Originally built in 1962 in Bulgaria to carry passengers across the Black Sea, and then used for spying in the North Atlantic by the Soviet Union, La Sultana has gone on sale to potential buyers.

The vast vessel has been completely rebuilt to the high standards needed for a classic yacht.

La Sultana has seven large guest suites which can accommodate up to 12 guests and, according to yacht broker Camper & Nicholsons, has a similar pedigree to the famous Christina O, graced by presidents and celebrities.

The aim of La Sultana’s conversion was to preserve the authenticity and elegance of her glorious past, reconfigure the interior and exterior spaces, while integrating the most modern and advanced technology.

This ambitious restoration was led by a team of naval construction and navigation professionals under the leadership of the French naval architecture company Orion Naval Engineering, under the supervision of the RINA classification office and the flag authorities.

It was a colossal yet thorough project.

All seven suites have distinctive windows, marble baths and showers, as well as Wife and plenty of space to relax.

The owner’s suite is an enormous 66 square metres wide with panoramic views.

Facilities include three tender boats, including two Nantucket Limited Edition Sellerie By Lancel boats and an XPRO 490; a Mini-Moke jeep; an indoor swimming pool; outdoor Jacuzzi; a hammam; a Marina beach club; two jetskis; two kayaks; two windsurfing boards; diving equipment; a wakeboard; six bikes; wifi and on-board entertainment system.

On-board the six-deck La Sultana are many areas to rest and relax, including a large dining room, extensive lounge area with bar, two outdoor lounges which can be used for dining, and a top deck with outdoor shower.

The interior has been tastefully designed and includes works from famous Moroccan artist Jilali Gharbaoui and a unique sculpture made from seashells and previously displayed at an Hermes store in Paris.

Weighing 823 tonnes, she has a range of 5,000 nautical miles cruising at 11 knots and a top speed of 13 knots.

La Sultana has a crew of 17 people and is now for sale via Camper & Nicholsons.
