AC35: Team New Zealand AC50 Cycling explained by Mike Drummond



Image: Team New Zealand press. - Time to ask the Pros about TNZ cycling systems benefits and there is few people more indicated to write about AC devels than Mike Drummond. If you still don´t know his cv, read it here as told by Coutts (One day I need to re publish that text, maybe the best presentation speech ever)
-------------------
Mike Drummond on Team New Zealand cycling system and previous similar developments:
"It's a good bet that every team has investigated leg power this time. They will already know the tradeoffs and I'd be surprising if anyone scrambled to change immediately. Perhaps the bigger advantage is there might be potential to sail the boat differently. For example, the cyclists have their hands free, so they could be doing other jobs - perhaps controlling wing twist to match real-time aero targets. (I suggested Jimmy steer the AC72 from a bicycle seat so he could grind and steer. I got a very short answer)

Manual grinding vs Cycling , the differences this time;
- The rotary hydraulic pump is automatically changing gears so the pedals are always rotating forwards. (Whereas winches change gear by reversing the handle direction)
- Accumulators are now used to store pressure which can be used later when power requirements peak during a tack say. This allows the grinders to work more steadily.
- The AC50 is short of manpower, so any increase will result in better boatspeed because the wing and foils can be trimmed more frequently. This allows more precise sailing and faster foil designs - which need more frequent adjustment.
- The brief video of a tack shows 2 grinders being seated and cycling at different times, so maybe there are individual clutches so they don’t have to coordinate joining with spinning pedals?

In 1977 12m Sverige used leg-power with grinders belowdecks. Later, rules had the grinders on deck, and seated grinding was seen as too difficult because crew had to move around the boat. Many jobs started with very high speed and finished with very high load, which suits arm power.
Also, generally there was sufficient manpower and usually plenty of recovery time so there was no compelling need for a new system. (Although a grinder on KZ7 told me he fell asleep on the pedestal very briefly between tacks in a ~50 tack duel with Stars & Stripes in 1987)
-
I asked him also on AC Foil sets availability:
CSN: I checked with Pete Melvin if rules allows to change the 2 sets of foils according to wind conditions (if they are different designs of course) and he said his view based on the protocol is they can use both sets. Now what would you do? Have two diff designs or a spare one?
Mike Drummond: "I would use two different designs because it pays to be fast! Slow foils with a spare set probably guarantee a loss (at the least you're relying on your opponent having problems in multiple races); whereas fast foil sets might not break."

EMIRATES TEAM NEW ZEALAND LAUNCHES THEIR RACE BOAT FOR THE 35th AMERICA'S CUP

"Just 100 days out from the first race of the Louis Vuitton America’s Cup Qualifiers, Emirates Team New Zealand accomplishes the most significant milestone of its challenge for the 35th Americas Cup by christening their America’s Cup Class catamaran that will begin racing in Bermuda in May.

In the presence of the team, their families, the Sponsors and the official suppliers, the boat was christened at the Beaumont Street base in Auckland by Tina Symmans - member of the Board of Directors of Emirates Team New Zealand - and blessed by Ngati Whatua.

“This is a really proud day for the team collectively.” said CEO Grant Dalton. “The campaign always

Oracle AC50 launched


Pity this time we couldn´t enjoy different platform designs as in SF, although certainly all might have look rather similar this time around the One Design mold  rule takes out great part of the allure of the Americas Cup.
AC50s are still weapons and Oracle will be performing to defend the Cup, they have a solid sailing team and excellent design drive from San Francisco.
But a Box Rule a la F18 or A-Class wouldn´t have much impact on platforms build costs in my view, in the end is shape diff and not amount of material or system not allowed by the rule itself. Let the boat to be built in each country also with full control but done under a Box rule.

Even at beachcat level, imagine the F18 or AClass all being built from same mold, same specs, same beam position et all, much or simply all what makes those Classes a success will be lost.

Spithill says this is the boat that will give Oracle the Cup again, I say he is right , this boat in fact will bring the Cup home to Oracle and any of the Challengers also, as all will be racing same exact platform seen above.

Team New Zealand refused to follow suit and wen innovating, at a risk surely on the cycling, but they took same chances, even bigger ones last time when they decided to go foiling.

As nothing interesting is going on in the design aspect TNZ and Oracle are having a 'tough' fight in... facebook. Check TNZ take at Oracle on SoftBank Team Japan having a clone, with Oracle responding NZ did the same with Prada.

The only 'little' difference as stated by New Zealand in the same thread is that they were two challengers trying to take the Cup, and Softbank is collaborating with the Defender.-

Team New Zealand AC50: "Cycling the Cup" by TVNZ




Source TVNZ : tvnz.co.nz  --
Cycling stations?? Check those main foils... look like light air specs and scaled up /refined version of Artemis first foils from last Cup, wonder how they'll work in 20knots, although with the new push button control panel they have a wider range of active settings.

