EPDs signal a manufacturer's commitment to measuring and reducing the environmental impact of its products and services and report these impacts in a hyper-transparent way. With an EPD, manufacturers report comparable, objective and third-party verified data that show the good, the bad and the evil about the environmental performance of their products and services.

When developing an EPD, the environmental performance of the product shall be described from a life cycle perspective by carrying out a life cycle assessment (LCA) of the product. The results of the LCA study and other information mandated by the reference PCR and General Programme Instructions shall be compiled in the EPD reporting format. The EPD shall then be verified by an approved independent verifier before being registered and published at the International EPD System via our EPD Portal.

The IMOCA measurement 2025 rule favours the use of alternative materials for removable elements of the boat (chart table, seats, bunks, holds, etc.) which will be removed from the rule weight of the boat up to a limit of 100 kilos. This was already the case for solar panels, green energy systems and scientific instruments.

AG.0 Definition:

Alternative material: Material elaborated from natural material or fiber (organic or mineral), and/or recycled material intended to be used alone or in mixture with bio-based thermosetting matrices >30% or thermoplastic matrices (see list of alternative fibers, matrices and cores).

Recycled material: material of which at least 80% by weight of the raw material comes from a process of reprocessing and/or transformation of materials from finished products.

The Floki 6.50, designed and built by Antoine Mainfray, uses Cobratex bamboo sandwich material as it's principal composite, recycled PET core and Sicomin bioresin.

This report by Team 11th Hour Racing on their 2021 IMOCA build includes

• A review of the current situation

• Research into new sustainable design and build opportunities, with support from Kairos

• Short term practical recommendations

• Cradle to gate life cycle assessment using MarineShift360

• Long term recommendations

The report Sustainable Design and Build Report is available in English and French.

The Arkema IV Ocean 50, launched in September 2021 uses the Elium thermoplastic resin for a number of components including the crossbeam mold, which was recycled at the end of construction.

Pip Hare completed the 2020 Vendee Globe with OneSails 4 T Certified recylable sails. For the Vendee Globe 2024 all IMOCA's must include a 'Greensail' amongst the 8 that they are allowed such as the Onesails 4T.

Foiling SuMoth Competition, Foiling Week

The Foiling SuMoth Challenge was created by Foiling Week™ — the first and only global event dedicated to the amazingly fast foiling boats, their sailors, designers, and builders — to support and promote sustainable boat building practices. This unique design competition challenges students to construct competitive Moth class compliant foilers while also considering the environmental, social, and economic impacts of the manufacturing process.

The Baltic Café Racer uses flax fibre for more than 50% of its hull and sustainably sourced cork for the decking. She also has an electric propulsion system, hydrogenerators and improved energy efficiency for hotel systems.

The majority of the hull is made of BComp's ampliTex™ natural flax fibre reinforcements, rather than carbon- or glass fibres. Consequently, the environmental impact is dramatically reduced as flax fibres are a naturally grown, CO2e neutral raw material. At end of life, the natural fibre composites can be incinerated and used for heat recovery, without residual waste. Thanks to Bcomp’s ampliTex™ technology delivering superior sound deadening properties, the use of insulation can be limited, and weight further reduced. Furthermore, the fibres naturally have around 3 times higher vibration damping, making them attractive for boat building.

The Loop Mini 650 "Amável" was built using enriched basalt fiber and bio-based resin to demonstrate that full recyclability and sustainability could be associated with high end performances, Specifically, enriched basalt allows for full reclaim of raw material to be re-transformed in new virgin fiber with no downgrade of performances at End of Life, and recyclamine allows the reclaim of bio-based epoxy resin from cured composites to be re-proposed as thermoplastic for injection moulding applications. . Recyclable sails are in 4T from OneSails.

The full cradle to cradle recyclability of the reinforcement was verified in ENEA (Italian National Agency for New Technologies, Energy and Sustainable Economic Development), paving the way for further investigations in order to take the solution to high volume industrial sectors. The EU Funded C2CC project validated this solution for automotive manufacturing as for the original vision. The Loop Mini 650 was supported by Regione Lombardia and a number of technical partners sharing the vision for circularity including Amer Yachts who is now taking the vision to production of their line of FRP Super Yachts with an ambitious program to replace fiberglass with sustainable composites.

GS4C recently supplied sustainable parts to BIOTHERM as for IMOCA's rule on alternative materials.

Northern Lights Composites, Ecoracer 25

Multi award winning, the Ecoracer uses rComposite, an innovative composite based on a thermoplastic matric, natural or mineral fibres and Atlas HPE recyclable core. rComposite was developed by nlcomp in 2020 and is patent pending. (nl composites, 2022).

Based on more than 10 years of research & development. The Flax27 is made from 80% natural and/or recycled materials. At 1,200 kg, it is more than 10% lighter than a comparable GRP construction. Learn more here.

The skipper Armel Tripon set off on the Vendée Globe with a seat made from low-cost biosourced carbon fibres, the first piece of equipment produced by the IRT Jules Verne as part of the Force project. Read more here.
