Phanchita Supasirithanawat (www.rcsails.com) from Bangkok Thailand sent me these pictures of a down-scaled Noux design built to the RG65 rules. It’s called a Noux65.

There is a video here http://www.rcsails.com/noux65.htm

Another view of the spray-painting setup.

The bulb is home-made, cast in a plaster mould.

Here is Steinar’s first boat, now completed and painted. I posted some building pictures earlier here and here.

Steinar asked if there is a Noux-logo. Sure! I just need to post it online in some common format. Stand by…

Steinar from Norway wrote to tell me about his Noux project. He started out building a planked wooden Noux (above), but it ended up too heavy, so instead a wooden plug was made (below)

Using this plug Steinar has now made a mould and moulded a few glassfiber Noux hulls. There’s no standard deck solution for the Noux yet so Steinar has invented his own, with a central round hatch for access to the electronics.

Boris from Switzerland sent me these two pictures of his Noux project which he has just started – thanks !

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

Peter: “ Glassing the balsa with West System epoxy was easy. Final weight of the boat with all deck fittings in place and a bit of paint – 612 gms – well within budget. The whole shell of the boat including the foredeck is just so stiff and strong – 3mm balsa over shadows – pre primed inside and out with Wests diluted 10% with MEK (Don’t tell Mr West – they don’t approve but it works so well over balsa) – then 3oz satin glass cloth on the outside using full strength West and 3/4oz glass cloth inside with 5% MEK dilution”

“ Realising why the foredeck overlaps the cockpit – to provide a place for the mast ram – I had cut 50mm off the cockpit balsa moulding and then had to add the extra 50mm back in 0.6mm ply – while difficult it proved to be very strong and so eliminated the need for deck beams to hold the mast and keel box.”
“ Drilling the holes for the winch – the tolerance between screws and centreline of the pulley axel are very close – I ended up making a template and drilling through it”

The plaster bulb mould ready for pouring. “The name FAT NOUX comes from the extra in the beam and the thickness of the keel – I poured the keel lead and it had to happen – FAT keel – 2.5 Kg out of the mould so a lot of shaving with the wood plane and its down to the budget figure on your web site.”

Boom and vang fitting with ball races – works so smoothly

Nice looking laminates ! I am hoping to receive a detailed report from the builders on how these were done, i.e. plug treatment (release agent), gelcoat, layers of fiber, resin etc.

Here is yet another deck design for the Noux. This is the plug for the deckmould shown above. I am told the idea was to minimize the volume of the cockpit and thus minimize drag related to water carried in the cockpit in heavy weather.

Rumors say that Wallin&Ginström are planning to build a deck (cnc milled plugs ofcourse!) in the near future according to the original Noux 2 plans – but you never know… stay tuned!

The hull being planked with 4mm balsa. Peter didn’t reduce the shadows from the plan before planking so the boat will end up a little bigger than designed – a Fat-Noux

The cockpit deck, also planked in balsa.

Peters novel idea for a homemade fin, covered in wood ofcourse – true to the style of the boat !:

“3 -6mm carbon tubes sanded down on two sides a bit and glued between 1mm ply skins with balsa packing the spaces – all soaked in West Epoxy and clamped between full length temporary balsa formers. It has turned out with all the necessary stiffness even before I glass it.”¨

Looks good, my only concern is that fin thickness is a critical parameter for performance so the homebuilt fin must be around the same thickness, 6-7 %, as a full-carbon fin. With a chord length of 85mm this means a thickness of only around 5-6mm.

The finished fin with the rudder. The rudder requires less stiffness so it has a plywood core with balsa outer skins covered with glassfiber cloth.

More to follow later hopefully…

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