Below post from last night "Americas Cup 35: Team New Zealand innovates again".
Check Galdwell / Sail-World local report here-

Photo: Richard Gladwell / Sail-World - Last Cup edition they made their AC72 airborne which will stand as major development ever in the history of the Cup, but they also fitted a wheel while Oracle installed a frankenstein tiller system.
Team New Zealand had everything to win last Cup, and they had 9 Match Points to achieve it. They couldn´t but they broke through as they use to.
New Zealanders are not only the best sailors in the World but also have some of the wisest guys in the business. Just remember the 'hula' , Oracle Trimaran Wing among others which came directly from Mike Drummond's mind. Now the Kiwis have put pedal to the metal literally discarding the manual grinding stations by cycle style ones.  We wrote last weeks New Zealand are our favorites based on their top notch crew (Ahsby , Burling , Tuke and others)  and also on the non appealing OD platforms. If TNZ managed to design foils par to Oracle this display of drive and innovation will push them even closer to the Finals and recover the Cup.

On the platform itself (Hulls/ Beams / case pos)  not much to see,  it's all One Design , same mold... yupi .. exciting Americas Cup... not a chance. I'll take you OD a la AC45F or GC32, where the entire crew has an active sailing task, and not like the AC50 where you have 90% grinding and the rest pushing buttons.
Oracle 'unveiled' their clone today also. No pics yet.

Sail Test: 26 knots for the iFly 15





All images by Arno Terra & Michael Miller.  - Nice to have Arno testing the iFly 15, I have sailed the F20, FP and sal regularly foiling As, but didn´t have the chance yet to sail the S9 (couldn´t sailed it at Punta Ala 2015) or the new iFly.

Arno has been helping to develop the double luff Heru sail for his A-Cat and now also equipped in the iFly 15.

A priori one would think that recreational cats with double wand systems are super stable but not that fast, mainly on the drag factor (Sunnuck's M20 Vampire is another toy altogether and has tilted Ts main foils).

26knots was the guys recorded at our local Club two weekeends ago on the FP and the F20 on excellent flat day a good breeze (these two boats are capable of +30knots no problem though)  and I don´t have much reports from As above 25knots, 24knts achieved by Sandro and others, also by Mehl here last month on the F1. Mischa, Bundy and Brewin for sure have that range too but no has showed yet a 27 or 28 knots run for that matter. This only to put in perspective what Arno has achieved on the iFly

Check report by Arno below aboout his rides on the iFly 15. For detailed pics of hardware and conf check previous iFly 15 posts.

iFly 15 First fast active flight by Arno Terra
"Week 5 of this year I flew to Alicante to test sail the iFly prototype on the Mar Menor, a well know spot for boat testers in the winter months.
It was my first flight on a boat with active controls. Active controls as in the Moth with a wand and movable flaps.
To my surprise I clocked in my first flight directly a 26.2 kt run, a speed I never accomplished on my foiling A-class.

Circumstances were not ideal, it was very gusty, I struggled with the sheeting but nevertheless I felt in control and to my surprise I did not even miss the footstraps. I could easily adjust pitch by moving my body fore and aft and never lost my balance. When I luffed too much to control the boat, the boat did heel quite a bit to windward but had never the tendency to capsize, where in the A-class it s quite easy to capsize to windward if you luff to aggressively.

High speed can only be accomplished in a small boat when efficiency is high. It looks that the four foil active system is a worthy alternative for the four foil Z board system.

Both systems have their own strengths though. The active system adds complexity and by that costs but is easier to handle for the non experienced sailor. e..g. I could easily foil downwind while sitting on the side, something I could not manage on my last A-cat.

Foiling gybes are also quite easy with the active system as the flaps can effectively double lift and keep you foiling in the gybe.

I sailed the iFly with the big rig. For the iFly two rigs have been developed, One with a 7.5m mast and 12.5sqm and one with a 8.5m rig and 14.5 sqm.

The small rig is easier to sail and once foiling it does not feel small.

The idea behind the big rig is to offer lower lift-off speeds with just a mainsail and more depth downwind once foiling. It is just the rig for the high performance sailor who wants to optimize his VMG. It is more of a handful and you have to adjust the trim and settings more often, where the small rig operates in an almost automatic mode.

Indeed a more recreational foiler vs a more high performance machine. The big rig has a sail area to weight ration comparable to that of an A-cat.

The advantage of the four foil Z board is configuration is that it unloads the windward board automatically once there is some sideslip/leeway. That's why you see the full bottom deck sweepers and the high position of the traveller.

With the small rig on the iFly you do not have to unload the windward board, which has the advantage that it is almost impossible to capsize the boat to windward. Once you drop the windward hull the extra lift created by the flaps is more than enough to righten the boat and prevent a capsize.

Top speeds with the small rig are still mid twenties, just the angle is a bit higher than with the big rig or on an A-cat.

