The new Yamarin Cross concept boat has been launched. The boat is developed in collaboration with Finnish based Inhan Tehtaat, manufacturer of Cross boats, and EKA Composites.
The boat, currently on show at the Vene 25 Båt Helsinki International Boat Show, is based on the Yamarin Cross 62 BR model and uses recycled aluminium, linen fibres, and plastic from recycled bottles.
The reinforced plastic deck structures of the Yamarin Cross 62 BR concept boat are manufactured by EKA Composites’ facilities. The aluminium hull – which contains between 30 – 70% recycled material – is manufactured by Inha.
The new materials and production methods are being researched as part of development work being carried out by Yamaha Motor Group with the aim of transitioning to carbon-neutral production in its factories by 2035.
“Together with EKA Composites, we want to show that natural fibres and recycled materials can be used in boatbuilding not only economically but also to build a very stylish boat,” explained Artturi Niittynen, sales and marketing director at Inha Tehtaate.
As a natural material, flax has not yet been used in the series production of boats, but it has the potential to partially or completely replace fiberglass.

“New materials will be tested in usage and durability tests during the upcoming boating season, and a decision on a commercial launch will be made based on the tests and market feedback.”
The companies involved believe the new materials will save weight and CO2 emissions with no reduction in durability and strength.
“As a natural material, flax has not yet been used in the series production of boats, but it has the potential to partially or completely replace fiberglass,” says Henna Forsström, responsible for procurement at EKA Composites.
“The long fibres, up to 90cm long, give the material mechanical durability, which makes it suitable for applications requiring strength.”
Concept boat
In addition, the concept boat is also testing a new resin as a binder and gelcoat.
The new Maxguard NP gelcoat, is said to reduce volatile organic compound (VOC) emissions by up to 50% and 10–15% material savings.
“The new gelcoat also has the advantages of a very hard, stylish-looking surface, as well as UV resistance and excellent blistering resistance, which are important in marine conditions,” explained Henna.
The production of the deck of the Cross 62 BR concept boat is part of the ‘Green transition of vacuum infusion process’ project, for which EKA Composites has received support from the Finnish Centre for Economic Development, Transport and the Environment.
The project is co-financed with EU support.
