Abstract:
A manually propelled personal floatation apparatus comprising:a body capable of being buoyant in water and having a front, a back and two transversely opposed sides; and a propulsion structure pivotally coupled to a side of the body with a pivoting structure and having an elongated rod member with an upper portion and a lower portion, each portion being moveable between forward and rearward positions relative to the body, and a fin member pivotally coupled intermediate the upper and lower portions and adapted to extend substantially perpendicular from the body when the lower portion is moved from the forward position to the rearward position and lay substantially parallel to the body when the lower portion is moved from the rearward position to the forward position; wherein the body is propelled in a substantially forwardly directed vector when the lower portion is moved from the forward position to the rearward position caused by water resistance acting upon the fin member when the fin member extends substantially perpendicular from the body.
