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.


Raku 48 Goes Electric


A new Raku 48 to start construction in Capetown is planned for an electric regenerative drive system from Oceanvolt. The design will use an aft helm station and has been modified with more width to the cabin top allow for additional area for solar panels, with the additional benefit of more shade in the cockpit.
