The designs on these pages are the culmination of more than thirty years of experience designing multihull yachts that have included production cruising boats, purpose driven racing designs and yachts that are simply a vehicle for a lifestyle on the ocean.

They bring together the skills and the passions of world leaders in materials technology, composites engineering, sailmaking, rig building and the other technologies of modern yachts. 

They reflect my passion for the magnificent craft of the Melanesian and Polynesian explorers. They’re inspired by the flight of birds, the creatures of the ocean and the dynamics of their motion in the sea and the air.

If you share my inspiration and you’re looking to bring your own vision to life let’s start a dialogue.

George Owen has been at the helm of Mad Max for several years now and I posed the question to George “What is it that makes Max so fast right now?"

George was very generous with his response and there’s a wealth of valuable advice in George’s comments for the keen racing skipper, or the cruising skipper who simply wants to improve their performance.

Is there a Case for a Class 40 Trimaran?


The big trimarans took most of the glory at the head of the fleet in the recent Fastnet, although Comanche seems to get along OK for a mono.

But in the under 60' size range there weren't too many competitive multihulls and it was the guys and gals on the Class 40's that were having all the fun.

What's the big attraction in the Class 40's and is there a role for a box rule for 40' multihulls to sail offshore races of this nature?
