What we do

Multihull yacht design and construction has come a long way since I created my first design in 1986. Evolution never ceases in nature and there’s no reason for it to cease in yacht design and manufacture either. 


Our journey starts with asking questions and imagining whats possible.

We craft the curves, finesse the forms. We bring in the technicians, the mathematicians, sometimes the magicians. We call up the makers and the movers and shakers.


We’re here to bring you the latest in design technology in hull shapes, in styling, in engineering, to connect you with the products and the services that will streamline the build process and bring your own yacht life with the most cost effective build methods we can conjure. 


Browse the designs. Check out the people and the companies we’re partnered with in The Partners Network.


Join us on our journey, or let yours begin when ours is done.

What you’re imagining just might be possible.

And if it’s not we can probably make some magic happen anyway.

Not the first design but one of the first. And she's been first in fleet more than once. She's been called ATL/Oaks. Dux Nuts and Moving Finger. She'll always be called one of my favourites.

Latest Design

Mauritius is an Island. It's also a way to get to an island. Or if you have the inclination a whole number of islands. Mauritius is designed for fun, for exploring, for experiencing the world's oceans and the marine environment. You can see more of Mauritius here:

TR36 Work in Progress

Two highly accredited builders join our Partners Network

Two experienced and highly acclaimed Australian multihull boat builders have joined our Partners Network and are available to quote on custom projects.

They are Jamie Morris from Australian Custom Multihull Yachts and Julian Griffiths from Noosa Marine.

Jamie is no new comer to our designs, having built and more recently done a refit on Cut Loose.


Julian is yet to build one of our boats from the bottom up but he has a background in custom boats in the larger size range. Julian is well familiar with our designs having skippered Boatworks in the Brisbane to Gladstone Race and Hamilton Island Race Week in 2015.


Find the contact details for both of these builders in out Partner’s Network Page.
