the course package. ### Is there a minimum age requirement for the course? The minimum age to enrol is 17 years, reflecting the maturity required to study advanced navigation theory and manage complex offshore passage planning. Participants must also be capable of committing to focused study over several days. The age requirement ensures that participants are ready to understand and apply navigational and meteorological principles, develop critical decision-making skills, and prepare for the responsibility of managing ocean passages safely. ## Media - **Primary image URL (resolved in app; may be absolute)**: https://adventuro.com/cdn-cgi/image/width=1200,format=auto,quality=90/https://wp.adventuro.com/wp-content/uploads/2025/09/Screenshot-2025-09-16-131823-2.png - **Gallery image count**: 8 ## Limitations - Availability, exact session times, and final price may depend on the live booking flow. - This Markdown is generated from the same catalog fields as the public HTML page at the canonical URL above.
