Johnathon Jarvis walked the 60 or so miles from the RNLI's Happisburgh lifeboat station in north Norfolk to its base along the coast at Hunstanton in late May.
The four-day walk accompanied by parents Lee and Kayleigh was his second trek for the lifesaving charity, after a 40-mile walk from his home near Downham Market to Hunstanton raised £3,150 last year.
On Sunday, 10 August, he visited the Hunstanton crew to present a cheque for £4,337.
He joined a session of Storm Force, the station's popular kids' club, led by the station's visits and water safety lead Kate Craven.
'The running total Johnathon's raised for the RNLI so far is something like £7.907,' said Kate.
'We're a charity, we save lives at sea and we couldn't do what we do without people like him.'
Johnathon then headed for the beach, where hovercraft Hunstanton Flyer was returning from a training sortie.
'He's a unique individual who puts others before himself,' said dad Lee as the craft made its way inshore.
'He just got on with the walk and loved every mile of it.'
Hovercraft commander Jon Butler, pilot Andrew Craven and crew member Stu Murray welcomed him aboard for a catch-up.
'Johnathon's been supporting us for a number of years now,' said Jon.
'He's a real inspiration both to our crew and to other young people.'
Johnathon said: 'If the RNLI didn't have people raising money, how would they be able to save people - it would be impossible.'
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.
