A man was left clinging on to a ladder in the harbour at Staithes having suffered a broken leg and a gashed head when he got washed off the pier by high tides.
He was getting battered by repeated waves and Sean Baxter, the deputy launch, tried to drag him out of the water but couldn’t so he had to scramble the Staithes and Runswick lifeboat.
Conditions were said to be “tricky” for the lifeboat which, crewed by helm Lee Jackson, managed to get alongside the casualty and pluck him to safety.
However, it couldn’t land up the slip way and had to transport the casualty, in his 30s, up Roxby Beck to an ambulance.
A second casualty who also ended up in the water managed to clamber out and make it back to the safety of the pier themselves.
The RAF Sea King rescue helicopter was drafted in from its base at Leconfield to airlift the pair to James Cook Hospital for treatment.
But, due to the number of onlookers and bystanders on the beach at Staithes, it was unable to land near the lifeboat station.
The casualties were taken by ambulance to Cowbar where it was re-directed for landing.
The incident happened at around noon on Tuesday and the lifeboat and coastguard have since issued a warning to people to be aware of sea conditions and tide times.
They said: “Our message is simple, but is often forgotten.
“If venturing out to enjoy our coastline, please check the conditions and tide times.
“Above all, please do not put yourself in danger.”
Sean Baxter added: “This is the second incident in a short space of time and is a great reminder to take care at the seaside.”
