Nacra F18 Evolution

Press Release Nacra F18 Evolution:

"The Nacra Sailing F18 Evolution revealed; a racing catamaran representing a unique design combination of 45 years of experience with advanced technology and sophisticated design tools

Nacra Sailing has chosen to replace the renowned Nacra F18 Infusion with the newly developed Nacra F18 Evolution on Nacra’s 45th anniversary.

Nacra Sailing teamed up again with their long-time development partner Morrelli & Melvin to set its goals in this ambitious project. Nacra Sailing and Morrelli & Melvin have a long history, having done many successful projects together such as the Nacra F18 Infusion which was launched in 2006. This successful relationship also includes the development of the Olympic Nacra 17 what has changed the face of sailing by becoming the first event in Olympic sailing to introduce hydrofoiling.

The design program of the new Nacra F18 Evolution started last year at the 2018 F18 World Championship in Sarasota, USA, when M&M Naval Architects Ferdinand van West (2 time F18 World Champion) and Pete Melvin (Olympic sailor) teamed up to sail the Nacra F18 Infusion. Together with Nacra Sailing owner and technical director Peter Vink’s coaching, the duo finished their first event in 6th place. Inspired by the experience, they brought back a wealth of data from the event which they applied directly to the drawing board.

The primary ambition of the new Formula 18 design was to build upon the Nacra F18 Infusion’s unique pedigree as the best all-around performing F18, over the full range of sailing conditions for every sailor.

The hydrodynamic characteristics of the Nacra F18 Evolution’s hull shape are completely revised and benefit from the latest design tools used by America’s Cup teams to analyse the performance of dozens of hull shape iterations in Computational Fluid Dynamics (CFD) simulations. Since their involvement in the last three America’s Cups, Morrelli & Melvin have invested in using NUMECA’s FINE/Marine CFD software for design optimization, utilizing high performance computing resources and advanced performance prediction simulators to add fidelity to race model analysis.

Most notable, the Nacra F18 Evolution’s hull shape design has an aggressively styled raked wave-piercing bow with a horizontal hull chine running back into the transom. This elegant solution cleverly distributes the volume and contour curvatures desired for each dynamic condition and delivers a unique compromise for both sailing upwind and downwind at different speeds. The optimized foredeck in front of the main beam and embedded beams into the hull add extra sleekness to this design.

There was a careful focus on the platform configuration, which features an updated longitudinal beam position to optimize the hydrodynamic and aerodynamic balance between the sailplan and the appendages. This has been further enhanced by a new high aspect ratio rudder design, refining wetted area, and updates to the hydrofoil sectional shape to the latest developments.

Close collaboration with the aerodynamic sail design of Performance Sails has ensured an optimized sailplan which features the regatta proven deck sweeper mainsail and an optimized jib design tailored to the new mainsail.

The Nacra F18 Evolution will make its F18 worlds debut at the 2020 Formula 18 World Championship in Formia, Italy, and is available for order with first deliveries starting in February 2020.

The Nacra F18 Infusion will stay in production, as the only convertible Foiling Catamaran on the market that can be easily converted to a F18 class legal boat. "

A lot of Windrush in that hull shape.

Fucken oath there's still a few odd differences.

Would have flushed the decks with the top of the front beam and at least double-skinned the tramp on the front beam.

Also missing the nice foot-rest spot on the back of the rear beam the windrush has.

Doesn’t look as good as a Windrush though and I would put money on it, it is not built anywhere near the same standard as well.

To me it looks more like a scaled down F20c, with a bit of Windrush and Scorpion mixed in.

The front deck looks flush to the beam, aft no but that is a lot of extra weight for minimal gain, the Edge nor Scorpion nor Cirrus R2 do that.

The tramp could be double skinned just aft of the beam, but I think the gains there are very minimal as A-Class sailors have won races at the Worlds level without an under tramp and they are running speeds 25% higher. Wrap around tramps are okay, until you have to replace them then all the front beam hardware must come off!

I do like the new rudders, those should have been an option some time ago as the wide blades both Nacra and Goodall use are good at the start and in the corners but very sensitive to setup to get the helm to have proper feel.

I won't say that Nacra can match a limited production build by Windrush but the Mk. 3's and N17 Mk. 2's are pretty nice looking boats and stiff. Mk. 2's are still winning races globally so stiff enough imo and the epoxy Evolution will be too.

Sent a PM on that. IDK what the Evolution will cost, but you can get an idea on F18 pricing from these guys: https://www.h2o-sensations.com/en/nacra-catamaran/1276-nacra-f18-infusion-mkiii-2000000012766.html#/2366-boat_model-fcs

I have to say that now is a great time to get into the fleet, there are C2's and Infusion Mk. 2's available at excellent prices and they are competitive boats. Maybe not as fast as the latest but Robbie just won the NA's on a late model C2, there were 2 C2's in the Top 12 at Worlds and the Infusion Mk. 2 took 2nd at our recent NA's and remains competitive. We also had close racing with Capricorns and a Hobie Tiger held their own at the Nationals, so the good news is the older boats are still absolutely competitive. Crew practice matters more than platform until you are talking the top 20 or 30 boats at the Worlds where the latest designs have a small speed advantage over the older boats.

Pics up on facebook. Looks like they are using the Mk.3/N17 Mk. 1 rudders for now. Also looks like they went for a single line hoist system on the kite, which is surprising.

Very nice, and all that lovely metal to polish, and at a quarter ton, should be lovely and forgiving to sail.  Do they make a racing version too?

You might want to look up F18 class rules.

I'm sure he's very familiar with the class rules; F-18s are unnecessarily heavy.

This is the first full-size NACRA racer that doesn't look like a NACRA.

But, it's a pretty design.
