Description
This
web site is dedicated
to wing developement for use on dirt and iceboats. We have created some
plans from several previous sucessful wings to create a small, simple,
and
inexpensive wingboat called the ST 49. Check in the files section under ST 49 drawings for detailed drawings of my ST 49. We have made up some box rules for the ST 49. See files section under ST 49 design rules. The rules allow for open design with some limitations to the boats size and wing area. A couple design parameters allow the boat to be very simple, easy to transport, setup and affordable to build. This boat could be raced as a landsailer in the Nalsa open design class 5 class. There is an opportunity to race as iceboats too. I have spoken with Paul Krueger about racing wings in the ISA. He said they wouldn't allow a wing to compete in skeeter class but if we entered 3 or more wings they may consider a separate skeeter class just for wings. John Eisenlohr US 772

Re: Aspect ratio and rake
I should never have asked the first question. I haven't been able to think of a simple way to state the rule, or show it in a picture, in a way that would

Re: Aspect ratio and rake
Will, I measured leading edge. Top of fence to bottom of base = 192 exactly. No closure plate. The only issue I see is how to measure with a radius on top or

Re: Aspect ratio and rake
As I see it the idea of a fixed maximum measurement on the leading and trailing edges gives the height rule clarity that can't be interpreted any other way.
