Nacra F18 Infusion
The Nacra F18 Infusion was announced in 2006 and launched in January 2007 as a one design racing catamaran conforming to the Formula 18 class rules. It quickly developed into a class in its own right.
The principal design team was Morrelli & Melvin but also included significant input from Peter Vink and Gunnar Larsen.
The design takes its name from the vacuum infusion process used in its hull construction.
The Nacra F18 Infusion has been a recognized World Sailing as an international competition class since November 2010.
The Nacra F18 Infusion design was later developed into the F18 Evolution and the NACRA F20 Carbon.
Design
The Nacra F18 Infusion is a racing sailboat, built to the Formula 18 Class Rules and its own One Design construction manual. These rules dictate that it is a fractional sloop rig with aluminum spars. The boat has a sandwich construction with fibreglass skins made using vinylester resin over a foam core. The Mk3 version uses epoxy resin rather than vinylester resin which, due to revised Formula 18 class rules, is permitted to use.Variants
The Nacra infusion is the third generation of Nacra Formula 18. It started in 1996 with the launch of the Nacra Inter 18 designed by Gino Morrelli and Pete Melvin. This was followed in 2001 by the Nacra Inter 18 designed by Alain Comyn.;Nacra F18 Infusion Mk1
