With an increase in new boat and jet ski owners in the past few years, Water Safety Bay of Plenty is encouraging vessel owners to enrol in Coastguard Boating Education courses.
"Improving your knowledge is never a bad investment," regional water safety strategy manager Dave White said.
"CBE run some fantastic courses and they're all available online so you can do them when it suits you."
The Day Skipper course is the most popular and it's suitable for a range of vessels, teaching skippers everything from handling techniques and navigation, to regulations and knots.
"We highly recommend the Day Skipper course to all jet ski and vessel owners," White said.
