1. A hydraulic piston spud pole for anchoring a vessel, comprising:
a) an elongate sleeve configured to be affixed to a vessel and having a top, a hydraulic inlet, a bottom terminating in a bottom aperture, and a vertically-extending inner surface having a first inner diameter and provided with a sleeve bearing having a sleeve bearing inner surface having a second inner diameter that is narrower than the first inner diameter;
b) a spud pole vertically-movably seated within the elongate sleeve and having a vertically-extending outer surface configured to fit closely against the sleeve bearing inner surface, and having a piston with a piston outer surface configured to fit closely against the vertically-extending inner surface of the elongate sleeve, wherein a hydraulic column communicating with the hydraulic inlet of the elongate sleeve is at least partly defined between the vertically-extending outer surface of the spud pole and the vertically-extending inner surface of the elongate sleeve; and
c) a pump assembly comprising a pump, a pump inlet line connecting the pump to a source of water, and a pump outlet line connecting the pump to the hydraulic inlet.
