A $40 service of your life-jacket could save your life, Tasmanian marine authorities say.
A new Marine and Safety Tasmania television advertisement highlights the importance of having a life jacket that has been serviced.
Police have also warned they will be out in force this summer to ensure boats are safe.
In the advertisements, to screen tonight, Andrew Hart from the television series Hook, Line and Sinker is shown in the water with a properly inflated life jacket and then with a life jacket that did not work.
"I was only in the water for a few minutes for both shots - my breath was literally taken away both times," Mr Hart said.
"But at least with the life jacket properly inflated I could stay afloat. I don't know how long I would have lasted when I was wearing the one that didn't work."MAST chief executive Lia Morris said two recent Coroner's reports demonstrated the need to continue to focus on the importance of safety equipment and life jacket wearing and readiness.
"Tragically, these fatalities highlight the importance of wearing a life jacket, ensuring the inflatable life jacket is serviced and understanding how it works" Ms Morris said.
"MAST has the data to show that some 94 per of Tasmanians wear their life jackets - but have they been serviced?
"We want Tasmanian boaties to get their inflatable life jackets serviced.
"Is your life worth a $40 service? If something goes wrong at on the water, will your life jacket work?"
Ms Morris said another focus of the advertising campaign was on a safety checklist.
"Is your safety gear within reach? Have you checked the weather? Have you told someone where you are going?"
Police have also urged Tasmanians to ensure their boats and safety equipment is in proper working order as summer approaches.
Sergeant Damian Bidgood from Marine and Rescue Services said statistics showed that most boating incidents occur during holidays.
"We want people to enjoy their time on the water, but we want them to make it home safely," Sergeant Bidgood said.
"It's vital that boats and safety equipment are in good condition and have been serviced regularly.
"Equipment such as life jackets, flares, and emergency beacons should be stored on board in a place that's easily accessible if needed in an emergency."
