An investigation has been launched after a lifeguard vehicle got stuck in sand and partly submerged by the sea on a Cornish beach.
The patrol vehicle was unable to move after lifeguards advised bathers at Booby's Bay, near Padstow, on Sunday.
The RNLI said the tide came in too quickly for it to be towed out. The vehicle, which is now a write-off, was recovered on Monday.
A full investigation would take place, the charity added.
RNLI Lifeguard Inspector Steve Instance said: "This is an isolated incident which highlights the power of the sea.
"Thankfully on this occasion no-one was hurt. However, there will be a full investigation into the incident and any lessons to be learnt will be incorporated into the 4x4 training the lifeguards receive."
