Reverse engineering: For the general refurbishment of an original German Frers sailing yacht, Scheurer Swis reconstructs and produces customised replacement components made of chrome steel.

Sailboat Blink: Reverse engineering spare parts from chrome steel

The customised chrome steel replacement components from Scheurer Swiss

As a specialist in the field of fibre composite technology, Scheurer Swiss GmbH develops and produces ultra-light and extremely stable composite components made of carbon fibre reinforced plastic. With over thirty years of experience in engineering, it is also an expert in reverse engineering, even outside the field of lightweight construction. For the restored daysailer “Blink” from “German Frers”, she recently reconstructed a massive chrome steel bow fitting, including water stay and stern fitting, with millimetre precision.

Elaborate renovation of a German Frers prototype

As one of the fastest sailing boats, the “Blink” took second place in the “Racer 1” category at the fifty-first regatta of the “50-Mile Trophy” on the famous Lake Lucerne on 25 June. She was designed by the well-known and successful yacht design and construction office, “German Frers”. Hundreds of successful yacht designs for European, American, Japanese, Australian and New Zealand clients have come from the Frers yacht design dynasty. The “Blink” boat owners, Daniel Gut and Alex Seiler, brought the French-based sports boat to Switzerland and extensively refurbished it. This included the urgently needed reconstruction of the fittings for the bow and stern as well as the corresponding water stay. The successful boat-owning duo engaged the engineering company “Scheurer Swiss”, known for its many years of expertise, to develop and produce these replacement parts.

Reversing the development process

Normally, a component is created on the computer by designing it with special drawing software, the so-called Computer Aided Design (CAD), in such a way that its production becomes possible. Whereas in engineering, components are designed and assembled to create a functional end product, reverse engineering reverses this process. It describes the process of extracting the design elements from an existing finished system or a mostly industrially manufactured product by examining the structures, states and behaviour and reconstructing them in CAD. The development and production process is thus reversed, and a plan is created again from the finished object. This is exactly the procedure Scheurer Swiss used to reconstruct the customised replacement components for the “Blink”.

From the boat plans back to the construction drawing

In order to design the chrome steel fittings for the bow and stern as well as the water stay for the sailing yacht, the experienced engineer and owner of Scheurer Swiss GmbH meticulously analysed twenty-two of the more than sixty existing boat plans of the “Blink”. Together with a hand-drawn sketch made by the two boat owners, he was able to determine the necessary dimensions, contours and angles he needed to reconstruct the components in CAD.

From the existing boat plans and a hand sketch of the requirements, the new construction plan for the spare parts of the “Blink” is created in CAD.

“The challenge was to filter out the right information from this multitude of plans and data and transfer it to the new CAD model in such a way that everything fit together again in the end,” emphasises Dominik Scheurer, CEO of Scheurer Swiss. An alternative to the viewing of the boat plans is a so-called 3D scan of the bow. “However, this procedure is more expensive compared to the manual creation of the CAD data,” Scheurer accentuates.

Thanks to clever engineering, Scheurer Swiss GmbH develops pioneering solution with unique composite carbon 3D print components for a high-tech sailing catamaran.

Exploring turquoise waters in style and peace on board a luxurious high-tech sailing catamaran or crossing oceans on a fast pace – this is what Moonwave Gunboat 60/03 with its hybrid system offers its owner and his guests. The carbon fibre catamaran is taken care off by two competent and friendly crew members who keep it up to date and also at the edge of technology.

Thanks to clever engineering, Scheurer Swiss GmbH develops unique composite 3D printed carbon components for high-tech sailing catamaran.

Thanks to clever engineering, Scheurer Swiss GmbH develops unique composite 3D printed carbon components for high-tech sailing catamaran.

The Moonwave crew recently ordered highly modern and extremely efficient carbon-reinforced 3D-printed composite components from Scheurer Swiss GmbH. It was only thanks to sophisticated engineering and a unique bonding mechanism that it became possible to develop composite carbon 3D print components of the required dimensions. The parts will be fitted in a state-of-the-art titanium rudder bearing system – for this application precision, weight and strength are key factors. With diameters of up to 630 mm, an impressive size for two 3D-printed components, the bearing cages will be an essential feature of making the steering of the luxury catamaran even easier.

Your project in good hands

With the right engineering, the innovative technology of composite carbon 3D print finds the most incredible areas of application – we will be happy to advise you on your journey to an ultra-light, extremely stable future!
