Geez
With the rate of development, the classes we grew up sailing seem ancient
Think Sabres, 125's, fireballs, 505's, J24's, whatever your club had
They're history, or are they?
Maybe not everyone can afford to sail such radical boats,I can't, but hanging on the wire of a five o still brings back great memories
Maybe these filers will be mainstream in a few more years, or are they already?

Yes sorta great, but was hobby horsing with what seemed likely to bury the bow.
Would like to see another foil about 800mm back from the pointy end, just to help stop
the nose dive and cartwheel,........... but i'm drooling anyway....if a bloke were 20ish again.... ho, hum

Specs
The boat is not just a modified F18 but it is entirely designed to foil, the only common part is the shape of the hulls.
Lenght: 5,52m / 18"
Width: 3,00m
Mast: 9,5m / Carbon autoclaved
Weight: 150kg
Hulls construction: PVC sandwich, carbon fiber, epoxy
Main area: 18sqm with mast
Jib area: 5sqm
Gennaker area: 24sqm

Speed against other racing boats
As soon as you have enough wind to fly a hull in 6 knots of True Wind Speed, the boat is faster upwind and downwind than an F18, the boat takes off downwind at 10 knots of TWS and then is much faster than most of the beach cats. We did some speed testing against a Vampire Marstrom 20 (3,5m wide) and the Phantom is faster downwind as soon as it foils and very similar upwind in 15knots of TWS.

Max Speed
We have actually reached 27 knots in 18 knots of TWS without kite and no one trapezing , we are actually working to improve the control of the steering which is clearly the limit to go faster. We believe we could achieve between 30 and 35 knots while we will have improved the stability of the boat.

Goal of the project and production alternatives
The target is to be able to produce a real production boat for next year, we are still doing some development on the foils and we try to make the systems as simple as possible in order to get a boat usable by most of the club sailors. We believe the new generation of foiling cats could attract more people to cat sailing, like the parabolic ski did 10 years ago. All sailors who sailed the boat are extremely enthusiastic, flying above the water brings incredible new sensations and although not requiring any specific skills.

Costs
The target price is to be only slightly more expensive than an F18 by having a fully industrialized product and selling direct. We hope the boat will be around 25 000 Euros ex tax.
