CLASS 6 O YACHT

O YACHTS CLASS 6 — HIGH PERFORMANCE CARBON CATAMARAN FOR SALE
Semi Custom Design • Carbon Construction • Wave Piercing Spine Concept
The Class 6 is a rare breed: a true high performance sailing catamaran capable of 10+ knots in light winds and 20+ knots under sail thanks to her ultra light carbon structure, advanced hydrodynamics, and the exclusive central wave piercing Spine Concept. Designed for owners who refuse to choose between comfort and speed, she delivers the living volume of a luxury cruising catamaran with the performance profile of a racer.
This is a yacht built for serious sailors, long range cruisers, and owners seeking a semi custom platform that can be tailored to their lifestyle, aesthetic, and performance ambitions.
ENGINES - Three Options :
100% Diesel : 2x Yanmar 80hp on sail drive
Smart Hybrid : 1x Yanmar 80hp on sail drive + 1 electric engine 20kW
100% Electric : 2x electric engines 20 or 30kW.
By chosing electric engines, the shipyard recommends to install DC 48V diesel generator for security.
KEY SELLING POINTS
• High performance sailing: 10+ knots in light air; easily 20+ knots without engines (inferred from design, weight, and sail plan).
• Ultra light carbon construction for maximum stiffness and acceleration.
• Exclusive Spine Concept: a central wave piercing hull that increases buoyancy, reduces pitching, and enhances safety.
• XXL 44m² platform with exceptional living volume for a performance cat.
• 100% semi custom interior — owner chooses layout, materials, and design.
• Designed for short-handed sailing — ideal for a couple or owner operator.
• Perfect sea motion thanks to centered mast placement and longitudinal carbon beam.
• Exceptional safety: added buoyancy from the Spine keeps the bow up in heavy seas.
PERFORMANCE
The Class 6 is engineered to sail fast in all conditions, not just in ideal wind.
Why she’s so fast
• Carbon hulls + carbon longitudinal beam = extreme rigidity and low displacement.
• Wave piercing Spine Concept reduces drag and softens wave impact.
• Perfectly centered mast improves balance and sail efficiency.
• Optimised sail area to displacement ratio (28).
• Light displacement starting at 15T — exceptionally low for a 63ft cat with daggerboards (1.2M draught at anchorage and 2.6M when sailing)
Real world performance indicators
• 13.4 knots boat speed in performance trials.
• High Bruce Number (1.3) — typical of fast multihulls.
• Low D/L ratio (60) — confirms lightweight, high speed potential.
Translation for buyers:
This is a catamaran that moves in every breeze, accelerates instantly, and maintains high average speeds on passage — the hallmark of a true performance multihull.
THE SPINE CONCEPT — EXCLUSIVE TO O YACHTS
A defining innovation of the Class 6.
What it does
• Acts as a central wave piercing hull, absorbing and redirecting water flow.
• Adds buoyancy forward, keeping the bows up in heavy seas.
• Replaces the traditional mast bulkhead with a carbon longitudinal beam, allowing the mast to be perfectly centered.
• Provides extra rigidity from bow to stern.
• Functions as a third hull in extreme conditions.
All of this results in:
• Smoother motion
• Higher safety margins
• Better weight distribution
• More usable interior volume
