Huntsman Advanced Materials (The Woodlands, Texas, USA) reported on Aug. 11 that its tooling and production materials were selected to construct a new One Design carbon racing yacht. The CODE8 is a light displacement, high-performance racing yacht. Designed by America’s Cup yacht designer Andrej Justin and manufactured by Carbon Innovation Ltd.

CAD data was initially used to produce a plug of the yacht from a PSFoam substructure and (RenPaste SV36/Ren HV 36) modelling paste. The parts were then CNC machine milled to create a master model for fast extrusion, exhibiting both low shrinkage and a smooth surface finish.

A high-performance gel coat (Resin XD4615/Ren HY 5159) was then applied to the master model and a backing layer was built up (using Renlam CY219/XB5173 in combination with glass fiber) to form the mold for the hull, deck and all other parts.

The hull and deck have been produced from the mold using a hot curing system for vacuum infusion (Araldite LY 1564/Aradur 2954) and bonded together with an epoxy adhesive (Araldite 2015) which forms durable, elastomeric joints that are water tight and weather resistant.

Combining low viscosity with a long pot life at elevated temperatures, the hot curing system offers good mechanical, dynamic and thermal properties. Optimised to provide high Tg, this high-temperature-resistant system is also said to be suitable for the manufacture of boats finished in dark colors, such as black or dark blue.

For other components, including the mast and rudder, an Araldite prepreg system (Araldite LY 1556/Aradur 1573/Accelerator 1571/Hardener XB 3403) was selected and used in combination with Carbon Innovation’s self-developed prepreg machine.

Progress through the design, development and production stages was rapid, with the first CODE8 yacht completed in just four months. The boat will first take to the water to compete in the Keszhely-Kenese, a short handed solo race, on Aug. 20, followed by two races in September and one in October in Spain.
