Someone just posted this link on the Spencer Aircar Yahoo Group.

WHAT DO THEY ACCOMPLISH?


1) Shorten time to mount the bow wave by 6 seconds;
2) Shorten time to take off water by 5 seconds;
3) Eliminate water spray damage to the propeller;
4) Provide a convenient platform for entry or disembarking;
5) Improve cruise speed by 7 to 10 mph.

I understand the first 4 results but what is the science behind the increase in cruise speed?
