Ocean-Offshore Sails

Uncompromising performance, durability and reliability

OneSails develops a wide range of products for ocean and offshore sailing. These sails are produced with specifications, yarns layers, finishing and details expressly developed for use in extreme conditions both for racing and cruising.
Offshore performance sails are produced using 4T FORTE™ composite technology that have been successfully tested on racing and cruising yachts sailing rood the world. It offers an unbeatable strength/weight ratio with sails up to 25% lighter compared to other technologies and this allows the production of reliable and long lasting sails without compromising performance.


OneSails’ 4T FORTE sails have been used in offshore transoceanic races since a few years now, we have completed a few Vendée Globe,Transat Jacques Vabre, Route du Rhum, Mini Transat and Sydney-Hobart with success.

How the IMOCA 60 sails are made

John Parker from OneSails GBR East explains how the reliable OneSails IMOCA sails are made.

Gentoo Sailing team

Skippered by young British sailor James Harayda, he made her debut in the IMOCA class in 2022 after a career in the DH offshore championship. By qualifying for the Vendee Globe 2024, his first participation, he will be one of the youngest skippers to cross the starting line.


After an experience with the Mini-Transat and Class40 he then moved up to the IMOCA class and competed in the 2016 Vendée Globe. He became the 1st sailor to complete the race with 0 emissions. A challenge he is keen to take up again in 2024.

Pip Hare Ocean Racing

On her first attempt at the Vendée Globe, despite racing the oldest centreboarder of the fleet and suffering the rudder blade replacement pit stop, Pip Hare finished brilliantly in 19th position (2nd in the women’s ranking) challenging the performance of the foilers.

Ari Huusela

The goal for the Finnish sailor was to finish the Vendée Globe with no faults and he successfully accomplished his mission thanks to conservative racing tactics and to a super reliable boat and sail set. .
