Question I have asked before, and will ask again. Why are the Mosquitoes being considered as F16s when there is a large difference in their VYC handicaps to an actual F16 handicap? 71 to 79.5 is a big difference. I note that in the results above you have adjusted for placings over the line and that the Taipan didn't win every race. But your description of the wind conditions probably explains this. However, we aren't really comparing too like boats in a formula class. For me it detracts from the F16 concept. Just my 2 cents.
The Mozzies aren't being considered real optimized F16s, just grandfathered F16s. They are being included because if they weren't, there wouldn't be an F16 class in Australia (or South Africa either). As you can see from the results, it wouldn't have been much of a race without them.
Until recently the Mosquitos and an occasional Taipan 4.9 were the only F16s in Aus. Then Gary built "Altered" and a few more Taipan4.9s started using spinnakers. Now the Cobras have joined in as well (with a handicap slower still than the Mozzies, if you're worried about the handicap).
In Australia we still don't have anyone manufacturing F16s (although two builders say they are "close"). That's what's really detracting from the F16 concept here.
