Volunteers from Hunstanton RNLI were paged just after 5.30pm.
Fast inshore lifeboat Spirit of West Norfolk launched onto a rising tide within 10 minutes and made good speed to Scolt Head, near Brancaster.
On arrival the crew collected the women, who were aged in their 20s and 30s and both uninjured, before landing them on the beach at Brancaster, where HM Coastguard were waiting to receive them.
The lifeboat returned to station at 7pm, after which she was washed down, refuelled and made ready for her next service.
Notes to Editors
Hunstanton is one of Norfolk's busiest lifeboat stations, whose volunteers operate both the inshore lifeboat
Spirit of West Norfolk and search and rescue hovercraft Hunstanton Flyer.
They cover The Wash, a tidal estuary stretching for more than 100 square miles fed by five main rivers, along with parts of the north Norfolk coastline.
Like more than 200 RNLI stations around the coast of the UK and Ireland, the crew's lifesaving work could not be possible without the kindness of those who give donations or leave legacies to the charity that saves lives at sea.
