A luxury superyacht being used filming for a Keira Knightley movie remains docked at Portland.

The Savannah yacht is an 83m luxury motor mega yacht.

The multi-award-winning superyacht was built in 2015 and can be chartered out for an eyewatering price of €1,000,000.

It is also multi-award winning, earning three awards at the 2016 Showboats Design Awards and a further two at the 2016 World Superyacht Awards.

The yacht can fit up to 12 guests and 24 crew members on board with one master suite, one VIP suite, two double rooms and an additional two double/ twin rooms.

Multiple swimming pools can be found onboard, including a large infinity pool on the aft deck.

The luxury doesn’t stop there as there is also a spa area where visitors can get a massage, as well as an extensive gym and a ‘Nemo Room’ which is an underwater lounge that is the perfect spot to try out a bit of fish-spotting.

Alternatively, the Nemo Room also doubles up as a cinema.

The Savannah is Feadship’s first ever hybrid yacht and is registered under the flag of the Cayman Islands.

The vessel is currently being used in filming off the Dorset coast.

It is believed that the filming is for a film adaptation of Ruth Ware’s bestselling novel ‘The Woman in Cabin 10,’ which sees Keira Knightley take on the lead role of a travel journalist.
