Abeking & Rasmussen For Sale

90' Abeking & Rasmussen 1956 "Sea Diamond"


This is a Classic steel build, from Abeking Rasmussen with a traditional canoe stern and clipper bow that matches her timeless looks and shear lines of perfection. She is a World Classic Proper Yacht that has had Presidents, the Queen and many Celebrities as guests in her illustrious career.

Sea Diamond’s stunning interior is maritime elegance personified, featuring rich polished teak, raised paneling, high gloss teak & holly cabin soles, along with many luxurious materials including fine Italian leathers and exquisite marbles. A major refit ($ 6,000,000) between 2001 and 2004 saw a complete new interior installed, rebuilt from scratch by a team of fine marine craftsmen, in keeping with her design and history. In 2014, new furnishings and interior fittings were also added, enhancing her as-new condition with many custom art pieces incorporated. Other new additions included a full new teak deck, new electrical systems and new generators. Inside and outside, the yacht has many spaces for her guests to make use of. Her upper salon is home to a small dining table and leather seating, a desk and built-in television. A classic staircase leads down to the lower saloon which features a larger formal dining table to port, seating and a wet bar to starboard, connecting with the galley for easy service with a day head in the lower salon. Sea Diamond has been well maintained over her lifetime, it is clear as soon as you step on board that she is in stunning condition.
