40m Astilleros M. Cies motor yacht Silentworld sold

19 May 2026 • Written by Lucy Pughe-Morgan

The 39.5-metre Astilleros M. Cies motor yacht Silentworld has been sold. Adam Blackmore of Camper & Nicholsons represented the seller, whilst Martin Hills from Alexander Marine Australia represented the buyer. 

Built in 2006 by Astilleros M. Cies to a design by Inigo Echenique, who also completed the interior design, Silentworld is Lloyds classed and sports a steel hull and aluminium superstructure. Her naval architecture was developed by Acubens and Inigo Echenique. She has been meticulously cared for since delivery, with her most recent refit taking place in 2018.

Silentworld was last asking $7,495,000

A 2023 interior refit has given Silentworld a more contemporary feel while preserving her warm, traditional soul. Interior design features dark woods and light upholstery throughout.

A spacious main saloon features a forward dining area along with a large sitting area with two sofas and two armchairs arranged around a coffee table.

Those with a love of the outdoors are well catered for with a dining area aft on the main deck, with a banquette, dining table and deck chairs complemented by ocean views.

The main deck master suite rivals those found aboard yachts over 50 metres, with large vertical windows and forward sliding doors that reveal an en suite clad in pink marble with a central bathtub. 

Below, a traditional four-cabin layout offers two doubles and two twins, with accommodation for six crew. An additional double cabin on the bridge deck offers additional flexibility and can be repurposed as a sixth guest suite, gym or office.

A second saloon on the upper deck offers dining space for four, plus seating on two sofas for additional lounging. 

There is also additional al fresco dining space on this deck, as well as sun loungers and chairs aft, all shaded by the deck above. 

Above, a large sun deck features a hot tub, sun pads and seating, benefitting from panoramic views. The deck also features two al fresco dining areas with optional shading for all-weather use. 

Silentworld comes complete with a 5.2 metre Valiant tender, a 4.5 metre Valiant tender and an 8.5 metre custom Blackwatch tender with capacity for 12 guests. Her extensive toy box includes 10 sets of dive gear, snorkelling equipment, two Seabobs, ski tubes, wakeboards, wakesurfs, a stand-up paddleboard, a glass-bottom kayak, inflatable and fishing gear.

Powered by twin diesel Caterpillar 720 hp engines, Silentworld has a top speed of 14 knots with a cruising range of 4,000 nautical miles at 10 knots.

Silentworld was last asking $7,495,000
