Marlow Blue Ocean Logo

Marlow bring together all their eco-conscious development under one BLUE OCEAN® brand.

Marlow BLUE OCEAN® reduces the reliance on fossil fuels by using fibres manufactured from either waste plastic or natural sources for yachting and boating.

The Marlow BLUE OCEAN® brand is their mark of sustainability assurance and on-going commitment to conduct all operations within an environmentally conscious framework.


Marlow BLUE OCEAN® yarn is GRS certified and manufactured from 100% recycled waste plastic bottles collected from disposal units.

The bottles are manufactured into recycled polyester (rPET) to produce a yarn which has the same specifications and technical characteristics as polyester yarn manufactured using virgin feedstock.

BLUE OCEAN® yarn can be recycled again at the end of its life, therefore aiding a circular economy, as long as it has not been mixed with any other chemicals or fibre materials.
