Setting records for years

The world’s leading high-performance catamaran.
The most successful F18 catamaran.
A true blast to sail.

Overview

The Nacra F18 range has been dominating the racing circuit for decades. With this latest iteration of the record breaking F18 Infusion, the MKIII, we’ve turned it up a notch.
The Infusion MKIII design is suitable for an incredibly wide range of weather conditions, making competitive catamaran sailing an accessible treat for both experienced as well as new sailors.
And since 2021 the MKIII comes with an open multi-functional centerboard, designed to turn a best-in-class F18 into a fully foiling monster in less than 30 minutes 1.

THE BENCHMARK OF BOX RULES RACING

The Nacra F18 Infusion is a real racer, the hull volume is larger than other F18’s, which means higher speeds and rapid and precise boat handling. The wave piercing technology reduces drag and improves speed in all conditions. Whether you’re driving in big seas and big winds or gliding on a flat lake, the Infusion is a winner. In contrast to other designs, the Nacra Infusion MKIII stabilizes herself at high speed due to dynamic lift, hence reducing pitching to low levels yielding a far more consistent airflow over the sails, leading to those higher speeds. When you

are an MKIII owner, you don’t need to add anything, it’s all there. The fully battened jib, the self-tacking jib rail, the large spinnaker chute and the Harken™ Cunningham downhaul system which enables total mainsail control. Get high upwind with the high aspect daggerboards, responsive and positive rudders, a tightened trampoline from all four sides giving a firmer, drier, cleaner spacious platform. The sophistication of Performance Sails and the wind mast shape complement each other perfectly to allow you to improve your results.

Features

“If you want to be in front of the fleet, get an Infusion.” The Nacra F18 Infusion MKIII gets its name from the modern infusion construction system – this allows better material weight distribution within the hulls, yielding greater stiffness where it is needed, and stiffness is speed. Hull volume, larger than other F18s, means that the F18 Infusion MKIII drives hard with handling that is rapid and precise. Wave piercing technology reduces drag and improves speed in all conditions, the Infusion MKIII wins in big seas and big winds just as well as gliding on a lake in flat water. In contrast to other designs, the Nacra Infusion MKIII stabilises herself at high speed due to dynamic lift, hence reducing pitching to low levels yielding a far more consistent airflow over the sails leading to higher speeds. And it shows, as the F18 Infusion has won more races than any other F18 on the market.

This boat is a real winner, it became World Champion in 2008, 2009, 2013, 2014 and 2015 in the F18 class.
In 2019, Nacra Sailing released the Infusion’s successor – the Nacra F18 Evolution.

The fully battened jib, the self tacking jib rail, the large spinnaker chute, the Harken® Cunningham downhaul system enables total mainsail control, ask your dealer for the options. The high aspect daggerboards get you high upwind, the rudders are responsive and positive, trampoline is tightened from all four sides giving a firmer, drier, cleaner spacious platform. The sophistication of Performance Sails and the wing mast shape complement each other perfectly to allow you to improve your results.

ON SELECTED MODELS

All models outfitted with an Foiling Package (FCS or Flight Control System for short) are ready for full foiling – during your sail, specialized hydrodynamic daggerboards combined with upwards pressure make you get a controlled ‘flight’, meaning your whole boat will be above the water, rather than in it. Make alterations on the water during your flight to find the groove you are looking for and fly over water to leave others behind.

These so-called Foil sets are designed to fly in a wide range of weather conditions, to make competitive catamaran sailing accessible to even more sailors, and are built to meet the highest safety standards. A real treat for the more, or a little less, experienced sailors.

Using the best possible manufacturing techniques available, we’ve obtained maximum strength with minimum weight using autoclave technology, curing the pre-impregnated carbon/epoxy at 120 degrees Celsius at an atmospheric pressure of 6 bar. It will put you miles ahead of any fleet in terms of performance and joy.

IF18CA

The F18 class is founded in 1993 by Pierre Charles Barraud and Olivier Bovyn. The F18 class aims to provide fair racing for crews of various weights. With the use of two different sail sizes of jibs and spinnakers, crews can weigh from 115 to over 150 kg. Competition between the manufacturers keep the costs at the lowest level. Allowing mixed and female crews to compete on an equal basis in large male fleets made entering in the class more accessible for every sailor. The Formula 18 class keeps offering popular, exciting, safe and fair racing, and also keeps on growing and evolving.
