These are some of the eye-catching luxury facilities on board the superyachts that will be on display at the Monaco Yacht Show. More than 120 of the priciest private vessels in the world will be on show over four days at historic Port Hercule, starting on September 23.

The 25th edition of the event in glamorous Monaco brings together manufacturers, owners, buyers and enthusiasts at what is considered the most prestigious pleasure boat show in the world.

With more than 33,000 people expected to attend, these are some of the most expensive vessels for sale, according to MatrixLloyd, a leading authority on superyacht deals.

Built by Amels in 2011, this 65.7-metre (215.6ft) motor yacht features a lift that transports guests between decks, and a helipad.

Imagine sleeps up to 12 guests, who can lap up the sunshine on the spacious top deck, relax in a hot tub or exercise in the jet-stream swimming pool.

With a cruising speed of 14 knots (16.1mph), the vessel also boasts a gym, steam room and balconies on the two upper deck VIP cabins.

For those who can’t afford the asking price, Imagine was available for charter in the Mediterranean over the summer for £388,000 a week ($597,000), according to Fraser Yachts' website.

It is available for the same price over the winter, when it will be positioned in the Caribbean. 

Ten guests can sleep comfortably in five en-suite cabins, including a master suite with a double bed, study, walk-in wardrobe, his and hers bathrooms and separate toilet en-suite.

Built in 2005 and refit in 2009, the superyacht has a master suite that is forward on the main deck, with panoramic views of the sea.

Guests can go for a soak in the 55.5-metre (182ft) vessel's hot tub, or let loose with a large collection of water toys, including inflatable boats, personal watercraft, kayaks and dive equipment.

From the outside, Steel doesn't have the same appearance as a typical superyacht, but it was designed and constructed to go everywhere.

Built at Pendennis’ shipyard, in Falmouth, Cornwall, in 2009, the vessel is suitable for icy waters and can accommodate up to 12 guests in six staterooms, said Ocean Independence.

The 55-metre (180.5ft) expedition yacht has a stately interior that includes a fitness room, and a top deck with a hot tub and room for a small boat.
