Tom,
Thank you for taking the time and going to all the trouble of providing
that
information.  I had been wondering about which end would be up after a
water
ditching in an Ercoupe.   This will certainly take some of the
apprehension
away from flying overwater.  Once again, the outstanding character of
yourself and other members of the Coupers mailing list shines out.
Spike
