  • Thought it was a very good course – I think online works well for this and I have learnt a lot from it. It’s also jolted me to do a few things, like get a permanent radar reflector fitted and check fire extinguishers etc. so of practical value also. Peter – May 2016
  • Impressive course for such a last minute booking. Most impressive was the fact that id had no experience before this and that was tailored into the course as much as possible. The online course is excellent, teaching you in some areas even deeper knowledge than is needed. Mark is an excellent and very patient instructor who took in to account all of the various students experiences and focused on each individual’s areas for improvement.  Edward, October 2014 ( Also took practical Day Skipper course)
  • Rapid and clear tutor feedback. Willing to respond to specific queries – unlike other similar tutors I have experienced
  • Quick response to exercise submissions.
  • Easy to follow. The animations were very helpful in building understanding.
  • Almost instant e-mail feedback. Always available at the end of the phone if I rang to ask questions.
  • The combination of online “own pace” learning combined with easy access to tutorial support when needed makes the course. ideal for anyone that cannot commit to regular college nights.
  • very happy with the course and especially all those those at Commodore, Stuart and his team were very helpful and accommodating. I would definately recommend others to do this course. I have already put what I have learnt to practice – it works! Thanks
