One of the more secretive superyacht projects in recent years — the 73m (241ft) Pegaso — has had her final hand-over.

Built by the family-run Friere Shipyard in Vigo, Spain, Pegaso was due to be delivered just prior to the Monaco Yacht Show last September, but she encountered problems when her stern thrusters malfunctioned and she ended up hitting rocks close to the dock.

Classed as a research vessel, Pegaso has her own submarine, an ice-class steel hull and a commercially compliant helipad — along with a 10,000nm range.

Few details are known about her interior, other than that Mark Berryman Design was hired to outfit her six staterooms and accommodations for 27 crew. The owner's suite is reportedly about 1,292 square feet (120 square meters).

Pegaso was listed for sale a few months ago but is no longer on the market.

As for her owner, a look at the superyacht's transom gives it away.

A horse's head, with wind-swept mane, graces it — the same design as the logo of Grupo Pegaso, the Mexico-based telecommunications company.
