The classic Feadship SYNTHESIS 66 is a 137’ (41.8m) motor yacht of exceptional pedigree. Built in 1982, she is an impressive member of Feadship’s heritage fleet. She recently completed a major rebuild over three years at Monaco Marine, bringing her back into Lloyd’s classification—an impressive feat—and now enjoys modern amenities and a fresh design.
SYNTHESIS 66 is a bright and airy yacht, ideal for those looking to relax and entertain. A home away from home, her interior update has taken advantage of her large windows with a palette of light, neutral shades. Her interior refit was overseen by Boutsen Monaco who retained her original woodwork, which, paired with this new contemporary design, has provided the yacht with a timeless, classic ambiance throughout.
However, the masterpiece of the refit is undoubtedly her newly redesigned bridge deck. A Jacuzzi can now be found aft surrounded by sun beds and seating. Forward is an alfresco dining area that can be split into two distinct tables or combined for bigger groups. A large bar completes the space. Above, the sundeck houses gym equipment with pilot seats for guests to enjoy whilst cruising.
SYNTHESIS 66 can comfortably accommodate up to 10 guests across five beautiful cabins. The owner’s full-beam master cabin can be found on the main deck through a private walkthrough—which can be converted into an additional cabin if required. This master suite contains an en-suite with a playful mosaic design, accessible via a dressing and vanity area. Her guest suites include a full-beam VIP stateroom with a separate lounge area, queen bed and vanity area; two convertible twin or double cabins and a single non-convertible twin cabin. All of her cabins feature en-suites and ample storage. She also has an additional five cabins for up to nine crew, including a captain’s double cabin aft of the bridge, and another four on the lower deck: three twins and one single.
