Meet Project Sonata, a Rule-Breaking 351-Foot Sailing Yacht That Cruises Like a Luxury Liner

If ever built, sonata would be a first for sailing superyachts. it would have high-tech sails, but would ride more like a motoryacht., julia zaltzman, julia zaltzman's most recent stories.

What do you call a superyacht concept that takes the progressive learnings from the world’s leading new builds and packs them together in one visionary design? You call it Project Sonata. With three DynaRig systems inspired by the legendary sailing yacht Black Pearl , an inverted bow to slice through waves and enough space on board to compete with a motoryacht, could the 351-foot hybrid sailing yacht have it all?

The shipyard that built the ‘titanic’ has filed for bankruptcy.

Project Sonata is the work of emerging Swiss studio Valentin Design. Headed up by industrial designer Valentin Weigand, winner of Young Designer of the Year 2020, and naval architect Romain Acquaviva, the duo have their eyes set on a more sustainable, smarter, and buildable yacht.

“Our aim is to create a sailing superyacht that is more accessible to clients than the ones currently in the water,” Weigand told Robb Report . “Many clients are scared off by how complicated they perceive sailing yachts to be, requiring large numbers of crew and complicated rigs. We want to offer something that combines the joy of sailing with the ease and comfort of a motoryacht.”

Sustainability is also key to the concept. Two diesel electric engines generate recuperative energy through the yacht’s propellers while sailing, supplying enough power for the hotel load and to charge its Lithium-Sulfur battery pack. The 4MW batteries, developed by Oxys Energy, are free of heavy metals, such as cobalt, and are considered safer than Li-ion batteries.

The pair have strengthened their proposition by drawing on the expertise of Derek Munro, director at Divergent Yachting, who was instrumental in the construction of Oceanco ’s groundbreaking build Black Pearl .

“Derek has first-hand experience on what can be optimized or simply didn’t work with Black Pearl ,” said Weigand, “and we’ve worked that into the design of Project Sonata to eliminate those points.”

What works includes a 16-foot retractable keel that saves 6.5-feet of draft when required. The considerable DynaRig is low in maintenance yet highly durable, meaning a smaller crew is required. And, like Black Pearl , the tips of the masts can be unmounted to give enough clearance to sail under the Bridge of the Americas, and access the Pacific Ocean through the Panama Canal.

“ Black Pearl’s masts underwent three years of engineering and are proven to be highly efficient,” said Weigand. “By using the same molds on Project Sonata, we save time and money. In the same vein, the seating arrangement aboard Black Pearl is not ideal for heeling. We’ve ensured all exterior decks have been designed with heeling in mind.”

That said, Project Sonata has also undergone computational fluid dynamics studies to ensure it performs when sailing without heeling too much. “Most sailing superyachts’ main functions are regattas, which means they are super-fast, super light and heel a lot,” Acquaviva told Robb Report . “This can be really scary for owners who are used to stability and comfort, so our design prioritizes the guest experience. Our inverted hull extends the waterline length and cuts through waves.”

At 2,992 gross tonnes, the interior volume is sizable, complemented by features that follow the current trend for a connection to the outdoors. “The only thing our design lacks is a large swimming pool, which requires too much space on a sailing yacht,” said Weigand. “We’ve mitigated that with multiple exterior platforms to access the sea itself.”

A large sun deck affords alfresco dining. On the interior, glass is king, creating a design without visual borders. The master stateroom, spread across two decks, is virtually encased in a glass bubble. The VIP cabin enjoys direct access to its own private beach club, making a novel charter proposition. A double height atrium in the formal dining area speaks of elaborate guest entertainment. This also supports the studio’s intention to make the forward areas formal, so as guests move aft the more causal the design becomes.

Project Sonata, presented to the world by Ocean Independence, is a bold proposal from a studio made up of keen sailors, but whose sailing yacht designs to date have been limited to the 50-foot range. But that hasn’t deterred the dynamic pair.

“I’ve been sailing on boats since I was kid and worked in refit and construction for over 12 years,” said Acquaviva. “I understand what an owner wants from a sailing yacht, but equally what the crew need. When combined with visionary design and fully engineered naval architecture, we believe that’s a winning formula.”

Sonata 6.7 is a 21 ′ 11 ″ / 6.7 m monohull sailboat designed by Gary Mull and built by Sonata Yachts (AUS) starting in 1986.

Rig and Sails

Auxilary power, accomodations, calculations.

The theoretical maximum speed that a displacement hull can move efficiently through the water is determined by it's waterline length and displacement. It may be unable to reach this speed if the boat is underpowered or heavily loaded, though it may exceed this speed given enough power. Read more.

Classic hull speed formula:

Hull Speed = 1.34 x √LWL

Max Speed/Length ratio = 8.26 ÷ Displacement/Length ratio .311 Hull Speed = Max Speed/Length ratio x √LWL

Sail Area / Displacement Ratio

A measure of the power of the sails relative to the weight of the boat. The higher the number, the higher the performance, but the harder the boat will be to handle. This ratio is a "non-dimensional" value that facilitates comparisons between boats of different types and sizes. Read more.

