In 2016 we’re celebrating 30 years of designing high performance multihull yachts.
Thirty years of exceptional racing achievements that you can see on the racing results pages.
Thirty years of designing boats for cruising, for racing, for the sheer enjoyment of sailing.
You can see a catalogue of some of those designs, and a our current model range on the projects page.
We are also celebrating a proud record for the structural integrity of our boats and continue to search for even better engineering solutions for all structural elements in our boats.
We have prepared a web page listing all known structural issues with our designs since Born to Run was launched in January 1986.
There are two reasons for doing this. The first is so you know the truth about our safey record. The second is that it keeps us focused on structures and thinking of ways to improve structures.
The page can be found in our build section or you can access it directly here.
Design work for plans and kits for our new series of Flying Fish high performance cruising cats is now well advanced. The general arrangement drawings are complete and work is under way on the more detailed aspects of the designs.
Weight and Length Compared.
We all want light boats for great performance even if we’re not racing, but most of us don’t want to spend a lot of money on exotic materials, detailed engineering studies and technically demanding construction methods. So how light can we get our chosen design without breaking the bank or building a boat that might not stand up to a hiding in adverse conditions?
We use some readily available data to literally draw a line about what you can expect to achieve in terms of weight for a given length, and we discuss some of the things you need to do if you want to get the structural component of the boat under that line.
Mad Max has been dominating the inshore race results in Australia for quite some time now and is the current title holder of the Australian Multihull Championships having won the series on OMR and taking line honours in every race.
She beat the Seacart 30 Morticia across the line in 5 of the 7 races at Airlie Beach Race Week 2015 and in all six races at Hamilton Island Race Week 2015.
George Owen has been at the helm of Mad Max for several years now and I posed the question to George “What is it that makes Max so fast right now?"
George was very generous with his response and there’s a wealth of valuable advice in George’s comments for the keen racing skipper, or the cruising skipper who simply wants to improve their performance.
Is there a Case for a Class 40 Trimaran?
The big trimarans took most of the glory at the head of the fleet in the 2015 Fastnet Race, although Comanche seems to get along OK for a mono.
But in the under 60' size range there weren't too many competitive multihulls and it was the guys and gals on the Class 40's that were having all the fun.
What's the big attraction in the Class 40's and is there a role for a box rule for 40' multihulls to sail offshore races of this nature? Read more here:
