Racing yachts after dinghy's, whats the trick?

[flaming]

. I've also noticed very different spinnaker handling techniques tried by dinghy sailors on yachts.

Reminds me of a very good dinghy sailor we had come out with us. He didn't understand why we were swinging the gear, and weren't just going to do the old "chuck it round the forestay" trick... With a hundred square m kite..
