Daisy Turner, her son George, aged 10, his eight-year-old sister Violet and cousin Olivia Oughton, 13, took the plunge on 19 May and finished their 67,000-metre Channel challenge on 25 July.
Instead of braving the busy Straits of Dover, they clocked up the equivalent of swimming from Dover to Calais and back at local pools over several visits.
They were joined by Daisy's mum Julie Oughton, while her dad Roger acted as support crew and friends Trevor and Lesley Parfitt also helped the cause by swimming vital extra lengths.
On Sunday, 24 August the family came to see the crew at Hunstanton RNLI and presented them with the £90 they'd raised by asking friends to give donations.
Daisy said the family decided on the dip because they knew about the work of the RNLI from friends who volunteered at the station, including Trevor and Lesley's daughter Charlie, who's a hovercraft commander and souvenir shop team member Pru Fox.
'We think it's amazing that you're all volunteers and it's nice to support the local RNLI service and see the practise on a Sunday morning,' she said.
'The children like to support the lifeboat because they know if anyone's in trouble it will be there to help and donations are so important to help keep it running.'
Lifeboat operations manager Mike Gould said the crew's work would not be possible without the kindness of supporters.
He added it was always moving when young people raised money for the charity.
Editor's Notes
Hunstanton lifeboat station operates the fast inshore lifeboat Spirit of West Norfolk and the search and rescue hovercraft
Hunstanton Flyer.
Like more than 200 RNLI crews around the coast of the UK and Ireland, their lifesaving work would not be possible without the kindness of those who donate to the charity that saves lives at sea.
