Why must a boat make leeway in order to sail to windward?  How can a helmsman prevent downwind rolling?  Why is a sail able to produce a force at right angles to the wind direction?  These and many other important questions are addressed by the authors in this detailed study of the motive forces of a yacht. 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.\u003cbr\u003e\u003c\/span\u003e\u003c\/p\u003e","brand":"Rarewaves","offers":[{"title":"Default Title","offer_id":41048909676641,"sku":"9781574090000","price":29.58,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0092\/7504\/8033\/files\/b9d1d978836763784e95202ed22c2c28.png?v=1698283821","url":"https:\/\/www.rarewaves.com\/products\/9781574090000-symmetry-of-sailing","provider":"Rarewaves.com","version":"1.0","type":"link"}
