Welcome to Navel Gazing at Camp David Shorts. In this fascinating short, we delve into the intricate physics that allows sailboats to seemingly defy the wind by sailing upwind. How is this possible? It's all about understanding the fundamental principles that govern sailing dynamics. From the Bernoulli principle to the concept of apparent wind, we'll break down these complex ideas into easy-to-grasp concepts. Whether you're a sailing aficionado or a curious mind, this short will give you a glimpse into the art and science of sailing. For those of you looking to expand your knowledge, consider reading 'Sailing for Dummies' by J.J. Isler and Peter Isler, Wiley, published in 2017, which provides a beginner-friendly guide to all things sailing. Alternatively, 'The Physics of Sailing Explained' by Bryon D. Anderson, released by Sheridan House in 2023, offers a deeper dive into the scientific aspects that make sailing possible.

► In Cape Town, where the largest production center of sailmaker Ullman Sails is now located, we discovered not just one sail-loft floor, but five or six! However, the story didn't begin in South Africa: it was in Newport Beach, California, that David Ullman, at the time aged just 21, built his first sail loft. The year was 1967. 12 years later, a second site was opened in Dallas, and growth continued throughout the 1980s and 1990s. Today, Ullman Sails is represented in 25 countries and has 75 sites. The largest of these is in Cape Town, South Africa, and this is the one we got to visit. There is a staff of 120, and sails of all materials are made here. There's one workshop dedicated to the manufacture of FiberParth membranes. It's also on these floors that the sails for the Leopard range - and many other catamarans built in South Africa - are made. Over the past 30 years, more than 100,000 sails have been produced here! The sailmaker is also diversifying its activities with a clothing range, Six Seven by Ullman. ► Become a FREE SUBSCRIBER to Multihulls World's YouTube page now - https://www.youtube.com/c/MultihullsWorld ► Log on to our website to discover over 500 multihulls tests!
