Article on Rudy Choy and the development of the pioneering C/S/K Catamarans

From the following article on the excellent outrig.org site

Tribute to the Living Legends: Designers
RUDY CHOY

After “Catamarans Offshore”
By BARRY CHOY

In 1970 the MacMillan Company published “Catamarans Offshore,”
a watershed book written by Rudy Choy in an attempt to set forth
the legacy of his famed partnership C/S/K and totell the story
of how he and his partners, Warren Seaman,
Alfred Kumalae and Vince Bartolone, evolved their ideas
and principles of successful catamaran design. From the
earliest beginnings, specifically the late 1950s, they understood
what even some of the most skeptical and hardened
yachting traditionalists have only recently come to
accept: that multihulls are not only superior to conventional
yachts in many respects, but more importantly, are
the wave of the future. From the very beginning Rudy,
Warren, Alfred and Vince’s fundamental design standards
were creativity, simplicity and evaluation by careful empirical
observation, notions that today stand anyone desirous
of building anything operating according to the
laws of physics, in good stead. The acid-test of success for
each of their creations was conducted, not by using a slide
rule, or with the boat tied to some dock as a showpiece,

but in the open ocean.

Nixe Proa, build progressing well

Some time ago I put up a link to this interesting thread on the Proafile forums, this proa is being constructed using the tortured ply or "stressform" technique in Thailand.  The builder "Alexander" has made excellent progress and the most recent updates are here

Artemis team, crew changes for the AC72 program

Sail-World article by Richard Gladwell

http://www.sail-world.com/Australia/Americas-Cup:-Hejda-Terry---Artemis-Racing-ring-changes-in-AC72-crew/104274

After just four days of sailing in the their new AC72 America's Cup Challenger, Artemis Racing, have announced several key changes in the afterguard.

Gone is skipper, Terry Hutchinson, who has been with the team since its inception, and on-board are a bevy of Olympic Gold Medalists, plus highly experienced multihull skipper and technical specialist, Loick Peyron.

The Challenger of Record for the 34th America’s Cup, announced a new afterguard featuring Olympic Gold medalists; Iain Percy (GBR), Nathan Outteridge (AUS) and Santiago Lange (ARG) as well as Loïck Peyron (FRA). Artemis Racing believe the technical and multihull experience of this group will provide an efficient nucleus to guide the team’s AC72, particularly through the next few critical months of sailing and testing.

Iain Percy will also act as sailing team director. CEO Paul Cayard is still listed as tactician.

New F-22R launched in South Africa

From F-boat.com news updates page:

http://www.f-boat.com/pages/News4/F-22inSouthAfrica.html

Peter How has just launched his F-22R on Gariep dam in South Africa and writes:

Hi Ian

Most of the bugs sorted out now, including the jib furling. Upwind it points well and sails almost
at the same speed as the apparent wind on my handheld meter.


Sails hands off in a straight line. Folding the floats on the water for docking on the trailer each
day is very easy. The low weight and wide mast cord make it risky to leave out next to a jetty with our Karoo
winds (60 knots downdraft measured at Oviston down the lake last week).

Peter Hoejland's F22-R sailing update

Sailing update from F-boat on Peter Hoejland's F-22R which he launched last year.

http://www.f-boat.com/pages/News4/F-22inDenmark2012.html

Peter Hoejland launched his F-22R last year, and has now completed a full sailing season. Peter writes:

Hello Ian

End of first season with the F-22R. Here in Denmark it is almost winter and no more sailing until spring

The boat has behaved and performed beautifully. We have not done a lot of racing, but the speed is
impressive. Other multihulls have to be a lot bigger to keep up, and we are constantly improving,
especially as we get more comfortable with the boat and put more pressure on her. It can take a lot
more wind than you think


It goes up (and down) wind and tacks with any sail configuration. Also jib only, if we want to take it
easy. That is a very nice feature when the wife and I are cruising. On the other hand she is also getting
addicted to the speed, so not much taking it easy.

VESTAS Sailrocket 2, the 65 knot+ record run

From Paul's blog, description of the latest run which has lifted the bar again to over 65 knots (thats over 120 km/h for the non nautically inclined). 
 
