Planing hulls have a flat bottom, and the sides come up from the bottom at a defined angle. When at rest, or when paddled very slowly, planing-hull boats plow through the water. When the boat is given some speed, the flat surface skims to the waterâs surface, and allows the boat to spin with less effort.

The most recent change, from 49 stars to 50, occurred in 1960 when the present design was chosen. When we look at the history of the U.S. flag from 1777 to 1960 there were 27 versions of the flag with 25 of those changes due to the changing number of stars.
