Dufour 41: Dufour Yachts unveils its new sailing boat

Dufour Yachts is unveiling its new model 2023/2024: the Dufour 41

While the Dufour 37 has been a huge success since its launch last September, Dufour continue on this course and to offer you a sailing boat of over 12 meters in length which will complete the range by replacing the Dufour 390 and 412.

At 12.75 metres, this yacht designed by the shipyard’s design team in close collaboration with naval architect Umberto Felci of the Felci Yachts Design and interior designer Ardizio Design, will seduce you and provide you some sailing unique. Particular attention has been paid to moving around on board this yacht, with large living areas both inside and outside.

A innovative new concept

“With this boat, we’ve gone even further in developing the new concept initiated on the Dufour 37: to offer high-performance sailing boats with beautiful volume” – Umberto Felci, naval architect.

This new concept really comes into its own with the Dufour 41. With style, yet maintaining all its functionalities, this new model will meet all your expectations whether you are a future owner or also for charter companies.

The shipyard’s watchword: maintain the Dufour DNA. To build and design high-performance , comfortable and innovative boats. Aboard this 41-foot sailing boat , you’ll appreciate the large cockpit, comparable to that of a much bigger yacht, with its comfortable seating and redesigned cockpit table and a proper, comfortable aft platform similar to the one on the Dufour 470. The wide side-decks will allow you to move from bow to stern and back again, easily and with complete peace of mind. The exterior layout of the Dufour 41 has been redesigned and the helm stations have been created with particular attention to the distance between the helm seat and the wheel, for comfort under way. You’ll enjoy helming this yacht as well as some great sailing sensations.

From outside to inside

This new sailing yacht is offered in two versions: either 3 or 4 cabins. Both versions have a similar configuration, with each version featuring a spacious saloon, a functional and central fore-and-aft galley, as well as twin aft cabins with good headroom.

This model has a completely new galley where two can cook together easily, with a large worktop and direct communication with the saloon.

Aboard the 3-cabin version, the owner’s cabin offers you a luxury yacht -like experience with its own bathroom. In the 4-cabin version, you’ll find two proper forward cabins with 145cm beds, i.e. real double beds. This arrangement is a first on a yacht of this size and the Dufour shipyard has paid particular attention to the soundproofing between these two cabins with a proper bulkhead to respect the privacy of your guests or of the crew. 

Choices for all types of programmes

A new feature, and a significant one at that, has been developed on the Dufour 41. You’ll be able to choose between three options for your bathrooms:

• A proper heads compartment with toilet
• Storage space

This is a genuine opportunity for owners to choose to fit out their future yacht with a real bathroom in the owner’s cabin, and to choose between a shower and a storage space for the aft cabins, for example.

Luminosity and clarity

One essential feature that sets the Dufour 41 apart from her competitors is her luminosity. She enjoys around 60% more natural light than other yachts available . Thanks to its numerous openings with sea views, you’ll be able to take full advantage of the environment around you.

Living in and out

Indoor/outdoor living takes on its full meaning aboard the new Dufour 41. A unique yacht where performance and comfort on board are intelligently combined.

FEIG ELECTRONIC: Moscow-City Skyscrapers Streamline Parking Access and Control with Secure RFID

Feig electronic partners with isbc group to deploy ucode dna rfid security and parking access control solution in moscow business district.

Weilburg, Germany  — December 3,  2019  —  FEIG ELECTRONIC , a leading global supplier of radio frequency identification (RFID) readers and antennas with fifty years of industry experience, announces deployment of the UCODE DNA RFID security and parking contactless identification solution in the Moscow International Business Center, known as Moscow-City, one of the world’s largest business district projects.

The management of Moscow-City not only selected long-range, passive UHF RFID to implement in its controlled parking areas, it also chose to implement UCODE DNA , the highest form of secure RAIN RFID technology, developed by NXP Semiconductors.

“Underscoring NXP’s innovation and leadership in developing advanced RAIN RFID technologies, our UCODE DNA was chosen to be incorporated with the FEIG and ISBC implementation of the contactless identification system in the prestigious Moscow-City,” said Mahdi Mekic, marketing director for RAIN RFID with NXP Semiconductors. “This exciting project represents yet another successful deployment of NXP’s contactless portfolio, and showcases our continued ability to meet the high-security requirements of highly demanding applications without compromising user convenience.”

“UCODE DNA is considered the only identification technology to match the physical protection of a barrier with the cybersecurity necessary to truly protect entrances from unauthorized access,” said Manuel Haertlé, senior product manager for FEIG Electronic. “As a respected contactless payment technology company, FEIG applies security know-how from its payment terminals, which are fully certified according to the latest high-class security standards, into our RFID systems. FEIG vehicle access control RFID readers incorporate advanced secure key storage elements, supporting various methods for secure key injection.”

FEIG’s partner ISBC Group provided the knowledge and support for this successful implementation using  FEIG’s long-range UHF RFID . The resulting system enables authorized vehicle entry into areas reserved for private residential use or corporate tenants, while also allowing availability of temporary, fee-based visitor parking. Thanks to the cryptographic authentication of UCODE DNA, both the tag and reader must go through an authentication procedure before the reader will validate the data from the tag, which is transmitted wirelessly. This level of authentication is typically used in the most secure data communication networks.

“The system’s two-step authentication means that only authorized equipment can handle the secure protocol and the data exchange with the UCODE DNA based tag. Without the required cryptographic secrets, other readers would query the tag in vain, because the tag’s response cannot be interpreted or understood,” said Andrey Krasovskiy, director of the RFID department at ISBC Group. “On top of this, each data exchange in the authentication process is unique, so even if a malicious actor were to intercept the communication, the transmission is only good for a single exchange and the tag’s unique identity is protected from cloning.”

