saying a mach 2 can win a worlds out the box is totally misleading.  Although it's great for re-sale value!  But seriously, has anyone ever won without doing a lot of work on the foils first?
Nowadays you need to do a ton of extra stuff like getting a kinked boom, a bowsprit, a telescopic adjustable wand that doesn't make you illegal when you shorten it etc etc etc.  And then it's still harder to tack anyway.  Most people who get an exocet after a mach 2 can't believe the difference.  In big waves I've heard one guy say that going down wind is like being in an arm chair.  the only reason mach 2 sales aren't dead is because of the exocet wait.
People getting them now ordered them at the prizegiving at the worlds.  The Hayling worlds!  And as the guys above say the list ain't getting shorter and the results from this week show why.


Thoughts on production volume affecting the end product? I wonder what a Mach2 would look like/how fast it would be if they were selling 10 per year... AMAC does seem to have a completely different philosophy about design.

Yes. He is very good at designing for manufacturing at scale.

So it looks like the smarter option is to buy a rocket. Obvs. quick but a shorter wait to get one ?

For me it's surprising that none of the Mach2s seem to have bowsprits.


I guess most of the mach2s from the ac teams which didnt'do the 2016 worlds are basically the same as sorrento (outerridge, oracle boat used by goto, etc).
I've been told bowsprit will come as standard on m2s next year along with new rudder, sail and tramps, but it's just chat,so not really sure. I guess amac is really trying something new before garda,now that the waszp is up and running.

That is one of the big differences with the Exocets. You are always getting the latest gear when you buy one, you don't have to wait until the next "version" is released. An Exocet can, in theory, win a worlds "out of the box", a Mach 2 can't anymore.

Phil ... I call bullshit the :

RS 700

RS 800

RS 900

RS Aero

RS Elite

 

Are all unique boats, each adding value to our sport, and they do nothing to dilute fleets. :wacko:

 

By contrast, when you have multiple manufacturers building within multi-design classes e.g. A Class or NS14, the competition for sailors business actually benefits the fleet numbers.

So the foiling 101 is the latest in a long line of one design foilers trying to be the next laser.
 
Some feel that they need to take to bashing the moth class as a way to sell boats. Sell your product on it's own merits and stop making up lies. For example ... the pitch control claim with a foil based wand. It makes construction easier, but it makes the boat worse from the point of view of pitch control. 

 
Wrong, dead wrong.  Wands that sense altitude near the CG of the boat are used on the Rave, Osprey, Skat, and Whisper , Laser and F101. There is no chance of pitch coupling with altitude in such an arrangement .
 
The specs have been updated to reflect length and beam:
 
DESIGN

  • Long central hull gets the rudder and main foil further apart, removing some of the limitations and bad habits that other foiling boats suffer from.

  • All carbon construction: main hull, foils, floats, beams, 2 piece mast.

  • Very simple, well thought out control systems.

  • All up weight: 80 kg

  • Length 5m

  • Beam 2.55m

  • Sail area: 8.5m2 main + 7m2 gennaker

  • Target crew weight range: 70-120 kg

  • Take off wind speed: 8kts

  • Target boat speed range: 10-25kts



SO WHY THREE HULLS?
Many Moths use buoyancy in the wings to help sailors get to grips with the boat, but this buoyancy is limited to helping the helm recover the boat from a capsize and does nothing to prevent the capsize in the first place. The F101 Tri configuration allows for a slender hull with enough length to prevent pitch poling, while at the same time creating a stable platform to allow novices to get out on the water with no previous foiling experience. The super slender wave-piercing outer hulls are set at an optimum angle to initiate foiling - simply sit on the windward hull, which will cant the boat to windward, then sheet in and take off! If the F101 does pitch forward, the main hull is designed to recover straight back onto the foils; the hulls additional length keeps the angle of incidence shallow. Its rocker is matched to the angle of incidence and the additional buoyancy forwards help lift the bow. The benefit applies to the outer hulls too - if the F101 falls in to windward, the windward hull lifts the boat back onto the foils. If the boat falls in to leeward there is enough buoyancy to prevent a capsize and the boat is quickly back on the foils.

 
 
WHY IS THE WAND ON THE TRAILING EDGE OF THE MAIN FOIL?

 


 The F101 has its control wand fixed to the back of the trailing edge of the main foil, as opposed to the mounted at the bow which is where Moths mount  the foil. There are a number of advantages to the trailing edge position, the most important of which is that the wand measures the ride height of the boat irrespective of pitch. This important factor can help to eliminate the porpoise effect which many beginners experience when learning to sail a Moth. 
 
 


Oh sorry Doug. You read it on the internet so it must be true. My apologies.
