Book Description
It is 1900, and 14-year-old Bertie McCross is a newspaper boy in downtown Toronto. Bertie’s family has fallen on hard times and can use every penny he brings home from hawking newspapers on the frigid streets. However, in order to do that Bertie has to keep out of the clutches of the Kelly Gang, a family of slightly older Cabbagetown toughs who are shaking down "newsies." On Christmas Eve, Bertie is almost cornered by the Kellys but is saved by Tommy Fry and Milwaukee Ed, who introduce Bertie to the thrills of iceboat racing on Lake Ontario. Soon Bertie is swept up in the fast and dangerous sport and meets a whole crew of new friends, including Isobel, a girl from a wealthy family with a mansion on Jarvis Street. The continued pursuit by the Kelly Gang, a plunge into freezing harbour water, and the clash of classes all lead up to a spine-tingling race to end all races.

Book Description
New analysis shows how Newton and Galileo provide a straightforward and useful explanation of sailing. According to Newton, the sail re-directs a mass of air of the apparent wind backwards to create a backward force (Force = ma). The reactive equal and opposite forward force pushes the sailboat ahead. According to Galileo a boat can sail downwind faster than the wind for the same reasons that it can sail upwind faster than the wind. Each tack is simply the mirror image of the other one. This is because in both situations the sailboat experiences a headwind, and the true wind is moving backwards relative to the boat. When sailing both upwind and downwind, the sail extracts momentum and energy from the true wind by slowing it down. That's it.

Book Description
An estimated 4.1 million people in the United States participate in recreational sailing. Yet the large library of sailing literature leaves many of them high and dry. On one side are technical guides for America’s Cup boat-builders; on the other, simplistic books for weekend sailors with little interest in science. In Float Your Boat! professional and amateur boaters alike will find intelligent and understandable answers to such questions as: What were the key innovations that made sailboats more efficient? How do you increase the speed of a boat? How do sailboats travel into the wind? Why are so many explanations of sailing so wrong? Sailing enthusiast and physicist Mark Denny first traces the evolution of the sailing craft, from prehistoric coracles made of animal skins and antlers to the sailboat’s reinvention as a pleasure craft during the Industrial Revolution. He then identifies specific sailing phenomena—how wind drives modern Bermuda sloops, how torque determines stability, why hull speed exists—and provides the key physics principles behind them. Whether you are an inquisitive landlubber who has never set foot in a boat, a casual weekend sailor, or an old salt who lives for the sea, Float Your Boat! is an accessible guide to the physics of sailing.

Book Description
The groundbreaking reference on high speed racing techniques--the bible for racing sailors of all levels and abilities from dinghies to the America's Cup. High Performance Sailing has become the standard reference work on high speed racing techniques. Groundbreaking in its thinking on boat speed, strategy and tactics, and timeless in its application, this second edition has been brought right up to date with new information, the discoveries from new boat testing and new developments. Some people like to sail. Some people like to sail fast. This is a book about sailing faster. During the past few decades there has been a revolution in the way some boat designers and sailors have thought about, designed, built and sailed their boats. This book is about the new ideas which have led to these greater speeds and the faster sailing techniques which have been developed to achieve them. "It is the cheapest bit of go-faster gear you can buy..."--Robert Lloyd, Island Sailing Club "One of the most readable books on the complex subject of sailing faster, and without doubt, a must for every racing sailor"--Yachts and Yachting

Book Description
The mixing-layer height and the average wind speed within the mixing layer were calculated twice for each day of a 5-year record of upper air observations at 62 National Weather Service stations int he contiguous United States. The times of day of these calculations are morning and mid-afternoon. A rough allowance was made for effects of the urban "heat island" on the morning mixing heights. The morning and afternoon times coincide approximately with those of maximum and secondary minimum concentrations of slow-reacting pollutants in cities. These calculations illustrate the typical large diurnal variation in atmospheric dispersion. Twenty charts present seasonal and annual, and morning and afternoon mean mixing heights and wind speeds. A model of some general dispersion features over urban areas is described in which the normalized pollutant concentration averaged over a city is a function of mixing height, wind speed, and city size (distance the wind travels across the city). Frequency values of mixing height by wind speed are used with the model to calculate average normalized concentration frequencies for each weather station. Thirty charts present isopleth analyses of seasonal and annual, and morning and afternoon normalized pollutant concentrations that were exceeded 10, 25, and 50 percent of the time for specified city sizes. The occurrence of episodes during which upper limits on mixing height and wind speed were not exceeded were determined from the daily morning and afternoon values of these parameters. Isopleths of the total number of episode-days for episodes lasting at least 2 days and at least 5 days with various limiting mixing-height and wind-speed values are presented in 20 charts.

Book Description
Here is a detailed study of the motive forces of a yacht written in clear and accessible terms. The author has the rare gift of enabling his readers to relate the nautical phenomena with which they are so familiar to a scientific explanation of how and why these occur. The first part covers downwind sailing, upwind sailing, sails, the hull, and the dynamic motion of a yacht. Part Two is devoted to more mathematical explanations of the same phenomena for those requiring a more scientific approach.

Book Description
'Monumental!' - Bob Ross, Australian Sailing High Performance Sailing is now regarded as the bible of racing sailors and carries a string of endorsements from high achievers. Since its publication in 1984, racing yachts and dinghies have developed out of all recognition - a new high-tech breed of 'apparent wind' fast racers has claimed the water and so far no-one has applied themselves seriously to analysing what makes these boats sail fast (and what will make them faster). This is Frank Bethwaite's ground-breaking achievement in Higher Performance Sailing. By means of extensive research, and working with sailors of different racing calibre, Bethwaite analyses how to harness the apparent wind for increased speed and better position on your rivals. Higher Performance Sailing will provide the key to racing sailors' dreams. Praise for Bethwaite's High Performance Sailing: 'It represents a breakthrough...It is a book that my Olympic squad will benefit from.' Rod Carr, former British Olympic Sailing Team Manager 'Allowed only one "if only" in yacht racing, it would have been to have read Higher Performance Sailing years ago.'
