Bieker Moth goes into Production

The Bieker Moth, built in New Zealand by LSF Composites set for production in August.

Moth sailor Scott Babbage, who developed the broad concepts for the boat, informed Sailweb.co.uk that following the sailing trials over the next weeks, five boats would be built in 2018, with the capability to produce 2 per month from January 2019.

The Bieker Moth will retail at $39,000 NZD (equal to £20,074 or $26,667 or €22,687) ex taxes for the platform, foils, fittings and ropes, trolley and covers - see orrder details below.

The design and prototyping for the Bieker Moth has been underway since the 2017 Moth Worlds in Italy, and the first boat will launch in New Zealand at the end of July, with testing continuing in Sydney.

The Bieker Moth team have adopted a no-compromise approach to design and construction.

The hull is a comparatively high volume displacement shape, with a rocker profile for easy low ride handling and un-sticky takeoff characteristics.

The platform concept minimises aerodynamic drag and heeling moment, with minimal tramp area. Stiff single piece wing beams located in rebated deck sockets maximise effective beam when heeled to windward through a curved, high angled shape.

The boat has been designed with a deck-sweeping rig in mind. Building on recent trends in the class, the layout allows for a long deck/sail seal. A concealed control system and control line configuration makes for a clean deck layout.

For backward compatibility the boat has also been designed to use a conventional full-height rig.

The foils have been engineered to be as stiff and long as modern materials and production processes allow.

The boat can fly higher out of the water, and has a larger vertical range to deal with both deceleration during foiling tacks and larger waves downwind.

With 3D printed titanium components, the foil section thicknesses have been reduced for minimum drag at sailing altitude.

The horizontals are aggressively high aspect with low wetted area.

The experienced build team at LSF Composites with their extreme attention to detail and no compromise on quality, is targeting the Bieker Mothat the top end of the Moth fleet.

The centreline-joined hull is built from pre-preg carbon fibre on a nomex core. The hull is available in a variety of finishes, from painted, to an unbelievable clear coat carbon.

The foils are are available in high or ultra-high modulus pre-preg carbon for incredible stiffness.

Using state of the art production techniques, the single piece foils are cured at high temperature and pressure in an autoclave with precision alloy tools. The foils come faired, finished and ready to race.

The wing beams are high modulus pre-preg carbon, constructed as a single piece using bladder moulding.

Designed to eliminate the need for compression struts and unnecessary joins, the rigid wing frame reduces windage and streamlines the platform.

The Bieker Moth will continue to evolve based on feedback from the sailors, with new ideas and improvements from the designers and builders.

The team behind the Bieker Moth capitalises on a diverse background in high performance boats, from the America’s Cup to i14s, foiling kites, 18’ skiffs and Moths.

Scott Babbbage has been a Moth class stalwart for the best part of 20 years, finishing 10 times in the top 10 at the World Championships.

Babbbage approached Paul Bieker, Riley Dean and James Gell to collaborate on the Bieker Moth project.

Keen to take the Moth to the next level, Babbage developed the broad concepts for the boat. Babbage knows how to sail a Moth fast, and will be the test pilot, putting the boat through its paces.

Seattle-based Paul Bieker has been a pioneering designer in the i14 class, with multiple World Championship winning designs over two decades.

Bieker was a designer for Oracle Team USA in the 33rd, 34th & 35th America’s Cups, collaborating on the design and structures behind the foils for the 100’ trimaran, AC72 and AC50.

While working for Oracle Team USA in Bermuda, he came up with the concepts behind the Bieker Moth and drafted the shapes, foils and structures for the boat.

Design engineer Riley Dean is an 18’ skiff skipper and keen kite foiler from Auckland.

Currently working for the American Magic team for the 36th America’s Cup, Dean designed the tools and components for the Bieker Moth.

Boat builder James Gell started LSF Composites in Whakamarama, New Zealand following his work with Softbank Team Japan in the 35th America’s Cup.

A fellow 18’ skiff sailor and foil kiter, James builds and assembles the Bieker Moth at his LSF factory using boat building experience and processes gained throughout his diverse career.


A fibreglass shipping box, additional foils and clear coat finishes are optional extras. Foils are not sold separately.
