projected area (0.565) of an inflatable sled*. You can use the same 12/7 or
7/12 or 0.58 factor of the flat area of an ARC, because they FEEL like they
have about the same projected area for their flat size (only the
manufacturer's projected specs don't agree with this, but that really
*the difference likely due to the foil's projected being a few percent less
In other words, if you don't want to do the calculations you can compare
foils & INFLATABLE sleds using both their real projected areas (from column
D of my chart), but don't use that for ARCs (use Hung's 7/12, or 12/7).
