A WEALTHY businessman whose identity is shrouded in mystery has just taken possession of his Hampshire designed floating palace estimated to cost at least £70m.

Bosses at New Forest super yacht visionaries Michael Leach Design are to see their latest lavish creation sail into the Solent today.

The 67-metre long yacht Anna, is set to become a familiar sight in the world's most glamorous harbours, but is stopping off for a day in Portsmouth so crew and designers can show it off.

Built over more than three years in Holland, capable of 17 knots, with a crew of 17 and ranked as 87th biggest in the world, Anna is to be based in the Mediterranean.

She boasts four guest bedrooms and a VIP cabin, a gym, a jacuzzi and a helicopter landing pad.

Although its secretive owner refuses to allow any pictures of its opulent interior, the design is said to be extravagant even by the considerable standards of the superyacht industry.

Everything, from door handles to light fittings, has been hand-made and is of bespoke design by craftsmen. Mother of pearl inlays sit alongside wooden floor mosaics, while other rooms have handmade carpets.

Mark Smith, director at Michael Leach, said: "It is four years of hard work. When you are dealing with a boat like this everything is handmade and everything is designed.

"Inside there is lots of very fine detailing. It is extraordinary craftwork, just stunning.'' Mark who, together with Michael Leach, heads up the four strong Brockenhurst and Romsey based firm, says the size of the yachts they're asked to design is increasing.

"Nowadays this is a regular sized boat. When we started 50m was considered big," he said. "It is going to be good to see it in the Solent. We will take our families down and have a nice day."

Anna is far from the biggest project undertaken by the design team, which has previously designed a 72m yacht for the king of Saudi Arabia's brother. Now they are working on four projects that size or bigger, including one 125-metre monster yacht.