SA/D = SA ÷ (D ÷ 64) 2/3

• SA : Sail area in square feet, derived by adding the mainsail area to 100% of the foretriangle area (the lateral area above the deck between the mast and the forestay).
• D : Displacement in pounds.

Ballast / Displacement Ratio

A measure of the stability of a boat's hull that suggests how well a monohull will stand up to its sails. The ballast displacement ratio indicates how much of the weight of a boat is placed for maximum stability against capsizing and is an indicator of stiffness and resistance to capsize.

Ballast / Displacement * 100

Displacement / Length Ratio

A measure of the weight of the boat relative to it's length at the waterline. The higher a boat’s D/L ratio, the more easily it will carry a load and the more comfortable its motion will be. The lower a boat's ratio is, the less power it takes to drive the boat to its nominal hull speed or beyond. Read more.

D/L = (D ÷ 2240) ÷ (0.01 x LWL)³

• D: Displacement of the boat in pounds.
• LWL: Waterline length in feet

Comfort Ratio

This ratio assess how quickly and abruptly a boat’s hull reacts to waves in a significant seaway, these being the elements of a boat’s motion most likely to cause seasickness. Read more.

Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam 1.33 )

• D: Displacement of the boat in pounds
• LOA: Length overall in feet
• Beam: Width of boat at the widest point in feet

Capsize Screening Formula

This formula attempts to indicate whether a given boat might be too wide and light to readily right itself after being overturned in extreme conditions. Read more.

CSV = Beam ÷ ³√(D / 64)

Lifting keel version also available.

Review of Sonata 6

Basic specs..

The hull is made of fibreglass. Generally, a hull made of fibreglass requires only a minimum of maintenance during the sailing season. And outside the sailing season, just bottom cleaning and perhaps anti-fouling painting once a year - a few hours of work, that's all.

The boat equipped with a masthead rig. The advantage of a masthead rig is its simplicity and the fact that a given sail area - compared with a fractional rig - can be carried lower and thus with less heeling moment.

The Sonata 6 is equipped with a swing keel. A swing keel is a pivoting lifting keel, allowing to sail both coastal and inland waters.

The boat can sail close to the beach as the draft is just 0.24 - 0.34 meter (0.79 - 1.09 ft) dependent of the load. See immersion rate below.

Sailing characteristics

This section covers widely used rules of thumb to describe the sailing characteristics. Please note that even though the calculations are correct, the interpretation of the results might not be valid for extreme boats.

What is Capsize Screening Formula (CSF)?

The capsize screening value for Sonata 6 is 2.15, indicating that this boat would not be accepted to participate in ocean races.

What is Theoretical Maximum Hull Speed?

The theoretical maximal speed of a displacement boat of this length is 5.6 knots. The term "Theoretical Maximum Hull Speed" is widely used even though a boat can sail faster. The term shall be interpreted as above the theoretical speed a great additional power is necessary for a small gain in speed.

The immersion rate is defined as the weight required to sink the boat a certain level. The immersion rate for Sonata 6 is about 73 kg/cm, alternatively 412 lbs/inch. Meaning: if you load 73 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 412 lbs cargo on the boat it will sink 1 inch.

Sailing statistics

This section is statistical comparison with similar boats of the same category. The basis of the following statistical computations is our unique database with more than 26,000 different boat types and 350,000 data points.

What is Motion Comfort Ratio (MCR)?

What is L/B (Length Beam Ratio)?

What is a Ballast Ratio?

What is Displacement Length Ratio?

What is SA/D (Sail Area Displacement ratio)?

Maintenance

When buying anti-fouling bottom paint, it's nice to know how much to buy. The surface of the wet bottom is about 14m 2 (150 ft 2 ). Based on this, your favourite maritime shop can tell you the quantity you need.

Ocean Independence reveals 107.35m DynaRig sailing yacht concept Project Sonata

Related articles.

Ocean Independence has revealed a 107.35 metre DynaRig sailing yacht concept named Project Sonata.

Advertised with a build time of 38 months, Project Sonata was designed by Valentin Design, which was briefed to “create a buildable, eco-friendly superyacht of tomorrow” in collaboration with German shipyard Lloyd Werft Bremerhaven.

Built from a steel hull and aluminium superstructure, Project Sonata will be powered by twin 1100kW electric engines for a top speed of 17 knots and cruising speed of 15 knots.

Project Sonata boasts “strong, confident lines” which “merge with sleek surface transitions,” the broker said, resulting in “a truly unique design”.

Elsewhere, the yacht features battery packs capable of powering the hotel service for 12 hours without the need for generators and a retractable keel for a reduced draft. Further energy can be recovered through the propellers while sailing.

Accommodation on board is for a total of 12 guests in six staterooms and a staff of 31 crew.
