We dismantled and put the Tornado in storage last saturday. Had a really nice sail first with plenty of wind, probably the hardest wind we have seen the whole season. New spi was a bit scary, loads of power..
I suppose the season has ended in Oslo as well, even with the forecast you have for an unusual mild winter?

Isn't the NACA63A010 a laminar section? If so, it has a theoretically better polar than the NACA00xx series, but it must be buildt to very high accuracy and the surface must be very good. In addition, there is doubt wether the daggerboards on a beachcat ever see laminar flow, so a non-laminar section might be just as good..
If you want a short primer in how to run the XFLR5 software, just give me a call. Running it is not hard, but setting it up and interpreting the results is what demands some theoretical knowlegde.
