Humpback whales - a source of new aerodynamics?

suffer in the rain.


What other gliders are known to have this problem with
water or turbulent air? Seems I have heard that one
of the ASW series was similarly affected.

Another possibility that I recently heard about that
might help
increase our L/D: It seems that marine mammals may
shed microscopic
amounts of their skin as the swim, disrupting the
normal boundary
layer turbulence. I guess a whale that uses Head &
Shoulders Shampoo
will not swim as fast as the others?

Anyone else hear of this theory? Or think I was being
ribbed? Or have
any thoughts on how it might be used in sailplane
wing designs?
