The MIMOCA 120: a miniature racing sailboat

Today, Pierre-Edouard Regaud presents his miniature version of the IMOCA Hugo Boss, which finished second in the 2017 Vendée Globe—renamed for the occasion: the MIMOCA 120.

This small sailboat was made possible thanks to the use of E-glass twill fabric 204 g/m², HR 3K carbon twill fabric 193 g/m², and the epoxy resin kit SR 1700 / SD 2805 from SICOMIN.

To build his miniature sailboat, Pierre-Edouard Regaud first had to create a master that would serve as a plug to later produce the final mold. He chose to use 204 g/m² twill fiberglass fabric along with epoxy gel coat SG 715 to reinforce the master.

Once the mold was ready, he carried out a vacuum infusion of the carbon fabric using SR 1700 resin. This process allowed him to combine lightness and strength in his scale model.

He also decided to use 45° HR carbon sleeves to manufacture the carbon mast.

To ensure flotation and increase speed, he used two carbon foils, which were oven-cured to improve the stiffness of both parts.

Some components were placed in an oven to increase their rigidity—this is the case for two profiled carbon wings called foils. Positioned on the sides of the sailboat, these wings generate lift, which directly affects the boat’s speed and stability.
