Checking up on Doug's clear assertion (below) I find that Doug is not
correct. North say their fastest spinnaker is a radial and that 2003
Lightning world champions use them.

"For top performance and durability, we offer the R-2 and the RC-1
spinnakers. Both spinnakers are fill radial with fully glued seams for
smoothness and resistance to snags. Both are built from AirX fabric."

Tell me Doug, why did you say that they were cross cut? Are you confused
or BSing? Are you now going to take my spinnaker advice and get a faster
radial sail?

Cheers

Really? That must be why the current North and Sobstad runners on
Lightnings (and a few other one designs I believe) are all cross cut.
