Solo sailor Florence Arthaud killed in tragic helicopter accident
Florence Arthaud has been killed in a helicopter accident during the filming of a TV show. Perhaps most famous for her solo victory in the 1990 Route du Rhum on the ORMA60 trimaran "Pierre 1er" she continued her career in sailing well after that point also taking a Transpac win along with Bruno Peyron on the 86' catamaran "Explorer". A true inspiration to solo sailors worldwide we extend our sincere condolences to her family and friends. Fair winds and following seas Florence.

Design Catamaran team show renders of their new foiling catamaran model the Toro 34R
From the following entry on he Design Catamaran website:
http://www.designcatamaran.com/?modele=toro-34r-2&lang=en
Our original TORO34 flirts easily with 25kts and more off the wind… How could we make the Toro to blow 30kts? Design Catamaran is in the final stages of releasing the TORO34R, equipped with foils, a 6.1m (20’) beam and a 15.9m (52’) mast. This all carbon version will exceed all the performance characteristics of the original model. To be the fastest of your yacht club, have heads turn as you sail by and all within a controlled budget, Design Catamaran is offering this no compromise sailing beast : the TORO34R.
Life is too short to sail slowly … So Fly a TORO

Rapido trimarans, new website with details of Rapido 60 trimaran which is designed by Morelli and Melvin
From the following Concept and Design section of the Rapido Trimarans website:
http://www.rapidotrimarans.com/the-concept.html
CONCEPT and DESIGN
A yacht designed and built by real sailors for real sailors…..
…and meets CE A and ISAF Category 0 offshore for multihulls ( for trans-oceanic races and capable of withstanding heavy storms…).
Take the highly experienced sailors that have built more production trimarans than anyone else in the world and team them up with the best multihull design group in the world---the result is an innovative ocean cruising yacht, the first of its kind.
Safe. Seaworthy. Spacious. Stable. Fast. and Strong!
The Rapido 60, conceived by Paul Koch and Richard Eyre, and designed by Morrelli & Melvin will set the benchmark for genuine performance ocean cruising yachts.
We are not talking about a stripped out racing yacht pretending to be a cruiser or a super expensive cruiser that makes performance claims that cannot possibly be lived up to due to weight.
Round the world and distance records are held by trimarans for good reasons. They are easier and safer to handle even in the storms of the Southern Ocean. They are more comfortable and faster on all points of sail. They are easier on the crew because the motion of a trimaran in the sea is superior to both monohulls and catamarans.
Monohulls typically sail at least 20 degrees of heel and roll at anchor, which makes living aboard uncomfortable and even exhausting. Catamarans are extremely comfortable when moored and at the boat show and many inexperienced sailors are seduced by this false sense of comfort.

Racing proa design 'Bucket list' by Rob Denney
From the following article by designer Rob Denney on his very interesting offshore capable and container transportable racing proa:
http://harryproa.com/index.php/design/20-racing/56-bucket-list
Bucket List has a fuse on the main sheet cleat which releases at 30 degrees of pitch or heel. If it does capsize, the buoyant mast stops it going past 90° from where the buoyant boom will right it without the crew getting wet.
The rudders kick up in a collision or grounding and are easily lifted, resulting in a 100mm draft with nothing to trip over on a breaking wave, and the ability to surf up the beach and step ashore as a last resort.
Large, easily replaced foam/glass buffers on the hull ends minimise collision damage.
The single sail rig means you never have to venture outside the beams. There is no dangerous foredeck work, and none of the dramas associated with extras. The wishbone boom is above head height if you are on the tramp.
The hulls are foam cored and compartmentalised. Even if it was severely holed, Bucket List would still float and could still sail.
The flexible mast automatically dumps power in an unexpected gust. The absence of stays means the sail can be reefed, raised, lowered or totally eased on any point of sail and any wind strength.

Windrider to distribute Astus trimarans in the US
From the following entry on Small Trimarans blog:
http://smalltrimarans.com/blog/?p=11924
Windrider has just Signed a deal with Astus Boats to sell their trimarans in the United States. The online version of the marine industry magazine, “Trade Only Today,” posted this news a few days ago (on August 27th).
That’s pretty neat. I’ve periodically wondered when (if) somebody would become an Astus dealer here in the US. The Astus trimarans are featured in the book, “More Small Trimarans.” You can also find out more about them at the website of one of their European dealers here.

