Info Navtec Case Study: Windrose   Current Case: Windrose Challenge: To design and produce the rigging and components for this new yacht with masts and booms built by Carbospars in Palma de Majorca. Stability, weight and aerodynamics played an important role since the yacht will race the 2002 Transatlantic Challenge. Yacht Design: Gerard Dijkstra & Partners Yacht Specs: The yacht is 152 ft in length, has a beam of 26.3 ft, draws 26.3 feet and displaces +/- 145 tons. Shipyard: Holland Jachtbouw, The Netherlands Navtec Rigging: Nitronic 50 and components. Windrose is a modernized classic of sorts with her traditional styling and grace, but with thoroughly modern engineering and equipment including a keel bulb, mast truck and carbon spars. The yacht was designed by Gerard Dijkstra with two almost opposing purposes in mind; one, to race the 2002 Transatlantic Challenge, trying to break Atlantic’s 1905 record, and second, to be a luxury charter yacht. Navtec was approached by Cees Ren of Holland Jachtbouw to design and produce the rigging for Windrose in close cooperation with Carbospars in Palma. Navtec measured all of the chainplate offsets and, using AutoCAD, calculated all of the rigging lengths. Before the manufacturing of the rigging began, the drawings of each fitting were e-mailed to Carbospars in order to verify tolerances. Navtec’s engineers in Guilford, CT worked with Carbospars to optimize the asymmetrical toggles, which are used to attach all of the diagonal stays and runners. Once the rigging was completed, it was shipped directly to Holland Jachtbouw and fitted to the masts. Under the direction of Project manager Jos Scholten, Navtec personnel and Holland Jachtbouw’s riggers then stepped the masts and set the rakes to the design specifications of Dijikstra and the close tolerances mandated by the shipyard. With the coordination of all involved, the rigging fit perfectly and the stepping and sea trials were a success. Windrose, who is currently sailing in Antigua, is preparing for the start of the New York Yacht Club’s Transatlantic Challenge from New York to the Needles scheduled to start on May 18, 2002.
