"Thank you for an informative and fun day on the RYA2 powerboat refresher course. Throughout the day you built on my confidence and skill levels in an intuitive and fun way, going the extra distance to re-mediate my charts skills in your own time. I now feel I have the confidence and skills to enable me to skipper a busy dive boat." 

"Guy was a very knowledgeable instructor with a friendly, professional approach. I enjoyed the course and met some really nice people and also had a laugh. I would recommend his instruction methods to a wide selection of people in many walks of life."
