Claim 7:
8. A method for use of a paddle board by a user in water, comprising the steps of:
manually turning a pair of crank pedals connected to a drive shaft of said paddle board;
rotation of said crank rotating a rotatable housing, said rotatable housing connected to said drive shaft, said rotatable housing comprising an outer surface circumferentially surrounding said drive shaft;
rotation of said rotatable housing driving a set of paddle wheel blades connected to said outer surface of said rotatable housing;
a first paddle wheel blade, of said set of paddle wheel blades, pivoting on a hinged connector, said hinged connector affixed to said outer surface of said rotatable housing, said set of paddle wheels positioned radially outward from a center position between said pair of crank pedals;
rotation of said first paddle wheel, indirectly powered by said step of manually turning said crank, propelling said paddle board forward; and
pivoting said first paddle wheel blade about said hinged connector, said step of pivoting alternatingly folding a radially outer edge of said first paddle wheel blade inward to a first radial distance from said drive shaft and unfolding said radially outer edge of said first paddle wheel blade outward to a second radial distance from said drive shaft, said second radial distance at least five percent greater than said first radial distance.
