Abstract
A shallow water anchor is provided. The shallow water anchor comprises a first anchor extension and a second anchor extension axially received by a housing. The first anchor extension is axially received by the second anchor extension such that the first and second anchor extensions are sequentially deployable from the housing an actuation arrangement. The actuation arrangement is controlled by a control interface that is operable to detect when the shallow water anchor has reached a fully extended state and fully retracted state. The shallow water anchor further includes a biasing compensator that compensates for fluctuations in the overall depth of water the anchor is deployed in due to waves or other anomalies.
