STARTUP and FRANCES KINNEAR WITH 84 ILLUSTRATIONS AND DIAGRAMS LONDON JOHN LANE THE BODLEY HEAD LTD, English edition first published in 1930 PRINTED IN GREAT BRITAIN BY THE BOWERING PRESS, PLYMOUTH Foreword THE motorless AIRPLANE, i.e. the GLIDER or SAIL PLANE, is steadily growing in popularity, and is, in the truest sense of the word, the flying sport of youth. This book represents the collective results of the writers' experiments since 1921 in motorless flight, and particularly in gliding, related in a way most likely to be useful to others. In flying, more than in anything, every experience and triumph individually won by hard endeavour should be triumph and experience won for all. Its aim is to state as clearly as possible all the beginner ought to know of Gliding and Gliding Machines. Hie theories it contains are explained in such a manner as to be easily under stood. The finest airmen are often hopelessly bad mathematicians and Flying as a Sport should, as far as possible, be made easy for everybody. FRITZ STAMER and ALEXANDER LIPPISCH. -

The International Flying Dutchman Class Book
THE INTERNATIONAL FLYING DUTCHMAN CLASS BOOK www.sailfd.org 1 2 Preface and acknowledgements for the “FLYING DUTCHMAN CLASS BOOK” by Alberto Barenghi, IFDCO President The Class Book is a basic and elegant instrument to show and testify the FD history, the Class life and all the people who have contributed to the development and the promotion of the “ultimate sailing dinghy”. Its contents show the development, charm and beauty of FD sailing; with a review of events, trophies, results and the role past champions . Included are the IFDCO Foundation Rules and its byelaws which describe how the structure of the Class operate . Moreover, 2002 was the 50th Anniversary of the FD birth: 50 years of technical deve- lopment, success and fame all over the world and of Class life is a particular event. This new edition of the Class Book is a good chance to celebrate the jubilee, to represent the FD evolution and the future prospects in the third millennium. The Class Book intends to charm and induce us to know and to be involved in the Class life. Please, let me assent to remember and to express my admiration for Conrad Gulcher: if we sail, love FD and enjoyed for more than 50 years, it is because Conrad conceived such a wonderful dinghy and realized his dream, launching FD in 1952. Conrad, looked to the future with an excellent far-sightedness, conceived a “high-perfor- mance dinghy”, which still represents a model of technologic development, fashionable 3 water-line, low minimum hull weight and performance . Conrad ‘s approach to a continuing development of FD, with regard to materials, fitting and rigging evolution, was basic for the FD success. -

ABSTRACT (Maximum 200 woras) The purpose of this project was to study porpoising, one of the most common forms of dynamic instability found in planing boats. In descriptive terms, it is a coupled oscillation in pitch and heave that occurs in relatively calm water. These oscillations can be divergent in amplitude, leading to loss of control, injury to occupants or damage to the craft. The mechanics of porpoising have been studied sporadically from theoretical and experimental perspectives for many years. -
Aerated Water
Science of Sport: Sailing Can you adjust the sails to make the boats follow the tracks? Do - Think - Learn Move the sails so that the boats follow the tracks. What did you have to do to make the boats follow the tracks? Were you successful? The Science Bit The physics of sailing involves the interaction of the wind and sails and the interaction of the water and keel. To propel a sailing boat the force of the wind needs to be deflected, resulting in the boat travelling in the desired direction and not capsizing. The sails act as aerofoils which deflect the flow of the wind. The keel of the boat stops the boat moving sideways by pushing on the water. Sails propel the boat in one of two ways: 1. When the boat is going in the direction of the wind (i.e. downwind) the sails may be set merely to trap the air as it flows by. The wind pushes on the sail propelling the boat forwards. 2. When sailing towards the wind (upwind) the sails act as aerofoils to propel the boat by redirecting the wind coming in from the side and pushing it towards the rear. By Newton’s 3rd law (action and reaction are equal and opposite) the boat is pushed forwards. Also as the wind flows over the sail, the pressure difference generated by the shape of the sail results in forces on sails including drag and lift.

Lesson from Saturday = Be Big and Hike Till It Hurts, Then Hike Harder
Week 6: Lesson from Saturday = be big and hike till it hurts, then hike harder First of all, thank you to Andrew Scrivan for breaking your top section and thank you to Steve Fisk for giving him a leaky boat to use after that. Also thank you to Mike Matan for capsizing at the gybe mark in race 5. These are just a few of the many pieces had to fall in to place for my result to end up as well as it did. There were a lot of fast boats out there and most people had a very consistent day, making for plenty of excitement and close racing. I don't think anyone was upset by the postponement before racing, so good job to the race committee for keeping us out of the rain, which would have made it uncomfortable, and keeping us out of the lightning, which would have been unsafe. The breeze followed the forecast of blowing hard all morning and then picking up even more in the afternoon. Courses were another plus for the race committee. Perfect length and many fun (and stable) reaches, along with the weather mark being sheltered by the island to allow us to take a deep breath before being drowned in spray on the reaches. Thanks again. Now on to the sailing. In addition to being a tall person and incredibly fit, sail controls were exceptionally important. Before the first race, I pulled my outhaul until the hook that attaches it to the sail was touching the eye on the boom. -
