Wayne Barrett has been building boats for 50 years, many of them world renowned. His latest venture is a DIY trimaran kit that embodies his half-century of expertise and celebrates “the joy of building and sailing your own creation”.

The versatile M80 can be speced for cruising or racing and the larger 9-metre design will have a range enough to sail across the Atlantic. The concept arose from Barrett’s belief that sailing should be within everybody’s reach. The main attributes of the design that have such broad appeal are its simplicity and economical package.
“I’ve built quite a few complicated, high-performance multihulls over the years and I’m aware they consume time that’s way beyond what an amateur could devote to a build. I used the The DuFLEX flat panel concept, adapted to tri design and put it out there for amateur or professional builders"
Getting started is straightforward, according to Barrett. “People buy the plans, complete with DXF files and they can have all the flat components cut out with CNC or jigsaw by hand”.
For the M80 currently in build at Lightwave Yachts, on Queensland's Gold Coast, the main shell structure, fore and side decks, and cabin sides were built with DuFLEX/foam panels cored with Divinycell H80 structural foam in a variety of thicknesses and reinforced with double bias E-Fibreglass skins.
The cabin top and floats were strip planked with DuFLEX H80 strips with a 450grm uni-directional on either side to achieve the compound shapes and then reinforced with additional laminates to complete the structure.
The project incorporated carbon fibre and E-fibreglass reinforcement, supplied by ATL, to provide stiffness and to achieve the weight specification for the project.
High performance KINETIX R246TX, a thixotropic epoxy, was used to laminate these reinforcements and WEST SYSTEM R105 and H206 was used for all bonding and coving, combined with WEST SYSTEM 413 Microfibre Blend and 411 Microsphere Blend powder modifiers to alter the consistency for the specific applications.
The M80 was faired with ATL’s unique Technifill XP which is a pre-filled epoxy fairing compound that is ultra lightweight and very easy to sand.
