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.

Lighter Stronger, Faster

What are the obstacles to having more fun and getting better performance out of our boats and how might we overcome those obstacles?

I’ll be giving a presentation at the Multihull Yacht Club of Queensland in Brisbane along with two esteemed composites engineers from CCG/Diab who have been crunching the numbers on some of our latest designs.

 

The presentation is on Thursday Feb first 2018. Full details of the presentation here:



New Cat Coming

We have a brand new cat on the drawing boards. It's a mini cruiser with some cool styling and the potential for some pretty sharp performance. Martin Vanzulli (yes that Martin;  www.catsailingnews.com ) suggested we take our Flying Fish 11 and trim it down a bit, add a hard top and some fresh styling and see if we had something worth posting on the w's. Well we think it turned out OK - heck I even put my name on it!

Any pro builders out there looking for a new project in this size range please let us know- we're keen to talk to you. See more images here:



Surviving Maria

Many boats were lost in the twin hurricanes that battered the Caribbean in September 2017. Fortunately Larry Ketten's TR40 Morello was not one of them. Larry has generously described his preparation for the storm and sent us some photos of the set up that saved Morello.

Read how Larry prepared Morello and survived winds that registered up to 173 knots.

 



 

Time has Come is a story in two parts about a new racing trimaran on the Australian circuit, Put together by Tony Grainger with assistance from Time Machine's owner Matt von Bibra, it refers to Time Machine's design heritage, its history, and provides some interesting details about the design.

ULLMAN SAILS IS AUSTRALIAN MULTIHULL CHAMPION 2017

Exceptional boat exceptionally well sailed. An exceptional combination that has once again seen Ullman Sails (previously Mad Max and also previous holder of the title) take out the Australian Multihull Championships in a competitive fleet of twelve boats sailing on Moreton Bay.

Congratulations to skipper and crew.

Thanks to Tony Considine for the photo.



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

Work is under way on the first TR36 at Currrent Marine in South Africa and we will have some new renders to publish in the coming weeks. Here's the first one.



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. www.graingerdesigns.net/build/partners-network
