Abstract: A multi-adjustable watercraft chock includes a base having opposite ends attachable on a surface, a pair of arms pivotally connected at inner ends to the base at opposite locations proximate the opposite ends of the base, contact bodies disposed at outer ends of the arms, couplers connecting the contact bodies with respective outer ends of the arms so as to define a pair of pivotal axes spaced apart from, and orthogonally oriented relative to, one another such that one contact body is pivotal in orthogonal directions relative to the respective outer end of one arm, and angular adjustment mechanisms coupling the arms to proximate the outer ends of the base so as to enable the arms to be continuously angularly adjusted to selectively extend from the base in oppositely flared configuration and arm outer ends and therewith bodies to thereby raise or lower relative to the base.
