A man and a woman have been rescued after their yacht ran aground near Swanage in Dorset in the early hours.
An emergency message was sent from the 36ft (11m) vessel Summer Song at Peveril Ledge. It was taking on water after having been blown on to rocks and was in danger of sinking.
Two Swanage RNLI lifeboats and coastguards rescued the couple and brought them ashore unharmed.
Their yacht suffered significant hull damage, which hampered recovery.
Dominic Lonsdale, Portland Coastguard watch manager, said: "Within 40 minutes of the initial mayday call the casualties were safely ashore, with an ambulance en route.
"With strong easterly winds and the yacht being pounded onto rocks, this was certainly an immediate call for help.
"The yacht has now been washed up onto the eastern ledge and is hard aground heeling over.
"The Swanage lifeboats are still on scene however, and there appears to be significant damage to the hull of the vessel so recovery may be difficult."
