The Internationals Nacra15 Class Association has posted the following Notice on it's website (http://www.nacra15class.com/notice-board/) regarding daggerboards and rudders: 19 June 2017 : use of non-class legal daggerboards and rudders Due to a delay of the delivery of new original Nacra 15 rudders and daggerboards, some new boats are delivered by Nacra 15 factory with temporary other rudders and daggerboards (original from Nacra F16 or Nacra 17). Sailors with a new boat with non original Nacra 15 rudders and daggerboards are allowed to use the temporary rudders and daggerboards delivered by Nacra factory until the original parts are delivered by Nacra. As soon as the original rudders and daggerboard are delivered it is for a boat owner/sailor not longer allowed to use the temporary rudders and daggerboards. During use of temporary daggerboards the maximum depth of the boards must be the same like the original Nacra 15 daggerboards. On behalf of the Inernational Nacra 15 Class Association, Edwin Lodder (Class Manager) Paul Wakelin (Chairman)
