The harbour at Porthleven was turned into a giant swimming pool last weekend to celebrate the mending of the sea defences.
Before the boats which were removed during winter storms were craned back into the harbour, locals Richard and Sarah Smith organised a lido day, with fun events both in and out of the water.
There were areas for paddling and swimming, as well as lilo races and a mini triathlon.
There was also the reinstatement of an old sculling race organised by Andrew Bayley and harbourmaster Phil Ward.
Sarah said she was “absolutely astounded” by the turnout.
She said: “We didn’t realise how many people would come on a cold March afternoon, and they hung around rather than just coming for a little bit.
“There were young and old, people who remembered the celebrations in the past with swimming races in the harbour, and the surfer lot as well.”
She thanked the harbour owners for allowing them to use the harbour free of charge, Tony Woodhams for electricity, Caitlin Mclintock for making the posters, and Suzanne Williams for donating the prizes.
She also thanked Out of the Blue for donating two barrels of beer, crates of wine and soft drinks, which were all sold to raise around £700 for the Fishermen’s Mission.
After organising the event in just short of three weeks, Sarah said it was so successful they may make it an annual event, and are hoping to combine it with the fishermen’s barbecue in August, “when it’s warmer.”
