Hardback. Condizione: New. This is not your parents' Art and Science of Sails, written by Tom Whidden and Michael Levitt and published in 1990 by St. Martin's Press. The first edition sold more than 20,000 copies. The Second Revised Edition 2016 -- now in its second printing -- is published by North Sails Group, LLC and written by the same duo. What a difference 25 years makes! Today there are one-piece sails made over a 3D mold in the shape they will assume in the wind. Sail plans have radically evolved to fractional rigs, fat-head mains, and non-overlapping jibs. That is true for racing boats as well as cruising. Thus, ninety percent of the text is new, as are almost all of the more than 100 photographs and technical illustrations. The authors focus on circulation as they did in the first edition, but now come at it from a different direction. And for the first time anywhere, they attempt to quantify its effects. Where the wind speeds up and why as it passes over a sail plan, and where it slows down and why. Circulation theory is familiar to aerodynamicists for at least 100 years and is argued about by sailors at least since 1973, when the late Arvel Gentry loosed his theories on the sailing world.Gentry was an aerodynamicist at Boeing by day and a sailor on the weekends. And the theories used to explain why airplanes fly were at odds with the theories of why sailboats sail to weather and what the slot actually does. Whidden, CEO of North Marine Group, which includes North Sails, and Levitt, who has written 14 books, utilize explanations like circulation to answer such diverse questions as: Why fractional rigs, fat-head mains, and non-overlapping jibs have come to predominate. Why and how leech twist can be a sail-trimmer's best friend. Why a yacht designer positions the mast, keel, and rudder to create some weather helm. Why the safe-leeward position is advantageous relative to the entire fleet, not just to the boat you tacked beneath and forward of. Why a mainsail's efficiency is improved with added upper roach, beyond the value of the extra area. Why the miracle of upwind sailing is not that there is so much lift but so little drag. Why, when sailing upwind, the main is always trimmed to a tighter angle than the jib. What a polar diagram tells us or why tacking downwind is almost always faster than sailing directly to a mark.There is also an in-depth look at the wonders of material utilizationnot just materials. Indeed there have been no new fibers accepted into sailmaking for over 20 years. It is how they are used that makes the difference. In the last three chapters, the authors drill down on mainsails, headsails, and downwind asymmetric and symmetric spinnakers. And in this edition for the first time they address downwind aerodynamics. The book celebrates the complexity and beauty of sails in words and pictures and of the whole rarefied sport of sailing.

Rilegato. Condizione: new. Traduzione di C. Romano.Roma, 2018; ril., pp. 168, ill.(Transiti Blu. Tecnica. 33). Questo non è "L'arte e la scienza delle vele dei vostri genitori", scritto da Tom Whidden e Michael Levitt e pubblicato nel 1990. Venticinque anni possono fare una grande differenza! Oggi esistono vele realizzate in un unico pannello, modellate sopra stampi tridimensionali, nell'esatta forma definitiva che assumeranno nel vento. I piani velici delle barche, sia da regata che da crociera, si sono radicalmente evoluti verso armi frazionati, rande square-top e fiocchi non sovrapposti. Si parte dalla storia della veleria moderna con Ted Hood e Lowell North, l'artista e lo scienziato, e si giunge ad affrontare la questione della circolazione, come nella prima edizione, ma passando per una strada diversa: tentando, per la prima volta in assoluto, una quantificazione dei suoi effetti. Perché e dove il vento, interagendo con un piano velico, accelera o rallenta. La teoria della circolazione è nota agli studiosi di aerodinamica da almeno un secolo ed è argomento di discussione tra i velisti dal 1973, quando il compianto Arvel Gentry presentò al mondo della nautica le sue teorie. Gentry era ingegnere aerodinamico alla Boeing durante la settimana e velista nei weekend. E le teorie secondo cui un aeroplano può volare contrastavano con quelle secondo le quali una barca può risalire il vento. Whidden e Levitt utilizzano spiegazioni come la circolazione per rispondere a diverse domande: Perché gli armi frazionati, le rande square-top e i fiocchi non sovrapposti hanno finito per predominare. Come e perché lo svergolamento della balumina può rivelarsi il migliore alleato del trimmer. Perché il progettista navale posiziona albero, chiglia e timone in modo tale da generare una tendenza orziera. Perché la "safe-leeward position" è vantaggiosa rispetto a tutta la flotta degli avversari. Perché il miracolo della bolina non consiste nel fatto che ci sia così tanta portanza quanto così poca resistenza. È presente un'analisi approfondita delle meraviglie dell'uso dei materiali nella fabbricazione delle vele, non già solo dei materiali stessi. Gli ultimi tre capitoli costituiscono poi una guida all'utilizzo di rande, vele di prua e spinnaker che permetterà sicuramente ai lettori di ottenere le migliori prestazioni dalle loro barche.

Hardcover. Condizione: gut. 1998. Das Standardwerk zu allen Fragen rund um das Segel: Segelfläche, moderne Segeltuche, Aerodynamik und praktische Umsetzung für Fahrten- und Regattasegler. Dieses Buch ist das Standardwerk, welches jeder Segelmacher im Regal stehen hat. Auf dem technischen Stand von 1990 ist es noch lange nicht veraltet. Whidden beginnt ohne lange Ausflüge in hunderte Jahre Segelmacherei in der Übergangszeit von Baumwollsegeln zu modernen Kunststoffasern. Anhand der Beispiele von Ted Hood und Lowell North beschreibt er die verschiedenen Herangehensweisen ans Segelmachen. Der eine mit Talent und Intuition, der andere wissenschaftlich, später mit Unterstützung von Computern. Das Computerdesign ist heute die Garantie für genaue Reproduzierbarkeit von schnellen Segelschnitten. Die Autoren informieren umfassend über die Entwicklung von Polyesterfasern aber auch Hightech-Materialien wie Aramide, Kohlefaser und Mylarfolien. Im Kapitel über Segelkonstruktion und -Schnitte wird auf die unterschiedlichen Anforderungen eingegangen, die Regattaeinsatz oder Fahrtensegeln ans Material stellen. Neben Vor- und Großsegel wird auch die Konstruktion von Spinnaker und Gennaker abgehandelt. Besonders gelungen ist der physikalische Teil. Wer sich der Aerodynamik des Segelns wissenschaftlich nähern möchte, dem sei das Werk von C. Marchaj ans Herz gelegt. Whidden versucht dem Leser die Wirkungsweise der Segel bildhaft und ohne viele Formeln anschaulich zu machen und räumt nebenbei mit Legenden wie der "Düse" zwischen Vorsegel und Großsegel auf. Somit kann zur praktischen Anwendung des erworbenen Wissens übergeleitet werden. Whidden gibt viele Tips zum richtigen Trimm und auch Pflege der Segel. Dieses Buch ist für jeden Segler, der wissen will, was seine Segel schneller macht und warum! Das Segel.
