{"product_id":"the-evolution-of-planing-sailboats-john-macbeath-watkins-9798685749901","title":"The Evolution of Planing Sailboats","description":"This 38-page monograph delves into the origins of the planing sailboat, from the discovery of the uses of hydrodynamic lift in the early 19th century to the shapes evolving today. I prepared it with help from an international group of sailors and naval architects, and I welcome further input for possible future revisions of the text. The only illustrations not done by me are at least a century old. I leave to others the granular histories of various racing sailboat classes, and attempt only to trace the history of planing sailboats as a type -- the ideas behind them and the evolving understanding of what makes them fast.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e John Macbeath Watkins\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 8685749905\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9798685749901\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Independently Published\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 09\/13\/2020\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 40\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.15lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 9.02h x 5.98w x 0.08d","brand":"John Macbeath Watkins","offers":[{"title":"Paperback","offer_id":43943507132671,"sku":"9798685749901","price":7.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/products\/img_5ffd6cdb-dadb-43d5-8459-c475916f17fb.jpg?v=1681498502","url":"https:\/\/www.whiterainbookhouse.com\/products\/the-evolution-of-planing-sailboats-john-macbeath-watkins-9798685749901","provider":"WR Book House","version":"1.0","type":"link"}
