SYNTHESIS 66 is a 137’2 (41.8m) classic 1982 Feadship. A recent extensive refit at Monaco Marine which began in 2020 through to 2022 has left her in immaculate condition. She has completed further works in Winter 2022 / Spring 2023. SYNTHESIS 66 is now a proud member of the Feadship Heritage Fleet.


Her interior was rebuilt during the extensive rebuild under the supervision of Boutsen, Monaco. The works retained her original woodwork, and paired with her new contemporary design, she now has a timeless classic ambience throughout.


Her main deck salon offers the primary interior guest relaxation area, in addition to large custom sofas is a games table aft. Forward of the salon, separated by glass panelling, is the interior dining room. Between the dining room and master cabin midships is a separate bar with seating for five.


Further forward on the main deck is the owner’s walkthrough — which can be closed off to create a separate cabin if required — leading into a spacious master stateroom complete with en-suite mosaic shower and double sinks, accessible via a dressing and vanity area. On the lower deck, a full beam VIP stateroom offer a separate lounge area, en-suite shower room, vanity area and queen-sized bed. A further three cabins, all with en-suites, include two convertible twin or double cabins and a twin cabin.


The masterpiece of the refit at Monaco Marine is found on her impressive aft bridge deck. A Jacuzzi can now be found forward surrounded by sun beds and seating. Two large lounge areas with sofas and teak occasional chairs on either side of this huge deck space add to the abundance of places to relax. Two units also on either side, both with large TVs, divide the area from the deck table. This table can be split into two smaller tables for more intimate gatherings or set as one large table for bigger groups. A large bar with seating for four completes the space. Above, the top deck houses gym equipment and a smaller seating area with comfortable leather sofas.


Up to 9 crew can be accommodated in 5 cabins, including a captain’s double cabin aft of the bridge and 4 further cabins on the lower deck, 3 twins and single cabin.


SYNTHESIS 66 has a range of 3,500nm from her Caterpillar engines. She is now in class with Lloyds and MCA compliant.
