A watercraft includes a molded hull in the form of a single-piece hollow plastic structure, and the hull defines a recess having an interior. An insert is also provided that defines an opening and is attached to the hull. The insert is positioned with respect to the recess such that the opening in the insert communicates with the interior of the recess, and the insert cooperates with the recess to define an undercut that accommodates a portion of a hand of a user.
