The LAB is a space where we explore ideas in construction, engineering and design technology. It's a space where we publish articles and ideas to deliver a better experience for those who build and sail on our boats. And please excuse me if we throw in a few random thoughts here and there. Welcome to the LAB



In 1990 we introduced a new float shape for our trimarans we called the V90. It was deployed on the TR series and later as the shape evolved adopted on other trimarans including Trilogy and the Essential Eight.


In 2017 we introduce a new float shape design to improve performance and possibly make for a drier ride when pushing hard in a choppy sea. Read the full article here:

Float or Fly- Foils in the mix at Airlie and Hammo

For the first time in OMR racing a fully foiling cat mixed with the action at Airlie Beach Race Week and Hamilton Island race Week 2016. So how did the GC32 perform against the other boats competing and what are the implications, if any, for the OMR?

Optimising Hull Lines for Performance

The lines the 8.5m Livewire sports cat raised a question about the kink in the rocker line. In this article I've addressed the top of rocker profile, hull fineness ratio, and importance of asymmetry in the water planes for pitch damping. See the article here

What Makes Max Fast

Mad Max has been dominating the inshore race results in Australia for quite some time now and is the current title holder (2015) of the Australian Multihull Championships having won the series on OMR and taking line honours in every race. 

So what makes Max Fast?

Multihull Performance - how fast really?

We all know about the bar talk and some of the wild claims that are made about boat performance. 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.

Where are the mid sized multis - the case for a class 40 trimaran?

In the 2015 Fastnet Race high performance multihulls dominated the elapsed time results but multihulls were poorly represented in the under 60' LOA size range. Where were the multihulls in the mid size range? We take a look and make some suggestions.

Building hours for multihulls

Building hours can vary considerably from one yard to another, but also from one boat to another in the same yard, even when the designs are very similar. 

Building hours are difficult to nail down but we provide some pointers in this article.

Secondary Bonding in Perspective

When composite components come unstuck the type of epoxy that was used sometimes gets held up as the bad guy. It may not always be the case. In fact in many cases its far more likely that the issue of secondary bonding is at the core of the problem.
