G-Force Yachts Racer Employs Diab Core Material

The X-Treme 32, the new all-round racer from G-Force Yachts, was built using Diab’s Divinycell HM core materials and the engineering expertise of Composites Consulting Group (CCG).

Headquartered in the Netherlands, G-Force Yachts manufactures high-performance monohulls.

“Each boat we build, whether it is an X-Treme 26, X-Treme 32 or X-Treme 37, reflects our passion and our pride for what we do,” says Founder and CEO Jeroen Wats.

At age 15 Wats knew that he wanted to build and develop high-performance racing yachts and after winning the Cape to Rio Ocean Race in 20 days in 2003, he decided to found G-Force Yachts and build a faster boat. The first G-Force Yachts vessel, the X-Treme 37, was designed by Reichel/Pugh Yacht Design and in 2006 the relatively small boat won the Cape to Rio Ocean Race in just 16 days. The new X-Treme 32, also designed by Reichel/Pugh Yacht Design, is expected to complete the same race in 12 days.

With the X-Treme 32, G-Force Yachts has aimed to manufacture a top-quality offshore racer while keeping handicap systems in mind. The handicaps change frequently and can reduce a racer’s lifespan. That is why Wats decided to focus on ultimate thrills and performance, and shaving the TCC/GPH down afterwards instead. The new all-around racer has a TCC of 1.164 and a GPH of 520.3 and is said to demonstrate speeds never before experienced in a fixed keel monohull.

In order to go faster, the X-Treme 32 required a substantial weight reduction. The helm is made of carbon fibre prepreg with an epoxy foam core while the mast and boom are also carbon fibre. The use of Diab’s lightweight Divinycell HM core material is reported to have provided a number of benefits, including high specific shear strength, higher resistance to denting and delamination from local impacts versus other foam cores, and the possibility of holding thinner laminates.

Divinycell HM is a high performance structural core designed for demanding applications such as fast marine hulls. Divinycell HM is an extremely tough product, capable of absorbing high dynamic impacts and slamming loads. Its elongation exceeds the requirements of ISO 12215, GL and ABS rules to allow for reduced safety factors in structural calculations, providing a lighter, yet strong structure. Its high compressive properties provide excellent resistance to denting and skin wrinkling of thin skins.

Benefitting from the engineering expertise of Diab Group company CCG, based in Australia, and the moulding skills of the Spanish company Xuquer, the X-Treme 32 has been designed to sail fast, reducing the wetted surface to a minimum in the event of the boat listing slightly and to increase its stability if it does.
