The line announced earlier this month it would be scrapping its summer programme onboard Queen Elizabeth and replacing it with a new domestic schedule.
Voyages will sail roundtrip from Southampton between July and October, offering a mix of scenic British Isles cruises and several "sun voyages" which will see Cunard sail "to where the sun shines brightest".
Itineraries ranging from three to 12 nights are available, taking in England’s Jurassic coast, Land’s End and the Cornish coast, and Scotland’s Isle of Arran, Mull of Kintyre and Sound of Mull.
Four voyages will feature port calls, including Liverpool, Greenock, Invergordon, Belfast and Newcastle, as well as a maiden call for Cunard at the port of Holyhead in Wales.
A four-night scenic British Isles cruise with Cunard leads in from £599pp; 10-night cruises start from £1,299pp and seven-night sun voyages from £899pp, all based on balcony stateroom accommodation.
Cruises will go on sale on Wednesday (31 March) at 10am.
Cunard president Simon Palethorpe said: "Cunard’s summer at sea luxury UK voyages are a truly unique way for guests to have a much-needed break this summer.
"With international travel not yet fully opened up, we’re delighted to offer these voyages exclusively for British guests to experience a staycation unlike any other.
"Guests can sail along some of the most stunning coastlines anywhere in the world, or sail on one of our sun voyages where the destination is unscripted and is guided by studying the weather forecast and heading to where the sun shines brightest."
Cunard said owing to the "advanced progress" of the UK’s Covid-19 vaccination programme, and the "strongly expressed preference" of guests interested in the line’s UK coastal cruises this summer, all sailings onboard Queen Elizabeth this summer would be exclusive to UK residents vaccinated against Covid-19.
Travel insurance will also be mandatory for all guests.
The line has stressed all other Cunard voyages currently on sale do not currently have a vaccination requirement.
All guests and crew who sail with Cunard in UK waters this summer will be required to follow enhanced health and wellbeing measures; these include enhanced sanitation measures, social distancing and the wearing of masks in certain areas of the ship.
Crew will be subject to a strict testing and quarantine regime, as well as regular testing during their time onboard.
Cunard said the protocols could be subject to change to align with any new government or expert advice.
