Firefly is the prototype of a new one-design race-classic of the F-class. She is developed as a high-performance racer, optimised to race in the Spirit of Tradition class. The design brief called “for a yacht to be fast on all points of sail, both in light- and heavy wind”. With a displacement of just below 60 ton and a draft of 5,2 meter, the design is extremely powerful. The one-design class that is developed under the auspiciën of the F-Class Association also allows a lifting keel to be used, but the first prototype will be built with a fixed keel.
On Wednesday April 21st 2010, the two carbon fibre masts of giant schooner Athos were stepped and supplied with SmartRigging PBO. The event took place in the early morning at Holland Jachtbouw in Zaandam, just above Amsterdam/Netherlands. By the end of the afternoon, the 203ft privately owned cruising yacht, designed by Andre Hoek, was ready for the first trimming session.
“We designed the standing rigging for Athos, which is all custom made”, explains Constantijn Weber from Joure (Netherlands) based SmartRigging. “Rod rigging is the standard for this segment. However, we supplied her with lightweight composite rigging, normally used for racing yachts. It is approximately eighty percent lighter than stainless steel, which makes it interesting for a 62 meter long schooner as Athos.”
Weber about the process: “We use a high quality production technique, called endless winding, optimized by us. It allows us to work very precisely. We put the same amount of tension on all fibres to stretch them equally, which results in low stretch and a long life span.”
Designing the standing rigging for 203ft Athos was not a usual challenge for SmartRigging. Weber: “No, the biggest yacht we have done before was 32 meter long. The engineering work took up most of the time, as everything needs to fit at once. We can’t make any mistakes, because that means you can start all over again. It is impossible to adjust the rigging length as soon as it is produced.” Walking onboard of the Dutch schooner he smiles: “Fortunately, we succeeded.”
Athos & SmartRigging in facts
Athos is the largest two-mast schooner ever built. She is designed by Andre Hoek and built by Holland Jachtbouw. The carbon masts are manufactured by Rondal and the standing rigging by SmartRigging. She carries the biggest lightweight rigging package yet supplied in the world. Compared to rod rigging, it saves the weight of four Mini Cooper cars at the height of the first spreader. A total of 5.500 kilometres of fibre has been used for the standing rigging.

Congratulations, Team BMWORACLE, with a perfect score !
After a long period and hard work from both teams, it is safe to say that it has been an epic battle.
Allthough the result is very clear.
A great effort and some solid “out of the box” thinking on BMWO team brought them the victory.
What a spectacular piece of machinery !
