Fifty people returned home to their families after being rescued by lifeboat crews off the North Wales Coast last year.
The RNLI said they were launched in North Wales 536 times in 2016, which represented a 15 per cent increase in launches compared with the previous year.
Flint RNLI was launched 13 times in 2016, with two people being rescued.
One of those rescues was deemed to be a “lifesaving” rescue.
Matt Crofts, RNLI Lifesaving Manager said: “Prevention is key for the RNLI – helping people by providing communities with the skills and knowledge to help keep themselves safe when they visit the coast.
“Our annual Respect the Water drowning prevention campaign will be launching again soon and we urge people to give water the healthy respect it deserves.
“While we will always answer the call for help, myself and everyone within the RNLI would like to see people thinking more about their safety whilst at the coast.”
As well as the number of lifeboat launches being up, the volunteer crews rescued 562 people in trouble on the coast – 27 per cent more than in 2015.
The busiest North Wales station was Rhyl RNLI as the crews responded to 66 call-outs over the course of the year, rescuing 50 people and saving two lives.
Mr Crofts added: “We’re calling on anyone visiting the coast to make safety a priority; whether that means wearing a lifejacket, checking their vessel before they go afloat, knowing they should call 999 and ask for the Coastguard in the event of an emergency, checking the tide times before they set out, or staying away from cliff edges and unstable coastal paths.”
The reason for the callouts varied from machinery failure, searching for missing people, rescuing those in danger of drowning and rescuing people cut off by the tide.
One incident dealt with in North Wales last year saw the tragic death of two teenage boys from Birmingham.
Today, a partnership between the RNLI and Birmingham City Council will be launched, with youngsters in the city being given water safety training.
