F-31r - Corsair 31

Description

The Corsair F-31R (also known as the F-31 Racing or RS variant) is a high-performance, trailerable folding trimaran designed by New Zealand naval architect Ian Farrier and produced by Corsair Marine International from 1991 to around 2000. It's an enhanced racing version of the standard F-31 Sport Cruiser, featuring a taller carbon fiber rig, bowsprit for an asymmetrical spinnaker, and lighter weight for superior speed and agility. Evolving from the custom F-9 prototype (launched 1991), the F-31R prioritizes one-design racing and adrenaline-fueled day sailing while retaining enough amenities for weekend cruising. With over 300 F-31 variants built, the R model stands out for its competitive edge, earning accolades like Australian Boat of the Year in 1992. Owners rave about its "effortless planning" in 10-15 knot winds, hitting 15-20+ knots routinely, but note it's best for skilled sailors due to its sensitivity in heavy air. Post-2000, Corsair evolved it into the Corsair 31 RS.

Custom sail calculations are not possible for this boat as no I, J, P and E dimensions are available.

Disclaimer. Boats are not all the same -- even when produced in the same factory of the same model. Sailrite does its best to publish accurate dimensions, but we often find it worthwhile to have our customers measure their boats carefully before we produce kits for them. You should take the same precautions, especially when the data is not from Sailrite.
