SYNTHESIS 66 Yacht for Charter

137' 2" (41.8m)

SYNTHESIS 66 is a classic 1982 build by the renowned Dutch shipyard Feadship. A recent extensive refit by Monaco Marine in 2022 has left her in immaculate condition, ready for the charter seasons ahead. She can accommodate up to 10 guests across five cabins, with an experienced crew of eight.

With her exceptional pedigree and at 137’2 (41.8m), SYNTHESIS 66 is an elegant and spacious option for large groups looking to relax and socialize on charter. Her interior is airy and bright thanks to a palette of light tones complemented by neutral carpets and soft furnishings. The refit left her original woodwork, and paired with her new contemporary design, she now has an updated classic, modern feel throughout.

This design works particularly well in her main salon. Located on the main deck and accessible via large sliding doors from the aft deck, the dining space is elegant and well illuminated thanks to large windows and unique glass paneling separating a lounge area with games table and plush seating. Moving 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 full-beam master stateroom complete with en-suite mosaic shower and double sinks, accessible via a dressing and vanity area. A VIP stateroom is also full-beam with 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 single non-convertible twin cabin.

However, the highlight of her two-year refit by 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. Thanks to this refit, she has now entered back into Lloyd’s class — an impressive feat.

Above, the topdeck houses gym equipment and a smaller seating area with comfortable leather sofas for guests to take in the breathtaking views while cruising.

With ample space to entertain coupled with her more private relaxation areas, SYNTHESIS 66 is an exceptional option for those looking to cruise the Mediterranean this summer. Seaworthy and safe, and with her excellent charter record and notable pedigree, guests can expect nothing less than an extraordinary charter experience on board.