With the big rig you have to unload the windward foil by adjusting rake with the worm drive to get maximum performance.

The small rig boat has also the option to set a Code F, which is basically a flat code Zero set on the hull instead on a pole. It seems to work fine but I have not sailed it myself, but it is definitely an option to have fun in the lighter winds.

Strong points of the active foils are the pitch stability and the ability to have foiling gybes and perhaps foiling tacks. The pitch stability is why you see such high consistent speeds and why you do not need the footstraps.

I feel that there is a future for both the 4 foil Z board configuration and the 4 foil active flight configuration. Foiling newbies I can recommend the active flight system both for fun and safety. The racing enthusiasts will still be better off with an A-cat or Moth, but once the iFly has established itself as racing class we will see competitive racing on active flight boats too.

It is simply not true that the active boards make the boat easier to race, it still takes a lot of skills to get the max performance out of the boat, but indeed it is easy to foil and have some foiling fun.

Glad to have the Sweden team investing in media coverage for their campaign, they are doing the work of ACEA in this regard. More footage from Bermuda , onboard & drones.

Plus some surfski paddling, which is a great training tool. As kid we trained K1/K2s, and still have to row the surfski I designed, my brother still to finish cedar male mold, although another custom wood version has been already tested in the US (click photo left) by a paddler & builder I gave him the cad file, Walter Kirchhoff , who was finshing the built, but couldn´t help to launch it!  More on this soon.

Mikey Howser, in Memoriam


Really unexpected have Mikey Howser passing away, months ago I met him and Faye here in Buenos Aires as he came to race the F18 Worlds, I managed to get a charter for them and since day 1 from mail exchange the only thing I knew from them was a constant thanks and good will.

Then when we met here, it was the same, good will and eager to sail and having new experiences, as the trip they made to our Patagonia later. Mickey worked in the Cat community as a dealer and I'm glad to see one of his later works was delivering Nacra 15s to the kids along Pete Melvin.

A memorial will take place on February 14, 2017 from 11am - 3pm at the San Andreas Memorial Chapel 254 W. St. Charles Street, San Andreas, CA 95249.

Below some words of a fellow F18 sailor and friend Rich Vilvens :

"Mikey Howser passed peacefully at his home on 9 Feb 2017. Most people know him from the sailing community as the man who was always positive. He would travel with his wife Faye to events all around the world.

Formerly a dealer for Hobie Cat he had in the last few years became a Nacra distributor. His love for being out on the water was contagious. He would encourage the young and old to keep sailing and keep going. Always having time to help out with rigging or having that part you needed. Recently he helped to bring the New Youth boats to the West Coast and organized set up and rigging.
Many didn't know him outside of sailing, however he was just as active there. He was a Father, Grandfather, Uncle, Brother, Husband and a friend. A former pilot in the Air Force, ski enthusiast, entrepreneur, poker player and avid outdoors man.

His family and friends are saddened by the sudden loss, however all our lives are better and fuller for knowing him."

Sail On Mikey!

TF10 Foiling Trimaran by MM & built by DNA



Renders sent by DNA Performance Sailing , click images for HQ & Slideshow.- The TF10 Trimaran was born on the initiative of Andrew MacPherson, aka Macca, he has working on it for some time before the recent launch announcement and is always nice to have him behind all the new weapon multihull projects. Macca was there for the development of the Nacra F20, also for the initial steps of the Flying Phantom , the GC32 and now he was the driving force for the Morrelli & Melvin designed TF10.

Macca: "The project began after I met with a group of owners from the East Coast (US) and proposed them a smaller foiler, but they came back to me after the presentation and asked me work on a larger boat for them in conjunction with Morrelli & Melvin"

The TF10 will be a foiling trimaran featuring MM latest Nacra MKII foil development, amas foils shape and rudder winglets are a direct heritage from the work done with the Nacra MKII.

Similar Trimara foiling projects I can remember are Miartin Fischer Jessica Rabbit and specially Tony Grainger Rocket Factory Triamarans form 2014.

DNA performance Sailing is going to build it. I remember when PJ & Arno started working with the DNA A-Class, which was PJ's Holland Composites factory 'toy' project. The DNA A-Class exposure and results on the water led Gunboat to hire HC to built the foiling racer G4, which expanded the factory boat production.

Now HC boat division, 'DNA Performance Sailing BV' will be handed the build work for this flying Trimaran which will put them as a top advanced multihull foiling composites builder with their previous Gunboat G4,  DNA F4 and DNA F1 Cats projects..

More details when available, below some updates by Thijs van Riemsdijk on the TF10:
"We are working with M&M on the last details, platform is all sorted and have now collectively dived into the smallest of components for detailing. Once all is final we will share all tech to be published.

Tooling is well underway by now; combination of carbon and milled aluminum moulds. Production of the first boat will start in a few weeks from now and we plan to be sea trialling in June latest."
