According to my previous plan from 2002 that is at 551 mm from the bow: http://www.anderswallin.net/wp-content/2002_05/noux_layout_2002may05.pdf Hi Luciano,

I have a question about fin-bulb: could you give me the exact position where the C.G. of the bulb has to be positioned on the fin. Many tanks, Regards, Luciano Hello Anders, I’m Luciano from Milan , I’m building boats Noux-2 following your project (NOUX 2 Preliminary layout plan 2006 Feb 15 Anders Wallin).

The Sails ETC boats use a fixed mast position, but the fin position can be adjusted forward and aft by cutting the fin to suit the finbox in different ways. With the Noux we did it the other way around: the fin is fixed, and the mast can be moved forward and aft by about +/- 10 mm. We're hoping that will give us enough room to experiment and find out the best tune for each rig and wind condition. We made the hole rectangular, 5 mm wide, so that the amount of ballast water that the hole carries with it would be a bit reduced from the amount it would be if the hole would be oval and 12mm wide. To fit the mast to the hole we're fitting a piece of 10x5 mm aluminium to the end of the mast. At least that's the plan right now. Anders Hi Alexander,
