Class 4

Enjoy the magic

Easy – Solid – Fast

Class 4 is a pure Lerouge Yachts Design catamaran. With over 1500 catamarans sailing over the world on Lerouge design, you have a proven solution. If you pay attention to owners, they all are real sailors and most of them went World Tour.

O Yachts added on this Lerouge Design a specific aft platform and O Yachts “roof wave style” look (Thanks to designer DENN Clifford).

Go fast, go far … with pleasure

Our Class 4 is a wonderful platform for anyone looking for a fast and easy to sail catamaran (short handed) ; able to achieve over 250miles/day in comfort.

Class 4 is a fast yacht with a light displacement of 6700kg thanks to the quality of workmanship, composite material and brands used. She will definitely shine in any race with a slim hull achieving exceptional upwind capability. Performance is key for security and stability during long passages

Most catamarans are sold during boat shows. But in a boat show … you do not face huge waves … you do not have to go upwind for hours … you do not have to go fast to run away from bad weather … and you do not feel bad due to an unbalanced catamaran. If you did, you would certainly go for an O Yachts proven model.

Strong as a rock

Few boat builder offer a carbon reinforced structure as standard. Carbon is used for the front and central beam, bowpole, mast pilar, pilar beam, aft beam. As standard we also include kevlar shield on hull.

Even less boat builder laminate by hand all composite panels that are not structural ; this way, they become structural after hand lamination. The process represents hundreds of labour hours. Sofa, kitchen, stairs, floor, bed, are structural and will not produce a single “crack” when you walk on the boat at night.

How fast ? #1 multihull ARC 2014

Fact : sister ship raced ARC 2014 ; finished #1 in the multihull real time category. Maximum speed of 27kts. Class 4 is a proven winner.

Class 4 go upwind 20% faster than wind from 3 to 9kts. You will be one of the very few not to turn on the engine when there is light wind.

Then when wind is about 10 to 15kts, you will be over 10kts. At 20/25kts, you will go driving for 14 to 19kts with reduced sails area in perfect comfort as Class 4 is perfectly balanced

Bare or Complete

O Yachts is one of the very few to offer :

Bare (composite finished)
Motor away (ready to leave shipyard)
Complete (custom finish)

Sailors as Francis JOYON and other came to us to buy motor away catamarans. Then leave shipyard with minimal sail or motor to finish the dream boat by themselves. They have better budget with a perfect shell, any money they invest is not lost. Other good point : they know there boat perfect.
