Her Majesty The Queen may have named two out of Cunard’s three ships, but her heart lies with a much smaller vessel. Since the Royal Yacht Britannia was de-commissioned, she has twice chartered Hebridean Princess for family summer holidays. The line is too discreet to reveal which suite she has occupied, but there are only 30 to choose from, carrying just 50 passengers in country house hotel luxury which belies the vessel’s origins as a Caledonian MacBrayne ferry. Cruising the Scottish coast and islands each summer, the ship makes occasional forays to the south coast of England. Excursions and gratuities included.
