The design takes its name from the vacuum infusion process used in its hull construction.[3][4]

The Nacra F18 Infusion has been a recognized World Sailing international competition class since November 2010.[5]

The Nacra F18 Infusion design was later developed into the F18 Evolution and the NACRA F20 Carbon.[6][7]

Production

The design has been built by Nacra Sailing in the Netherlands since 2008 and remains in production.[8]

Design

The Nacra F18 Infusion is a racing sailboat, built predominantly of epoxy resin and vinylester fibreglass over a foam core. It has a fractional sloop rig with aluminum spars. The hulls have vertical transoms, transom-hung carbon fibre rudders controlled by a tiller and dual retractable carbon fibre daggerboards. It displaces 396 lb (180 kg), uses twin crew trapezes and flies a nylon asymmetrical spinnaker of 226 sq ft (21.0 m2).[1][4]

Variants
Nacra F18 Infusion
This model was introduced in 2008. Its hulls have plumb stems and the rudders are a "kick-up" design.[1][3][4]
Nacra F18 Infusion FCS (Flight Control System)
This sailing hydrofoil model uses the same hulls as the Infusion, but adds "L"-shaped hydrofoil rudders and "Z"-shaped carbon fibre daggerboards.[1][3]
Nacra F18 Evolution
This model has the same specifications at the Infusion, but incorporates a new hull design with reverse raked stems, horizontal chines and a revised longitudinal connecting beam design. The rudders are a "kick-up" design.[1][6]
