Holland Jachtbouw To Launch 'J8' In a Few Months She is just a couple months from launching, in the Spring of 2015, J8, a J Class from the drawing board of Hoek Design. The fast sailing yacht is based on the original lines and plans from Frank Paine in the 1930s. This latest addition to the J-class revival is set to rewrite the history books in terms of performance according to a special software program devised by Hoek Design that has been able to compare all the J designs from the 1930s. It has calculated that J8 was to be the best in terms of performance, given her reduced wetted surface and highest keel aspect ratio in comparison to the other Js. Furthermore she is designed with the longest waterline length.