 
Blown Away... The 65 knot+ run (With video)

So let's get this down here before I start forgetting stuff...Last Saturday looked like it was going to be a strong day from the moment it popped onto the long range Windguru forecast. Amongst a bunch of fluctuating average days it barely deviated as it approached. We began to focus on it as being the day when we would go all out. Almost annoyingly, the day before piped up and blew just enough to force us to fully gear up and head towards speed-spot. We stopped just short of launching the boat. It was annoying as it was strong enough to force us to react but we really wanted to focus on the next day. You have to be reactive as for whatever reason, the next day may not deliver. Every opportunity has to be seized this year and we had already had two remarkable days on average forecasts.
That night we had dinner back at the crew house. I was about to raise a glass to the following day and the last day of living in the 50's... but decided not to tempt fate. We had an early night.
It was already blowing from the SW in the morning. This combined with the strong forecast spoke to us that at long last, after over six weeks, we were going to get some good, old-school, industrial Walvis Bay wind.

Atlantic Rally for Cruisers, Multihulls to start 27th November

From bymnews.com

http://www.bymnews.com/news/newsDetails.php?id=112192

Atlantic Rally for Cruisers Start Day 1 - Sunday
 
Sunday, 25 November 2012

At 0915 UTC today the ARC Office was still collecting information from the boats about their preferred start day. It is expected that all of the racing fleet will start today, plus some of the larger cruising boats. We expect the multihulls and the majority of the cruising division boats to remain in Las Palmas until the second start on Tuesday 27th.
 
All of the ARC boats are fitted with Yellowbrick satellite trackers, so are visible at all times on the Fleet Viewer http://www.worldcruising.com/arc/viewer - this allows every to see where the boats are, their exact position, heading and boat speed. The information is updated every six hours.

US Multihull Championships (F16 Catamaran)

An article from Sail-World.com by Jake Fish summing up the event which was dominated by Sarah Newberry and Kenny Pierce with 14 wins in 14 races.

http://www.sail-world.com/Australia/U.S.-Multihull-Championship---Historic-victory-for-Newberry/103890

Sarah Newberry (Miami, Fla.) and Kenny Pierce (Hialeah, Fla.) ended a perfect week by finishing first in Sunday’s only race. The duo claimed victory in the 2012 U.S. Multihull Championship, hosted by the Pensacola Beach Yacht Club, with 14 wins in 14 races. Not only were they undefeated, but Newberry made history by becoming the first female skipper to claim the U.S. Multihull Championship for the Hobie Alter Trophy, a US Sailing National Championship.

'I’m so pleased and so honored,' said Newberry, who was sailing in her fifth U.S. Multihull Championship, all as a skipper. 'It was great to sail with Kenny this week, who’s such a great sailor, and has been a hero of mine.' Newberry and Pierce are members of the Miami Yacht Club. Pierce is the 2006 Nacra 20 National Champion.

Newberry and Pierce won by a 23-point margin over Sandra Tartaglino (Tiverton, R.I.) and crew Glenn Holmes (Pensacola, Fla.). Finishing third was Eric Witte (Fairfield, Conn.) and Tyler Holmes (Panama City, Fla.).

Vestas Sailrocket 2 record, A new outright nautical mile record has been set

More from Paul Larsen, the team have now smashed (subject to ratification) the nautical mile record.  No mean feat considering the limited space available in flat water at Walvis Bay in Namibia to do their runs.  The new record is 55.32 knots for the nautical mile with at 63.98 knot peak speed.

Vestas Sail Rocket :Update from Paul: New PB... and nautical mile record smashed
 
Sunday, 18 November 2012

Just in after the most incredible run. A whole nautical mile dipping well into the 60's on each gust. We peaked near or over 64 knots and beat our previous 500 meter average. I don't think we cracked 60 knots as a 500 meter average though. But anyway... we smashed the nautical mile record. The TRIMBLE file is big but on the small GT31 we averaged over 55.5 knots
 
(Hang on STOP PRESS: Trimble data in now... 55.32 knots for the mile subject to wssrc ratification. That's it).
63.98 knots 1 second peak... so definitely over 64 for a spike in there.
... and just marginally quicker than our previous best 500 meters at 53.38 knots... subject to wssrc stuff!
 
