    • A push pole for propelling a boat comprising an elongated straight pole having a first and second end and a foot extending from the second end of the elongated pole. The foot consists of two prongs where the first prong extends coaxially in relation to the elongated pole and the second prong has an arcuate shape disposed towards the first prong. The first prongs has a spiraled configuration between a spade-like terminus and the elongated pole. The second prong has a spade-like terminus. The configuration of the foot provides for efficient insertion and release of the prongs from the floor of a waterway.
