The number of people who died along Britain's coast in 2013 was the highest in four years, the RNLI said as it launches a campaign calling on people to Respect the Water.
Figures show that 167 people died in water-related accidents and a further 368 were rescued by lifeguard crews after getting into difficulties.
Cold water shock, rip currents and fatigue were common factors in contributing to accidents at the coast while alcohol played a part in 28 deaths last year.
As the temperature continues to soar RNLI coastal safety manager Ross Macleod called for people to stay safe around the water.
"We really feel that that number is too high and we need to do something about it," he said.
The campaign will be launched in Brighton today by England rugby player James Haskell who said: "This is about being smart and safe when you are there."
Respect the water-that's the message from the RNLI. The charity is launching a campaign today warning people to be extra careful this summer. It comes after new figures revealed 32 people lost their lives on the south west coast last year.
A couple from Somerset, whose son took his own life as a student, are hoping to save dozens of lives in his name.
Chris and Debbie Rundle from Williton were determined to turn their son Toby's death into something positive.
They raised more than a £170,000 towards the cost of a new lifeboat, which took to the waters off Clovelly in North Devon for the first time this weekend.
Richard Lawrence reports:
The newly named Atlantic class inshore lifeboat Toby Rundle took to the water of Clovelly on Saturday.
The lifeboat has been funded by a fundraising appeal started four years ago by the family and friends of Somerset student Toby Rundle.
More than £174,000 was raised towards the cost of the lifeboat in memory of Toby who died in 2009 as he was starting his third and final year of studies at Oxford University. He was the only son of journalists Chris and Debbie Rundle.
Crewed by RNLI volunteers, the Toby Rundle went into service officially on 6 May and on Saturday Philippa Rundle, Toby’s sister, officially named her in front of over a hundred of his close family and friends.
A lifeboat was officially named in Clovelly today in memory of a young student.
The 'Toby Rundle' went into service at the beginning of May, after friends and family raised nearly 2 hundred thousand pounds towards the cost. Today the boat was officially named by Toby's sister.
The RNLI has released dramatic footage of the moment Teignmouth lifeboat crew stopped an out-of-control speedboat and rescued a man.
The man fell aboard from his speedboat earlier this month, knocking the throttle and putting the boat into a spin. The volunteer crew raced to the scene and managed to stop it. The man, who was wearing a lifejacket, was rescued and taken to hospital as a precaution.
The pictures, courtesy of the RNLI, show the moment the crew lasso the boat and manage to switch off its endless spiral.
Ilfracombe RNLI has saved two men cut off by the tide near Lee Bay in North Devon.
The men had been walking from Woody Bay to Lee Abbey as the tide was coming in. When they realised they were being cut off, they tried swimming but gave up and came ashore at Crock Point.
Coastguard teams began a cliff descent but it was decided to send in a member of the lifeboat crew, which was standing by. One of the team helped the pair on board the inshore lifeboat, which took them to Lee Bay where they were handed over to representatives from Lee Abbey.
Volunteer helmsman, Duncan Thomson says it is crucial that coastal walkers check the tide times.
It is important to remember that the Bristol Channel has one of the largest tidal ranges in the world, and a result of this is that many of the beaches and pathways that are available to walk on during low tide become completely covered as the tide comes in. If you intend to walk along the coast, please do check the state of the tide, and be aware that somewhere you were able to walk earlier in the day may not be available to you upon your return.
A man has had a lucky escape after being thrown from his speedboat in Teignmouth Quay, Devon, yesterday (Friday 16 May). He had been hurled into the water from his speedboat. The boat was then going round in circles and the man was trying to swim away to safety.
The Coastguard rescue team and RNLI inshore lifeboat were sent to the scene. The lifeboat crew managed to bring the boat under control by cutting the engine.
The man had been picked up by another boat nearby and was brought ashore where he was met by Coastguard Rescue Officers. He’s since been taken to hospital to be checked over, but doesn’t appear to have been badly hurt.
It appears the man took off his kill cord as it was too short to allow him to tie up his boat. Unfortunately, he accidentally knocked the throttle, the boat jerked forward and he fell into the water. Without the kill cord, the boat’s engine didn’t cut out and then locked into driving round and round in circles. Luckily he did have a lifejacket on and was able to quickly swim away to safety and the boat was soon brought under control. We always recommend people wear their kill cord at all times when on the boat. Make sure it’s a suitable length so you can move around your vessel.
A couple rescued from their yacht in stormy seas off the Cornish coast say they only survived thanks to the bravery of lifeboat crews. The dramatic rescue off the Lizard was captured on camera by the RNLI. Steve Hardy has this exclusive report.
A lifeboat station in Devon welcomed a new arrival today - which will be able to respond to emergencies faster than ever before.
Exmouth is the first town in the South West to receive the Shannon Class lifeboat. Ilfracombe and St Ives are expected to receive their new boats next year. John Andrews watched it in action.
