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.
