James and Belinda Richardson, from London, are set to clock up 3,500 miles as they raise funds for the charity that saves lives at sea.
Their aim is to raise £89,000 to buy a D class inshore lifeboat by 2024.
And they're well on their way to pushing the boat out, with £70,000 already in the bank.
'We started these RNLI fundraising tours back in 2018 when we visited all 238 RNLI stations in the UK and Ireland,' said Belinda.
'In successive years we have toured RNLI stations around Scotland, Wales, Northern Ireland and Ireland. In 2023 it is England and the Isles that we are focusing on.'
As their distinctive car pulled up outside the Hunstanton station, on Sea Lane, Belinda said she remembered it from a previous visit on their 2018 tour.
'We went upstairs, there's a desk at the window and what a view,' she said. 'I'd never get any work done if I was looking at that.'
When the Richardsons visited on Friday, 1 September, you could see their next stop Skegness across The Wash from the station ops room.
While it might have looked close, the couple faced a 70-mile trip by road around the estuary to reach it.
The Richardsons, who live in London, originally planned to tour Europe after they retired from building and interior design.
But their plans changed after they watched the TV series Saving Lives at Sea, which highlights the heroism of the RNLI's volunteers who maintain a 24/7 search and rescue watch around the coastline, 365 days a year.
'We could see a way to tour and at the same time raise money for a charity we both love,' said Belinda.
'James and I, as members of the public, are in awe of what the RNLI does.'
Crew members and volunteers were in awe of the car, a Porsche 911 in the RNLI's trademark orange, covered in branding for the charity and sponsors who have backed the trip.
Paul Stewart, one of the station's deputy launch authorities, said: 'They're doing a great job and I really admire what they're doing, trying to get to every station. It was really good to see them.'
Paul was presented with a plaque by Matthew Lockwood, centre principal at Porsche Centre Norwich, which sponsored the visit.
After Skegness, the Richardsons planned to continue north up the East Coast on their anti-clockwise circuit of the coast.
Their journey, which began at St Helier, on Jersey, on 23 August, is expected to end at the RNLI's HQ at Poole on Friday, 15 September.
Notes to editors
D class lifeboats are rigid, inflatable craft which are involved in 60 percent of the RNLI's rescues.
The 25-knot vessels are known as the charity's 'pocket rockets' by their crews, who can carry out rescues in shallow waters larger all-weather lifeboats can't reach, along with surf, close to rocks and even caves.
In over 50 years of service, they have saved thousands of lives.
Since Hunstanton's current station opened in 1979, its inshore lifeboat Spirit of West Norfolk and her predecessors have helped save 140 lives and render assistance to more than 600 people who found themselves in difficulty or in danger.
In 2003, she was joined by the hovercraft Hunstanton Flyer, which has since then been launched 250 times, saved 13 lives and assisted a further 150 people.
