The gang are off for a ski trip to NZ, specifically Mt Ruapehu, starting this weekend!
Markla and Nessie should be taxiing now with the rest of us stragglers coming in waves tomorrow.
Wish us luck and no broken bones...

wings
i did up a drawing of the wings on my boat for reference to the new slino. this drawing is available thru my google docs (i will gradually transfer all of my drawings to this site - still not sure where to put the rhino model and cad files, for now these can be emailed on request).
at the moment I am running aluminium wings as noted on the drawing. i also did some calcs for equivilent carbon wings (based on CST products):
76x1.27 Aluminium (EI 14.37kN/m2)
*ID63x1.8 Carbon
50x1.6 Aluminium (EI 4.92kN/m2)
*ID35x2.5 Carbon
ID40.4x2 Carbon
ID44.7x1.8 Carbon
ID47.2x1.5 Carbon
40x1.6 Aluminium (EI 2.46kN/m2)
ID32x1.5 Carbon
*ID30x12.6x1.5 Ellipse Carbon
As drawn in aluminium the wings would be approx 7.47kg
Using the alternative carbon sections marked with * above gets 4.72kg
A bugetary price for aluminium tubes is $266, for carbon $1873 (again using the * sections)

new slino
i can't remember when but I sold the jig-mould-thing to a guy in melbourne and gave him some cut files so he could build a boat like mine. i just got some photos of his progress and they are attached.
gotta love the stealthy look.
more details as they become available.

plug 2
while in the mood for plugging reasonable looking companies I can across a guy (when they let me out of my exhibit) at the Sanctuary Cove Boat Show selling this stuff:
Hull speed super glide
http://www.hullspeed.us/hullspeed_products.asp#superglide
It looked rather neat. Very easy to apply, just use one of these basic spray bottles to apply to the surface and then give a circular wipe with a clean white rag. Being a 2 part system it will cure on the foil surface and is good for up to 3 months. It does not need to be buffed like a polish system, just wiped into a thin film.
It looks ideal for foils and apparently olympic dinghy teams are using it. Anyone else tried it?
From Phil @ Dulon...
$195 per quart kit and that would last you until you are grey and unable to race moths I should think!

Rapid Prototype
For the last few weeks I've had a Bladerider RX to play with. It has undergone a little bit of minor damage (standard fare for a moth) including busting a plastic spreader base fitting. With no success reaching BR, I tried my hand at something I've wanted to do for awhile...RAPID PROTOTYPING.
Some basic rhino modelling and a couple of ridiculous quotes later ($100s), shapeways came to the rescue. $11.70 for the part, but minimum order of $25(ish) and 10 days later my two spreader end replacements have arrived!
The broken spreader end, the model and the final part.
The material is what they call white, strong and flexible and now that it is in my hand, it seems just about right.
So if you've got no time, tools or skillz for building some small fiddly bit, give rapid prototyping a go. If you've got no modelling skillz, let me know and I can probably whip something together for you (within reason).
Must resist the urge to pimp the boat, but if there is enough interest for certain items I may consider stocking some bits and pieces.
Aside - They can rp metal, glass and sandstone as well!!! Unbelievable stuff!
Disclaimer - I have no affiliation with shapeways, my experience is that their service and price have been really good, so they deserve a plug.
