Materials and Construction
The masts are layed-up - layer for layer - with a combination of different stiffness carbon fibres.
While most of each mast is manufactured using industry standard T-700 grade fibres, the localised stiffeners can only perform as required by using a higher grade (M40J) fibre. Further strength is added by use of woven cloths which are orientated to reduce the influence on the stiffness of the mast.
The dynamic response of the mast is carefully controlled by the combined use of the fibres at specific points in the section. This results in being able to regulate the amount of twist in the mast while sailing.
All the masts are cured under identical conditions with an internal pressure bag system at 3,5 bar in the custom built oven set to 120°C.
All HIT masts a customized for the helmsman. Weight and sailing experience is a major issue when customizing the mast for speed and sail handling.
We recommend North Sails for HIT masts.
How to measure your mast curve
Support the mast with the tip at a height which will allow the tip of the mast not to hit the ground when the weight is placed on it. Fix in place at the butt to allow to rest on the collar as it holds by the mast step and deck of the boat. Mark the point A. See picture below.
Place the weight (12 kg Sideways / Fore & Aft) on the tip of the mast at the measurement band. Mark the point B for sideways and fore&aft.
Take a taught string from the top of the bottom measurement band (D) to the bottom of the top one (C).
Measure the distance in millimeters between the string and the mast (Sideways and Fore&Aft) in every 1/4 of the distance CD.
