There do not appear (in P15 1618) to be any tie-downs or other devices
to reduce the upward force on the cockpit seats, where the tubes would
be placed. When inherited, the flotation material on Little Dipper
was secured only to hold it aft. As long as the tubes are not
over-inflated... there should be no structural issues.

Don't mean to cut off dialogue, though. I still have a lot to learn
about this little beauty, and hope to hear from someone who has
actually tried the inner tube idea.
