The Feeling of Sailing Back Again
Sailing on Class 4 is above all, to get the spirit of cruising back again. Pleasure to go from bay to bay faster than wind with light conditions (7kts speed with 5kts real wind) or make long passages, in safety with amazing performances (300 miles/day)… without efforts.
Own a Class 4 that really matches your style, choose all options in details: interior design, rigging, steering, engines… O Yachts is master in semi-custom yachts, from best technical practice composite building, on female molds. Depending on your directions and options, Class 4 can target podium in racing, as well as offering easy sailing for cruisers.
Spacious Living Area


Saloon: Always custom depending on your preferences. We raise about 8 inches sofa area to offer perfect sea view when seated.
Chart table: Large and spacious to enjoy planning navigations.
Kitchen: Really made for those who love cooking with large cabinets, 2 deep bins, and large opened windows to communicate with cockpit.
Cockpit: You really take advantage of a large, deep cockpit to setup your way. You can easily have 10 people seating at table.
3 or 4 Cabins

Head
Very design with a large shower area.


Cockpit Area
New cockpit deeper than number 1 Class 4. You offer XXL space for guests and family. Feel free to design it your way: seating, benches, table… Below is an example with classic cockpit and table for 8 guests.



Bimini Protection
We always cut the bimini upon your desire. Usually Class 4 owners cruise in the Tropics and therefore ask for maximum sun protection. Very short bimini available for racers with perfect view on sail area.

Custom Steering
Your decision to steer your Class 4 and choose your seating area. Some prefer a classic starboard wheel on deck, with either 1-person seat or 2-person bench. Others prefer a more exotic solution with central raised steering wheel. We also offer manual steering with carbon tillers or combination wheel/tillers.

Aft cockpit station
Exclusive Aft Platform
Unique aft platform on Class 4. We link aft with a large 40-inch platform. Perfect to manage your Class 4 without stepping on guests, protected under the bimini in cockpit area. Curved davits perfectly fix tender for long passages.


Sail Plan
This is the engine of Class 4. 3 options to choose from:
- Cruising: 57.5ft Aluminium mast (17.6m)
- Performance: 59ft Fixed Carbon mast (18m)
- Race: 63.6ft Rotative Carbon mast (19.4m) - Up to 153m² upwind

On forward beam we propose a self-tacking jib lightly in the back. With light wind, you will prefer to use the Drifter (large genoa) that is tacked inside shrouds. Gennaker and Code0 are setup at the very end of the carbon bow-pole.
Engine Options
100% Diesel
2 Yanmar 30hp on saildrive. Max speed 10kts, cruising on one engine 7kts.
Smart Hybrid
1 Yanmar 30hp on saildrive + 1 electric engine (10 or 15kW).
100% Electric
2 electric engines 10 to 15kW. We recommend a Diesel 48V generator for safety.

Quality Composite
With 7.2T light displacement, Class 4 is one of the lightest sailing catamarans with CE. Weight is the Graal to offer a real sailing machine, ready to offer pleasure in light wind or gales.
At O Yachts, quality is not an option. As standard we offer Carbon structure:
- Front beam
- Bow pole
- Mast pillar
- Mast beam
- Kevlar shield (center to peak / 8 inch over water line)
UNIQUE! Forward Beam / Bow Pole 100% Carbon
Erik LEROUGE is one of the very few to ask for complete carbon beam connection between hulls and link to platform on center. Forward beam is not just a bolted 7-inch tube as most catamarans - you have 28 layers of carbon linking 4 hull sides. Then another 28 layers of carbon from bow pole to platform on trampoline center.

Bare Hull Delivery
You can finalize yourself a Class 4 to many steps of finish.
