It is a comprehensive shore-based course covering everything from position fixing to interpreting weather forecasts, giving you the confidence to plan and navigate extended coastal and offshore passages. 🧭 Key Details Learning: Shore-based, in the classroom, online or by distance learning Meeting point for classroom: 40 High Street, Menai Bridge, Anglesey, LL59 5EF Start point: Knowledge to the level of RYA Day Skipper Theory Certificate: RYA Yachtmaster Offshore Theory, also called Coastal Skipper/Yachtmaster Offshore Theory What it enables: The theory you need before Yachtmaster Coastal or Offshore practical exams 🔑 Key Skills Position fixing and course shaping and plotting Tidal streams, tidal heights and their effect on passage planning Almanacs, Admiralty publications and electronic navigation Taking and interpreting weather forecasts Plotting weather systems and using a barometer 👁️ What to Expect Shore-based learning covers position fixing, using a range of techniques to establish an accurate position at sea, and course shaping and plotting, planning and plotting a course while taking into account tide, leeway and other factors. Tidal knowledge covers tidal streams, tidal heights and their effect on passage planning. You also use almanacs and Admiralty publications for planning and navigation, and electronic position finding equipment as part of modern navigation. Meteorology takes you through taking and interpreting weather forecasts, plotting weather systems and making weather predictions using a barometer. This course is a prerequisite for anyone wishing to go on to complete an RYA Yachtmaster qualification, and is suitable for those looking to build the theory knowledge needed to skipper confidently on longer, more challenging passages by sail or power. 📍 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 and distance learning use the same shore-based syllabus, so you can take the course 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 on… ### Essential information _None._ ### What’s included RYA Yachtmaster Offshore Theory tuition, classroom, online or by distance learning Course materials for the shore-based syllabus 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 ### What is Yachtmaster Offshore Theory? The aim of the RYA Yachtmaster Offshore Theory course, also known as RYA Coastal Skipper/Yachtmaster Offshore Theory, is to take your navigation and meteorology knowledge to the standard required for the RYA Yachtmaster Coastal and Offshore practical exams. It is a comprehensive shore-based course covering everything from position fixing to interpreting weather forecasts, giving you the confidence to plan and navigate extended coastal and offshore passages. ### What previous knowledge do I need? Participants should have knowledge to the level of the RYA Day Skipper Theory course. That is the base the Yachtmaster paper builds on, so chartwork, tides and collision regulations should already feel familiar. There is no minimum age requirement on the RYA syllabus. If your Day Skipper Theory is a few years old, revise the basics before you start so the week can stay at this standard. ### How can I take the course? This is a shore-based course that can be taken in the classroom, online or by distance learning. The syllabus is the same on each route, including position fixing, course shaping, tides, publications, electronic navigation and meteorology. Classroom days are at 40 High Street, Menai Bridge. Online and distance learning let you work through the same exercises away from the classroom. ### What topics are covered? You cover position fixing using a range of techniques, course shaping and plotting while taking into account tide, leeway and other factors, and tidal streams and heights and their effect on passage planning. You also use almanacs and Admiralty publications, electronic position finding equipment, and meteorology: taking and interpreting weather forecasts, plotting weather systems and making weather predictions using a barometer. ### What does the course enable me to do? This course is a prerequisite for anyone wishing to go on to complete an RYA Yachtmaster qualification. It is suitable for those looking to build the theory knowledge needed to skipper confidently on longer, more challenging passages by sail or power. Passing does not replace the practical exam. It is the shore-based standard the Coastal and Offshore examiners expect you to have before you take a boat on those passages. ### 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 tidal examples on the chart are the same Menai Strait streams you will meet when you go afloat. ### Is this only for sailors? No. The course is suitable for those looking to build the theory knowledge needed to skipper confidently on longer, more challenging passages by sail or power. The chartwork, tides and meteorology are the same whether the boat has a keel or an outboard. Seawake is a powerboat school, so the classroom examples often sit on the North Wales coast and the Strait, but the RYA paper is the Yachtmaster Offshore Theory syllabus for both. ### Is there an exam? Yes. The shore-based course ends with the RYA Yachtmaster Offshore Theory exam, which checks the position fixing, course shaping, tides, publications and meteorology you have been working through. Passing confirms you have the theory required for the Yachtmaster Coastal and Offshore practical exams. It does not itself qualify you as a Yachtmaster. ### What should I bring to classroom days? A notebook and pen are enough. Course materials, charts and publications are provided. Wear comfortable clothing for a full day at the chart table. Bring lunch or money to buy it locally. The classroom is in Menai Bridge town, with shops a short walk from 40 High Street. ### How does this sit with Day Skipper Theory? Day Skipper Theory is the comprehensive introduction to chartwork, navigation, meteorology and seamanship. Yachtmaster Offshore Theory takes that knowledge to the standard required for the Coastal and Offshore practical exams. If you do not yet have knowledge to Day Skipper Theory level, start there. This course assumes that base so it can spend the hours on course shaping, publications and weather at Yachtmaster pace. ## 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/2025/09/001-scaled.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.
