RYA Diesel Engine Maintenance Course

Get up close and personal with diesel engines and learn to maintain and repair common problems at sea. A highly recommended course for yacht owners, and Coastal Skipper and Yachtmaster candidates.

You will also be able to undertake routine servicing and maintenance tasks.This course is very hands on – you will spend some time on theory, some time working on a training engine in the class room and some hours “getting down and dirty” on an engine aboard a yacht. No previous experience required!
