We derive very simple compact equations for unidirectional gravity water waves. For such waves, as it is well-known, the coefficient of nontrivial four-wave interaction is identically zero. This fact allows essentially to simplify
the Zakharov equation applying a canonical transformation. Obviously this transformation is not unique. We suggest a specific form of such transformation that allows to derive a remarkably simple form of the Zakharov equation. One can name it as the super compact equation. This equation is very traightforward and includes nonlinear wave term (\`{a} la NLSE) and advection term (may describe pre-breaking wave). Moreover, this equation allows also to derive spatial version of water waves equation which can be used to describe experiments it the flume.