Established in 1992 and still growing, Moscow-City is the revitalization and transformation of an industrial riverfront into a new, modern, vibrant and upscale business and residential district. A mix of residential, hotel, office, retail and entertainment facilities, it is located about four kilometers west of Red Square along the Moscow River. Twelve of the twenty-three planned facilities have already been completed, with seven currently under construction. Six skyscrapers in Moscow-City reach a height of at least 300 meters, including Europe’s tallest building, Federation Tower, which rises more than 100 stories.

Partnering with ISBC and deploying FEIG Electronic RFID solutions, the Moscow International Business Center is delivering security and access control to its city center today, as it grows into the city of tomorrow.

Dufour 40 is a 40 ′ 5 ″ / 12.3 m monohull sailboat designed by Umberto Felci and built by Dufour Yachts starting in 2005.

Rig and Sails

Auxilary power, accomodations, calculations.

The theoretical maximum speed that a displacement hull can move efficiently through the water is determined by it's waterline length and displacement. It may be unable to reach this speed if the boat is underpowered or heavily loaded, though it may exceed this speed given enough power. Read more.

Classic hull speed formula:

Hull Speed = 1.34 x √LWL

Max Speed/Length ratio = 8.26 ÷ Displacement/Length ratio .311 Hull Speed = Max Speed/Length ratio x √LWL

Sail Area / Displacement Ratio

A measure of the power of the sails relative to the weight of the boat. The higher the number, the higher the performance, but the harder the boat will be to handle. This ratio is a "non-dimensional" value that facilitates comparisons between boats of different types and sizes. Read more.

SA/D = SA ÷ (D ÷ 64) 2/3

• SA : Sail area in square feet, derived by adding the mainsail area to 100% of the foretriangle area (the lateral area above the deck between the mast and the forestay).
• D : Displacement in pounds.

Ballast / Displacement Ratio

A measure of the stability of a boat's hull that suggests how well a monohull will stand up to its sails. The ballast displacement ratio indicates how much of the weight of a boat is placed for maximum stability against capsizing and is an indicator of stiffness and resistance to capsize.

Ballast / Displacement * 100

Displacement / Length Ratio

A measure of the weight of the boat relative to it's length at the waterline. The higher a boat’s D/L ratio, the more easily it will carry a load and the more comfortable its motion will be. The lower a boat's ratio is, the less power it takes to drive the boat to its nominal hull speed or beyond. Read more.

D/L = (D ÷ 2240) ÷ (0.01 x LWL)³

• D: Displacement of the boat in pounds.
• LWL: Waterline length in feet

Comfort Ratio

This ratio assess how quickly and abruptly a boat’s hull reacts to waves in a significant seaway, these being the elements of a boat’s motion most likely to cause seasickness. Read more.

Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam 1.33 )

• D: Displacement of the boat in pounds
• LOA: Length overall in feet
• Beam: Width of boat at the widest point in feet

Capsize Screening Formula

This formula attempts to indicate whether a given boat might be too wide and light to readily right itself after being overturned in extreme conditions. Read more.

CSV = Beam ÷ ³√(D / 64)

Performance version shown. Optional draft: 2.10m/6.9ft Optional disp: 7900kg/17,416.5lb Optional ballast: lead 2690kg/5930.43lb

Moscow: City, Spectacle, Capital of Photography

April 30–june 21, 2003.

Moscow: City, Spectacle, Capital of Photography , an exhibition of 20th-century photographs of Moscow, opens at Columbia University's Miriam and Ira D. Wallach Art Gallery on Wednesday, April 30, 2003 and remains on display through Saturday, June 21, 2003.

Moscow has been a powerful magnet for many Russian photographers of the 20th century. Moscow: City, Spectacle, Capital of Photography presents the work of 31 photographers, whose images have defined the visual experience of Moscow from the 1920s to the present. Diverse in form and strategy, the 90 photographs chosen for the exhibition trace the history of Russian documentary photography and offer insight into individual practices. From Aleksandr Rodchenko's constructivist visions and Evgenii Khaldei's humanist landscapes to Igor Moukhin's scenes of urban spectacle and alienation in the works of Russia's key 20th-century photographers, Moscow ventures beyond the expected image as a site of famous landmarks, architectural treasures and dramatic lifestyles.

Early 20th-century photographers Boris Ignatovich and Arkadii Shaikhet saw themselves in the vanguard of an emerging mass-media culture, defining with their cameras the visual experience of Soviet modernity. For nearly 70 years, Soviet photography was assigned the duty of maintaining the ideological rigidity of the Soviet State. Yet, as examples of the work of Iakov Khalip, Anatolii Egorov, Mikhail Savin, and Mark Markov-Grinberg show, Soviet photographic practices were much more complex than has been previously acknowledged. The works of these photographers remain intensely compelling to a modernist eye.

Contemporary Russian photographers, such as Lev Melikhov, Valerii Stigneev and Sergei Leontiev, engage with the legacy of the Soviet documentary photography. But for them the documentary is a complex and multivalent genre, which incorporates subjectivity, ambiguity and reflexivity and comments on social and cultural issues without losing sight of the position from which that commentary is made. In the recent photographs by Vladimir Kupriyanov, Igor Moukhin, Anna Gorunova and Pakito Infante, the "real" space of Moscow is replaced by an imaginary and optical spaces of virtuality.

The works in the exhibition are on loan from Moscow's Cultural Center Dom, and many are being shown outside Russia for the first time. In conjunction with the exhibition, the Wallach Art Gallery is publishing an illustrated catalogue with a scholarly essay by the exhibition curator, Nadia Michoustina, a Ph.D. candidate in Columbia University's Department of Slavic Languages. The essay presents a nuanced history of Russian photography of the 20th century, and contributes to an interpretation of extraordinary images.
