Oliver – UKSA General Ship Knowledge (OOW Yachts) student

“I recently attended both the GSK and Nav Radar course online with Ross. I thought the course was very well run and a great effort was made to accommodate the restrictions made with it not being in person. Ross was very helpful, and made himself available in the evenings and at the weekend if help was required.”
