Salty , do you still have the template for the foiled rudder, or someone ?
i want to do my foiled rudder,and i need the template for 0012
i did a long search google last night ,but i couldnt find any place i can print out the template
thank you
Gabriel
Gabi--I have one that is the right size for a CP19. I'm afraid it won't work for you as the chord depth on either rudder are quite different. The CP19 is almost twice the weight thus the rudder is both longer and wider.
Not sure what search engine you're using, but here's a site with the shape listed as well as the calcs leading up to the shape.

Another site with information you need to know to proceed: http://www.boat-links.com/foilfaq.html
If all fails, send a private message to Doug142..pretty sure he has the template you need or can make one for a nominal charge.
You know Gabi, I bet if we used a copier and shrunk down the shape of my foil to match your chord depth, it would work. If one had a copier that could reduce by 1% increments, that may just be the ticket.
Any second opinions on this?
Lemme know if you want a tracing of the larger shape. I could probably scan it and email it to you and let you tinker with the size.
thank you salty,
i think i figured out how to use those charts you gave me on the link, ...it just all looked like the sanskrit alphabet at first,but im prety sure i got the hang of it now
ill try to trace the shape from the coordinates and if it doesnt work ill let you know,
thank you