It's not an easy run to do on a course that is only 1.04 nautical miles long. I have to wind the boat up in rough water at the start and launch it out into rough water at full pelt at the end. Bloody interesting sailing in a boat specifically designed for flatter water.
So that was a big tick on our job list. We didn't even think we were going sailing today. Our media job list is huge and we had to drop everything to go sailing. The team is getting slick now and we made the switcharoo to sailing mode pretty effectively.
So it's Sunday and the town is shut. We're alone in the container with one paltry bottle of Pol Roger champagne left. Our local Champagne dealer is enroute.
This boat is wearing us out. We have barely recovered from the first hangover.
Damn that was good ride. I had the time to look around and just enjoy the sensation that that awesome piece of kit delivers. She was on the edge there a few times.
 
Bloody brilliant. Go Team.
 
Enjoy all. Cheers, Paul
 
 

Goolwa to Meningie race in South Australia from the deck of a Nacra 5.8 catamaran

Writeup by "madboutcats" on Sailing Anarchy forums about the Goolwa to Meningie race on their Nacra 5.8 beach catamaran.

Another great Goolwa to Meningie race, about 13 trailer sailers headed of from Goolwa in a very light head wind at 8am followed by 13 catamarans at 11am, including A Classes, Black Witch, Yvonne, Taipans, Nacra Infusion, Nacra 5.8’s, Hobie 16’s, my daughter Maeve and I on the Nacra 5.8 with spinnaker, still in the same wind, it was tedious in the warm sunlight trying to keep the boat going faster than 1 knot for the first hour so I took of my spray top, (you can guess what happened hours later when the wind hit), I readily admit to being a very bad light wind sailer and much prefer the wind over 20 knots as I find the closer to 30 knots the less skill I need. During this light air race we were coming last for a fair while which always gets Maeve grumbling, after the second hour the wind picked up to a starboard tack with some blustery swings enabling some ground to be covered, a gust sent the Black Witch over in the channel. The wind firmed up a bit after 1pm as we exited the Goolwa channel onto a nice spin run across the top of Lake Alexandrina where we got to a top speed of 16.4knots, we travelled that 20km in what felt like no time, until we got close to the entrance to the narrows where we were knocked down twice with some heavy wind shifts, these made us do wild bare aways, then spun us around with our mast close to the water before again filling the spin from behind and pulling us back up saving the capsize, a similar gust probably got the Taipan 5.7 of Tim Wright’s just as he was dousing the spin, they got hit with Josh going through the sail and bending the boom. We put the spin away and reached into the narrows. Some boats said they did numerous tacks in the narrows but we hit it with good speed and just limped past the ferry before we got a gust with a lift to get us into the channel, we overtook the leading six trailer sailers in the narrows. There was much less reeds than last year with more room, as the channel twisted and turned we went from reach, downwind, upwind, reach, upwind with a final four relatively quick tacks to get onto the lake in good solid wind. When we got onto lake Albert the only boat in sight was the Yvonne which was so far in front we could just see the red boat and sail, it was a good solid SSW wind, with top gusts around 20 knots with no holes in it, the wind had thrown up two to three foot chop and you guessed it, it was friggin cold without a spray jacket on, it was two on the wire, heaps of downhaul, point up as high as we could maintaining power, to push through the waves, with constant spray coming over the boat and down the top of my wetsuit. We made good time across the lake and only had to throw a small tack in to cross the finish line at the end.
At the time of writing this I didn’t have the full results. First cat over the line was Steve Kroon and Katrina on the Nacra Infusion F18 in 4hrs 28mins, first on handicap was Marcus Towell and his son Nathan on their Yvonne in 5hrs, fastest Meningie club member on handicap was Mick McGuire and Hugh on the Taipan 5.7 in 4hrs 34mins, we only just beat the Yvonne over the line and we were probably last on handicap but we learnt a bit more about light lake sailing and using the spin. This is still the best race in Australia, doing the last 40km in next to no time is an absolute buzz see you there next year.
