What is it that draws us to the ocean?

The ocean is a boundless canvas for travel and adventure. 

It can be cold with gales in the high latitudes, hot and windless in the tropics, and everything between.

There are more bays, harbours, coral reefs and islands than you can explore in a lifetime.

There is an endless variety of smells, colours, patterns and shifts in the breeze to amaze and delight.

We are blessed to be able to experience these sensations under sail.


Our yachts are some of the tools you can choose for the journey.

Our inspiration comes from the the ocean, the natural environment and the forces of nature

Our work is creating sailing yachts that inspire for their performance, their style and the lifestyle they afford.

Our focus is on using creative means to enhance the experience for those who build and those who sail.

Our mission is to find the materials, the technologies and the artisans to make that experience real.

We design the forms, the structures and the systems that make sailing yachts elegant, fast and fun to sail.

Increasingly the role of the designer is changing.

The work of the design of sailing yachts has become more complex and demanding on technological skills with the advent of CNC machining, robotics, additive manufacture, building information modelling (BIM) and most recently parametric design. 

As the technologies of building boats have evolved, so by necessity have the skills that apply those technologies.

In some respects yacht design is easier than when we used large drawings tables, lofting splines and tech pens that regularly clogged up and blotched the vellum if you gave them a shake.

mutlihull performance factors

How do you know how fast boats really are, and are the polar diagrams we see published in boat magazines and brochures a credible means to determine performance potential?

We've put together some information about the factors that determine the performance of multihull yachts and some of the ways that performance can be measured and predicted.

And we propose a more credible method for yacht manufacturers to promote the performance potential of their products.

See the article here:


With the increased integration of technology, new materials and more complex on board systems in yachts, the role of planning and management has become more critical than ever. 

How the process of planning and management is put to work in a project varies a lot depending whether the project is self managed by an owner builder, or is part of the production process of a large corporation where the boat is just one of many products under construction. And of course there is a whole range of possibilities between those two examples.

In every case however, regardless of the size of the project there is one basic factor that is most likely to determine the degree of satisfaction with the build process and its' outcome.

Deltaform is a research project based on the premise that a vessel supported by three hulls of identical or similar shape and buoyancy, configured with their centres of buoyancy in an equilateral triangle formation, will have a significantly smoother and more sea kindly motion than a conventional motor powered monohull, catamaran or trimaran.
