Noux Reduced Shadows

I've had a couple of requests for reduced shadows for the Noux by people wanting to home-build the boat using planking or other methods. Here are the lines with 1-6mm offset from the outer hull surface. A DXF file is attached to the pdf, click the small paper-clip next to the text to save the DXF as a separate file

Ninja, a Marblehead by Henry Ericsson

A building guide for the "Ninja" Marblehead in 4 parts by Henry "Heffe" Ericcson. Published in Pienoismalli in 1988.

During the 80-ies it was still possbile to home-build a competitive Marblehead. The article describes the planking process, radio installation and rig building. An unknown number of these were built and raced in the 1990-ies, the most visible ones being two beautifully planked wooden Ninja's by the Purhonen brothers.

A nice example of how an article series can have a positive effect on the class in a country. A comprehensive guide starting from scratch building the hull and ending with tuning the boat and racing rules/tactics. We definitely need something similar for the IOM class ! (something along these lines is where I want to take the Noux concept - if and when I have time...)

This series later also appeared in the Swedish Allt om Hobby magazine. (If anyone has that article series I could publish it here also!)

Noux 2 layout plan and 3D IGES file

An updated layout plan for the Noux-2 with the winch placed under the foredeck and a circular theme for the hatches.
There's also been a request for a 3D IGES model for the Noux-2 so here it is.

Update 2006 May 03: Hsinli Liu ponted out some problems with the previous IGES file. I have made a new one which should be at better resolution: Noux2_2006may03.IGS

Rudder design for Noux IOM

Finally decided to make some proper rudder moulds for the Noux. This design, based on the rudder a number of Noux boats have been using for 1-2 season, was chosen. It's a simple(based on a Marblehead rudder by Bob Sterne actually) moderately deep rudder with a fairly thin section (just enough to accomodate a 4 mm rudder stock).

Below some pictures from the CNC milling of aluminium moulds.

Simple Bulb Design

Since publishing the bulb mould plans there has been a couple of requests for a drawing of only the bulb. Here it is. It's a round cross section 350mm long NACA 0010-34 bulb.

I'm using a feature of Adobe Acrobat 6.0 to attach a DXF version to the PDF file. Open the PDF in acrobat reader and access the DXF by right-clicking on the paper-clip on the right and choose "save embedded file to disk".

Laerke IOM by Søren Andresen

drawing in DXF format

Søren Andresen (DEN) sent me the plans for his own design with which he won the 2005 Nordic Championship and placed 2nd in 2004. He also sailed it into 35. place in the 2004 Euro Champs in Arcos/Spain.

The PDF file contains the sections and a drawing with the mast and keel positions but you should really download the DXF file and printout accurate sections with a CAD program if you want to build the boat.

IOM Bulb Mould plans

Update 2015-03-01: by popular demand, IGES files for the top and bottom bulb mould. Use at your own risk.

  • bulb Dated 2003-05-01. If you don't have a CAD program that opens these, you can use an online IGES viewer to view the files.

Our bulb moulds are CNC milled from aluminium and more than 15 bulbs have been made successfully from them.

Note that it could be useful to make the hole through which lead is poured in a little larger than shown on the plan.
