Announcing the Bieker Moth

We’re proud to announce the launch of the Bieker Moth.

After a year of development from the team, we’re about to splash the boat for the first time.

The Bieker Moth Concept

Bieker Moth - Assembly


Despite continuous development, the Moth platform has been relatively static for over 20 years. The Bieker Moth could have been an incremental improvement on existing boats, but we decided on a more ambitious path.

We 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. Our horizontals are aggressively high aspect with low wetted area.

The BuildLSF Composites - Lighter, Stronger, Faster

The Bieker Moth is built in New Zealand by LSF Composites. With an experienced build team, an extreme attention to detail and no compromise on quality, the Bieker Moth is targeted at 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.

Our 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.

We’ve attained the highest standards of build quality, by selecting the best techniques and materials.

The Process

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

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

The Team

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.

Paul BiekerPaul Bieker - Oracle Team USA

Seattle-based Paul Bieker has been a pioneering designer in the i14 class, with multiple World Championship winning designs over 2 decades. Paul’s foils were instrumental in the i14 transition to foil-assisted sailing.

Paul 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.

Taking a keen interest in the Moth while working for Oracle Team USA in Bermuda, Paul came up with the concepts behind the Bieker Moth and drafted the shapes, foils and structures for the boat.

Riley Dean

Riley is an 18’ skiff skipper and keen kite foiler from Auckland. As a design engineer for Oracle Team USA at Core Composites for the 34th and 35th America’s Cups, Riley is been responsible for turning design models into build processes and final parts.

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

James GellJames Gell - LSF Composites

LSF Composites in Whakamarama, New Zealand, was started by boat builder James Gell following his work with Softbank Team Japan in the 35th America’s Cup. James has been a boat builder for over 16 years and has extensive experience in building high performance yachts, building everything from Olympic classes, to offshore race yachts and numerous America’s Cup boats. Most recently he was a shore team member for Oracle Team USA at Core Composites, and oversaw the construction of Team Japan’s AC50.

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.

Scott BabbageScott Babbage

Scott has been a Moth class stalwart for the best part of 20 years, finishing 10 times in the top 10 at the World Championships. Scott and Riley met in the 18’ skiff, where Scott was a 5 x JJ Giltinan winner as sheet hand on board the highly successful 7 team.

Working as the Performance Coach for Softbank Team Japan in Bermuda, Scott was kept head down in data, figuring out how the AC50 worked and often liaising with Paul when analysing the performance of the Japanese boats.

Scott approached Paul, Riley and James to collaborate on the Bieker Moth project. Keen to take the Moth to the next level, Scott developed the broad concepts for the boat. Scott knows how to sail a Moth fast, and will be the test pilot, putting the boat through its paces.

Buying a Bieker Moth

The Bieker Moth will go into production in August. There will be 5 boats built in 2018, with the capability to produce 2 per month from January 2019.

The Bieker Moth will retail at $39000 NZD ex taxes for the platform, foils, fittings and ropes, trolley and covers.

Prices are subject to change, however all prices and options will be confirmed before the start of your build.

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

A build slot can be secured with a $1000 NZD deposit. Build slots are available on a first come, first served basis.

1 Year before your build slot commences we will contact you to finalise your decision to secure a build slot. At this time your build slot deposit of $1000 NZD is no longer refundable.

6 Months prior to your build slot start date a further non refundable deposit of $4000 NZD is required to continue to secure the build of your boat.

$5000 NZD is then credited toward the final invoice for the product.

30 Days prior to your build slot start date we will contact you to finalise your total invoice.

50% of that final invoice must be received by LSF Composites Limited 14 days prior to your build slot start date in order to start your build. If it is not received in that time LSF Composites Limited have the right to allocate your build slot to someone else and an alternative build slot will be allocated for you.

The balance of your invoice is due on or before your shipping date.
