The couple are both keen sailors with Looe Sailing Club and joined Looe RNLI as crew at around the same time.
Amber’s father, Clive Palfrey, Looe RNLI’s lifeboat operations manager, said how “proud” he was to see the crew marching down to form the arch and pull off the surprise – adding it was “an amazing Father’s Day weekend”.
Ian Foster, from the lifeboat station, said the crew were “delighted” to be a small part of the wedding.
He said: “Yellow wellies are synonymous with the RNLI, the iconic yellow welly forms part of the crew’s safety equipment both for our shore crew and boat crew with their drysuits.”
He said the yellow welly symbolised bravery, safety, and the charity’s mission at sea.
