The RYA Coastal Skipper Yachtmaster Offshore is an advanced course that follows on from the RYA Day Skipper Theory and will develop further knowledge and skills on navigation, pilotage, collision regulations and meteorology. 

It is for sailors and motor boaters who are looking at embarking on difficult passages, for example, offshore and/or at night. This course is also a must for anyone wishing to take a RYA Coastal Skipper or Yachtmaster Offshore practical exam.

Our evening classes, which take place in our waterside classroom, start in the Autumn and are great for those who live within easy travelling distance of our school in Ipswich, Suffolk and want to fit learning into busy lifestyles and around work and family commitments.
