Request Pre-Charter InspectionAbout SYNTHESIS 66
SYNTHESIS 66 is a 41.80-metre custom displacement motor yacht built by Feadship in 1982 with exterior design by De Voogt and interior design by Larvor, refitted as recently as 2023. Her steel hull and Feadship provenance place her within a lineage of Dutch craftsmanship that has remained a reference point for build quality over several decades. With a gross tonnage of 347, a cruise speed of 12 knots, and a range of 3,500 nautical miles, she is a composed long-range cruiser suited to the considered itinerary rather than rapid repositioning.
Available for yacht charter along the French Riviera, the Amalfi Coast, Corsica, Sardinia, Ibiza, Monaco, and the broader Western Mediterranean, SYNTHESIS 66 accommodates 10 guests in 5 cabins attended by a crew of 8. The 2023 refit is a material consideration: it signals active investment in a hull that now carries over four decades of Feadship engineering, bringing her systems and presentation to a current standard.
She carries a deck jacuzzi, sun deck, sunpads, outdoor shower, exterior bar, swimming platform, and Wi-Fi. Her water sports programme is well stocked for a vessel of this era and footprint: three Seabobs, Yamaha and MXR Jetsurfs, Yamaha FX waverunners, an inflatable trampoline, wakeboards, doughnuts, fishing equipment, and snorkelling gear for ten.
SYNTHESIS 66 will appeal to guests with an appreciation for heritage yachting — a Feadship with decades of ocean miles and a recent refit is a specific and legitimate proposition. She suits mature parties and families who value character, stability, and proper crew service over novelty. Those who require the latest interior design language, new-build systems warranties, or a high-volume amenity programme will find that a younger vessel better matches their expectations.
The provisional rating is based on available public data, reflecting acceptable standards across safety documentation, maintenance records, and operational protocols.
