A total of 193 competitors took part in what was billed as the first national Wales Open Stone Skimming Championship.
Sunday's event at Castle Pond attracted competitors of all ages
People of all ages turned up to bounce stones along specially-built lanes at Castle Pond in Pembroke, with prizes for those who skimmed the furthest.
Run under rules used in the world championships, Countryside Council for Wales employee Mike Camplin won with a throw of 75 metres.
Organisers had transported 2,000 small quarry stones ready for the event.
The contest was staged by Manorbier Cricket Club and was the idea of Mark Davies, who said: "I've been chucking stones into the sea all my life having grown up in Pembrokeshire.
"I came across the World Stone Skimming Championships in Scotland a few years ago so I went up to take part and thought it would be a good idea to have one in Wales."
STONE SKIMMING RULES
Stones, no more than 3 inches in diameter, are skimmed for greatest distance
Each must make at least three bounces in the water
Entrants can have up to five skims of the stones which are supplied by the organisers
A "launch platform" was built on the side of the water and lanes marked with buoys laid out.
"It's not done on the number of bounces, it's done on distance, but the stone must bounce three times and remain in the lane," added Mr Davies.
A large crowd gathered to take part and watch, with the contest divided into categories of men, women and juniors.
Mr Davies said one of the problems was finding enough stones.
"We got over 2,000 from stone quarries in north Pembrokeshire and put them in a cement mixer to round off the edges and make them flat," he added.
"We had 193 people who threw - mainly families where dads, mums and children had a go.
"It was a good event and I think people enjoyed it.
"The venue, right under Pembroke Castle, was an excellent place where people could view from three sides of the water."
