This RYA Ocean Yachtmaster Theory course covers celestial navigation, passage planning, worldwide meteorology and the use of navigational instruments, preparing you for the RYA Yachtmaster Ocean practical exam or for longer offshore passages by sail or power. 🌊 Key Details Duration: Typically 5 days in the classroom, with online study available Meeting point for classroom: 40 High Street, Menai Bridge, Anglesey, LL59 5EF Minimum age: 17 years Start point: RYA Yachtmaster Offshore Theory, or equivalent knowledge Certificate: RYA Ocean Yachtmaster Theory 🔑 Key Skills Celestial navigation, including use of a sextant Ocean passage planning and voyage decision-making Interpretation of worldwide weather systems Use and care of navigational instruments Risk assessment on a long-distance passage 👁️ What to Expect The course begins with celestial navigation, taking meridian altitudes and other sights using a sextant, then working the sights so you can fix a position when there is no land in sight. You then move on to ocean passage planning: route plotting, tides and currents, fuel and provisions, and the meteorology that sits with a long passage. Worldwide weather, synoptic charts and forecast data are used to decide when to go and when to wait. Scenario exercises pull the navigation, planning and weather together so you can see how the pieces sit on a real ocean voyage. The course is shore-based, in the Menai Bridge classroom or online, and ends with an assessment of the theory. 📍 Location Classroom days are held at our training centre in Menai Bridge on the Isle of Anglesey, with a fully equipped classroom in the town itself. Online study uses the same syllabus, so you can complete the theory in the way that suits you. They say if you can navigate the Menai Strait then it sets you in good stead for any navigational boating challenge. The classroom is easily reached by taking junction 8A onto the A5 off the A55 at Britannia Bridge, with Pay and Display parking across the road. ✅ Prerequisites You should have completed the RYA Yachtmaster Offshore Theory course, or hold equivalent knowledge. That is the base this course builds on, so chartwork, tides and coastal meteorology should already feel familiar before you pick up a sextant. No previous ocean miles are required. A genuine interest in long-distance passages and a willingness to work through celestial calculations and weath… ### Essential information _None._ ### What’s included RYA Ocean Yachtmaster Theory tuition, classroom or online Course materials, charts and plotting sheets Exam entry Tea, coffee and light refreshments on classroom days ### What’s not included Transport to and from the meeting point Lunch on classroom days, which you can bring or buy locally Parking at the public Pay and Display car park in Menai Bridge ### Kit list A notebook and pen Comfortable clothing for classroom days Lunch, or money to buy it locally, if you attend in Menai Bridge ## FAQs ### Who is Ocean Yachtmaster Theory for? This course is for anyone who has completed RYA Yachtmaster Offshore Theory, or holds equivalent knowledge, and wants the celestial navigation and ocean passage planning needed for the Yachtmaster Ocean practical exam or for longer offshore passages. It is shore-based theory, so it suits both sailors and powerboaters who want to plan a passage when there is no land in sight, not only those who already have ocean miles. ### Do I need ocean sailing experience? No previous ocean miles are required. The course is shore-based and concentrates on celestial navigation, passage planning, worldwide meteorology and the use of navigational instruments. You do need Yachtmaster Offshore Theory, or the same knowledge, so the week can stay on sextant sights and ocean weather rather than revisiting coastal chartwork. ### What will I study? You will take meridian altitudes and other celestial sights using a sextant, work the sights to a position, and plan ocean passages with tides, currents, fuel, provisions and worldwide weather in mind. Meteorology covers global weather systems, synoptic charts and forecast data. You also cover the use and care of navigational instruments and the risk assessment that sits with a long-distance voyage. ### How is the course delivered? The course is shore-based. You can take it in the classroom at 40 High Street, Menai Bridge, typically over five days, or study the same syllabus online. Classroom days combine chart-table exercises, sight reduction and weather plots. Online study uses the same RYA Ocean theory, with the assessment at the end. ### Is there an exam? Yes. The course ends with an assessment of celestial navigation, passage planning and meteorology. Passing gives you the RYA Ocean Yachtmaster Theory certificate. That certificate is the shore-based standard the Ocean practical exam expects. It does not itself make you a Yachtmaster Ocean. ### What is the minimum age? The minimum age on this listing is 17. That sits with the maturity needed for celestial calculations and for planning a passage that may last many days. You also need Yachtmaster Offshore Theory, or equivalent knowledge, before you start, so the age is only part of the picture. ### What materials are provided? Course materials, charts and plotting sheets are provided for the classroom and for the exercises. You do not need to bring your own sextant, though you may if you already own one and want to use it. A notebook and pen are enough for classroom days. Online learners work through the same publications in digital or posted form. ### Where are the classroom days held? Classroom days are at our training centre in Menai Bridge on the Isle of Anglesey. The classroom is in the town itself at 40 High Street, LL59 5EF, with Pay and Display parking across the road. Take junction 8A onto the A5 off the A55 at Britannia Bridge. The same classroom is used for Day Skipper and Yachtmaster Offshore Theory. ### How does this sit with Yachtmaster Offshore Theory? Yachtmaster Offshore Theory takes your navigation and meteorology to Coastal and Offshore exam standard. Ocean Theory is the next shore-based step, adding celestial navigation and worldwide weather for passages out of sight of land. If you do not yet have Offshore Theory, start there. This course assumes that base so the hours can stay on the sextant and the ocean plot. ### Is this only for sailors? No. The theory is the same whether the boat has a keel or an engine. Seawake is a powerboat school, and the classroom examples often sit on the North Wales coast, but the RYA paper is Ocean Yachtmaster Theory for sail or power. If you skipper a motor yacht or a RIB on longer passages, the celestial work and the weather plots are still the tools you need when GPS is not the only answer you want. ## 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/DJI_20250411115506_0040_D.webp - **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.
