[C320-list] More on Genoas

[Dave Moores]

Questions for the racers - my current genny tacks to the stemhead not the
drum.  Rationale is deck-sweeper is better, air can't flow under the bottom
of the sail etc.
 
Do we believe this?  After all, that bottom foot of the sail is in pretty
disturbed air anyway, so would I lose much performance by having my new sail
attach to the drum, not the stem?
 
And for those who attach to the drum, do you furl or drop when you put the
spinnaker up?
 
All important questions!
