In Formula 18 racing, all producers have to try to top of the racing results and therefore on top of the market. All sailors know that Formula 18’s are innovative racing machines and therefore will continue to change to meet the demands of the market.The Nacra Infusion is made with the latest production technology and hull design by a company famed for quality production. The Nacra Infusion is the most innovative sports catamaran on the World market.
The Nacra Infusion is the only production catamaran that is made with infusion technology. This technique makes sure that weigh distribution in manufacture produces a much stiffer hull compared to conventional methods, and stiffness of hull produces extra performance in high level racing for many more years.
The production of dagger boards and rudder blades is also new, being made in three dimentional shaped aluminium moulds using high compression to give Nacra F18 Infusion stiffer and stronger blades for high level racing. These are the same techniques as used to build the Nacra A2, World Champion A-Class in 2005.
The Nacra Infusion features a wing mast that provides superb rig dynamics coupled with advanced sail design from Performance Sails.
Wave piercing technology is the way forward as the Nacra A2 has proved, and the Nacra Infusion developes this technique. Compared to conventional hull shapes, wave piercing hulls gives less water resistance hence more energy that can be turned into boat speed, especially upwind where the boat pitches less than other traditional F18’s hence sailing significantly quicker. In light conditions the boat is wave piercing but as the wind increases the crew weight is moved further aft and the boat starts to plane upwind !! In contrast to classic designs, the Nacra F18 Infusion stabilises itself at higher speeds due to dynamic lift, hence reducing pitching to low levels, which means that there is a more consistent airflow over the sails and rig which is translated into more boat speed.