Article on the Hydroptere program by Alice Myhre
From the following article (in French) on LePoint.fr
http://www.lepoint.fr/voyages/l-hydroptere-le-bateau-qui-voulait-voler-24-08-2014-1856147_44.php
The rough Google translate is below:
By Alice Myhre
They dreamed, they did! In 1963, the publication of The 40-knot sailboat Bernard Smith, navigate 72 km / h is science fiction. Forty-five years later, in 2008, the team of Alain Thebault shouts of joy when the Hydrofoil, flying over the waves, breaking the "wall of wind": 50 knots under sail (92.6 km / h)!
In Greek hydros means "water," ptère, "wing". You understand that this is a device that combines aerospace and marine engineering. "We're like weightless, 5 or 6 feet above the water: it was like being on a magic carpet," says Alain Thebault. The secret? The foils, kinds of shaped wings that move in the water. Thanks to them, the boats take off, only connected to the sea by three foils. Supported by these submerged wings, boats double their speed in the blink of an eye. While afloat, the speed of a sailboat is limited by its length, when it was drawn up on the foils, the water is no longer an obstacle but a fulcrum. Thus, Hydrofoil, with only 2.5 m2 in contact with the water, sailing at 30 knots with a wind of 15! It's wanting to overcome the laws of physics that some enthusiasts have devised this system. But it took a hundred years of research before coming to near perfection: the Hydrofoil Alain Thebault.
Suspended in the air
In 1861, wanting to test wings planned for the first aircraft, the British Thomas Moy discovered the principle of the hydrofoil. The idea, once launched, will spread gradually. Sailboats to powerboats, experiments are linked to the United States and Europe. Many engineers are interested, including big names such as Alexander Graham Bell. The latter, after having equipped with foils motorboats, Nancy realizes, a model sailboat equipped with this wing. We are in 1912 and eight years later, the first patent was filed by Malcolm Thomas McIntyre and brothers. Their boat he sailed really? It
remains a mystery.
Testing, from 1938, models in her bathtub, Robert Gilruth initiate a turn. In the living room of his apartment, the future director of NASA goes from scratch to develop the first hydrofoil on water: Catafoil. In 1941, in the Chesapeake Bay on the East Coast of the United States, this boat has a great foil in "v" takes off. "It was a great time, we sailed low in the water at about 4 knots trying to catch a sailboat ... After having passed, we got up on the foils. You can imagine their shocked looks when we went to about 12 knots, hanging in the air, "tell the pioneer.
Then, in the 1950s, Gordon Baker, technology enthusiast, dreams of designing a hydrofoil sailboat marketable. This project, funded by the Navy, gave birth to the Monitor. After seventeen years of research, Baker finally pilot his car, whose stability is surprising. Hands on a car steering wheel, it reaches 35 knots, a record that will not be beaten 35 years later! Paradoxically, this engineering gem can not find opportunities. Well, not quite. Ten years later, the American David Keiper, he still believes. He dreams of a foiling trimaran can take off. He designs the Williwaw. The boat, equipped with retractable foils, travels the oceans. It carries 20,000 nautical miles, solo or in teams. Even if it is not built for speed records, the hydrofoil is propelled into the era of sailing the high seas.
"We're going to be scared"
Meanwhile, Eric Tabarly, driven by instinct, think the future of racing through the multihulls. Aboard his giant trimaran Pen Duick IV, lighter, less sail and easier to maneuver solo skipper search pure speed. In 1968 he crossed the Atlantic in 10 days and 11 hours, smashing all records! A year later, he discovered for the first time a hydrofoil: the Williwaw. This face-to-face give him wings to embark on a new project: the construction of the Paul Ricard which transposes the foils on an "offshore racing machine."
The initial objective of improving the stability and drift boat is quickly exceeded. Engineers, especially Pierre Perrier, revved "They began their study, following the idea that I had given them, but less shy than me, they arrived quickly to take off the boat for them c. really was the way forward, "explained Tabarly. Based on a hull Tornado, they build a prototype in 1976 whose essays are dreaming. Unfortunately, the materials of the time did not allow to build the full-scale machine. Tabarly was stuck with the Paul Ricard, a pale copy that can take off only partially. Shortly afterwards, Alain Thebault intervenes. He contacted Tabarly, takes the original project and began building what would become Hydrofoil.
Between the first model produced in 1985 and the first record broken by hydrofoil in 2005, the team of Alain Thebault had to sail in troubled waters. "We flew over the area still little known high speed sailing. I think at times we will be afraid," confided at the time Alain Thebault ("The Hydrofoil, the breath of a dream" by Thalassa). Indeed, the challenge is to marry the lightness and strength of the boat. The foils must be particularly robust to withstand stronger than that experienced by the wings of fighter planes pressure twice. In addition, when the node 50 reaches Hydrofoil, water boils around airfoils, thus reducing the stability of the vessel, among others. A year after their first flight, floats breaks during an event at sea. "It [was] glad I brought the boat. This was not granted," recalls Alain Thebault. After several failed attempts, they finally manage to beat their first record.
The instinct of the Marine is not enough
It was in 2005 that the Hydrofoil IV gained a few precious seconds on 35 minutes set by the aviator Louis Bleriot between Dover and Calais. Then addressing the world speed records, the creature becomes the world's fastest boat. In 2008, breaking through the 100 km / h, the team will pay his madness a spectacular dismasted. "We really had the wind barrier This is quite extraordinary in terms of skiing and feel very airline. It ended badly, but hey, is cleared as pioneers. " But with a top speed of 56 knots (104 km / h), their pole position was thrilled later by Australian Paul Larsen aboard his Vestas SailRocket.
At such a speed, instinct alone is not enough. The crew of the Hydrofoil is assisted by an arsenal of electronic devices that measure every reaction of the boat. The democratization of this type of machine is not for now, even with the marketing of smaller models, such as the Flying Phantom One of Martin Fischer. After a hundred years of research, performance competition continues. The engineers of the future will win new challenges. , We await the day when the Hydrofoil will tour the world above the waves.

