Abstract
A paddle construction for watercraft applications, engineered to efficiently provide thrust and reduce form drag with other advantages inherent to the structure. The paddle has a means of actuation and a body. The body has at least one leading edge, at least one trailing edge, and at least one chord extending between the leading and trailing edges. The body has at least one thickness that varies along the length of the chord(s) from the leading edge(s) to the trailing edge(s), and therefore has at least one maximum thickness. The maximum thickness is located closer to the leading edge(s) than the trailing edge(s). This construction provides for at least one body portion tapered from the area(s) of maximum thickness to the trailing edge(s) to reduce form drag during use.
