Prototype finbox for Noux

Tuesday, November 14th, 2006

Although we’ve already built a number of finboxes, I’ve forgotten to publish the plan - so here it is. As the Noux Mk2 is still somewhat of a prototype this finbox has a long 27.5 x 5 mm slot for the mast which will allow optimisation of the best mast position and rake angle during testing. So as not to carry a whole lot of extra water in the boat we made the mast-box narrow, 5mm, which means that the lower end of the mast needs to be an aluminium extrusion of 5mm width… A future Noux Mk3 might again have a more traditional mastbox for a round mast when we have found the optimal position.

Noux Reduced Shadows

Wednesday, October 4th, 2006

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

RC-Pot recess for Noux

Friday, September 29th, 2006


I’m really happy that we now have the whole chain from drawing (far left), into CAD/CAM and cnc milling (middle left) making high-tolerance (well, almost…) parts (middle right), which can be used as moulds for Noux components (far right). With some effort and determination you can now go from concept drawing to finished part in one weekend.

Radio installation plans

Sunday, August 27th, 2006

Some plans and ideas for the Noux mk2 radio installation. We are using a ca 116mm diameter food container lid and rim as the only deck hatch. We want the winch, batteries, servo, and Rx, all accessible through this hatch.

Update 2006 Aug 30: A variation on the same theme: a “flat-pack” version.

Noux 2 layout plan and 3D IGES file

Wednesday, March 8th, 2006

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

Friday, December 16th, 2005

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.

IOM Hull Hydrostatics

A bit of hydrostatics data for some hulls I happen to have in my CAD program.

Simple Bulb Design

Sunday, June 5th, 2005


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”.
