Mechanical failure is the main cause of rescue boat callouts to yachts. The day includes basic maintenance and engine care, which will prevent most cases of engine failure.

The aim of the course is to give you an awareness of the main systems of a marine diesel engine and the ability to take simple measures to prevent mechanical breakdown at sea and rectify defects which do not require workshop support.

An incredible adventure! The experienced owners Carly & Jamie of SCY were fantastic in booking & organising, the instructor was incredibly knowledgeable & professional, and the boat was amazing. Can’t rate Southern Cross Yachting highly enough- I’m already planning my next lesson

We were lucky enough to spend a day with Jamie on Moreton bay and can’t speak highly enough about it. Three of us with varied previous experience of sailing joined with a father and son to share in a day of learning the ropes. The day was tailored to our varied needs and at all times we were able to ask questions and glean experience from Jamie’s wealth of knowledge. We would highly recommend signing up for a course if you’re interested in getting back on the water after a hiatus. Thanks so much guys! It was a priceless day!
