Most likely he called it an Airelion(sp?) but it's a really just a cool
trim tab no matter what you call it.

The best thing about a Ketch is it's ability to balance..... has to be
better than any other sail configuration, not that I have that much
experience in other sail layouts.

Once I trimmed RedCloud so fine, I thought I engaged the auto pilot
and found out 2 hours later... still on course ....I forgot to engage
the autopilot clutch. :0)
