Local boaties are being given safety messages on the water in a hope this summer will be fatality-free.
Rotorua Lakes Coastguard president Barry Grouby said the volunteer organisation spent the long weekend on Lake Tarawera and Lake Rotoiti promoting its VHF channel 81.
"A lot of people were from out-of-town and didn't know what the channel was out there to get help," Mr Grouby said.
"A lot of Rotorua people that we saw didn't have a radio, they think because they're on a lake they didn't need one but things can change quickly in seconds. They wouldn't know what to do, who to call.
"We are saying this channel is a faster avenue to get help. It is monitored 24/7. People can ring 111 who will contact the Coastguard but with channel 81 you are missing out a whole lot of middle people."
