A lifeboat is on scene helping a boat that ran aground around two miles off the coast of Old Hunstanton.
Humber Coastguard operations centre received a 999 call from one of the two people aboard the pleasure vessel at 9.20am today.
A coastguard officer said the Hunstanton lifeboat had launched and was waiting for the tide before assisting the vessel to shore, while coastguard officers monitor the situation from the clifftop.