Yvan Bourgnon loses his catamaran on rocks in Sri Lanka while attempting to reach the shore during his beach cat circumnavigation attempt
Yvan Bourgnon's catamaran on which he has nearly completely circumnavigated has sadly been lost on the rocks in Sri Lanka. Yvan has thankfully survived without injury but the boat is a complete write off. His plan is to head back to France and attempt to raise funding for another catamaran built along the same principle of no accommodation and short LOA to complete his adventure.
Here is a rough translate of the news article:
http://www.en-avant-toute.ch/page/yvan-bourgnon.html
Big problem on arrival in Sri Lanka
"A few miles from the finish, the wind will was finally appeased; so I set the autopilot to sleep a few moments with a heading seaward. I woke up on a surf spot with huge waves crashing on the rocks. I was thrown out of the boat and thought I live my last moments being drawn in by a mishmash of pebbles, pieces of boat and water rollers. I'm out of it unscathed. It's just a miracle!"
This accident does not mark the end of my project. I intend to find a partner and additional funds in the coming weeks to arm a catamaran of existing sport and continue the adventure...
Yvan Bourgnon (August 1, 2014)
I've had a few people email me to see if there is anyway they can help Yvan complete his adventure. There is a donations page on his website here:

Multihull heavy weather tactics when sailing a catamaran offshore
From the following excellent article by Peter Johnstone on Sail Magazine:
http://www.sailmagazine.com/cruising/heavy-weather-strategies-when-sailing-catamaran
By their nature, larger catamarans are exceptionally safe offshore. It is not unusual to sail through mildly uncomfortable conditions, such as a gale, only to arrive in port and hear sailors on keelboats talk of “surviving” horrendous weather. A large modern catamaran has plenty of buoyancy and exceptional roll inertia. Together these make a capsize, or inversion, highly unlikely. A 30-foot breaking wave hitting a cat abeam will simply make the boat surf sideways.
On most offshore passages, advanced communications and weather information should preclude you from ever experiencing true gale or survival conditions. The highest risks are run on passages sailed on a north-south axis between seasons. Early spring or late autumn passages between New England and the Caribbean, in eastern Atlantic waters off Europe, or on routes between the South Pacific and New Zealand are where you typically have a chance of experiencing a good wallop offshore. Follow the wisdom outlined in Jimmy Cornell’s World Cruising Routes, and these risks should be minimized. Regardless, anyone venturing offshore in a multihull should be prepared to handle the worst.

of work in the new shipyard, the first CATRI model who really “designed to fly”
launched in Burtnieki lake. In contrast to the AC34 catamarans and their small
versions (Flying Phantom, Nacra F20C, GC32), the Catri 25 foiling height will
not exceed 5-8 cm. Hulls’ contact with tops of waves increases resistance
slightly, but it completely offsets by achieved stability. As a result, the new
foiling trimaran designed as an all purpose sport cruiser for both race and
family cruising.
