**Abstract:**

In earlier talks, we have heard about three-dimensional water waves for which the velocity field *U* is Beltrami. That is, where \(\nabla \times U\) is colinear with *U*. Inspired by an approach used by Lortz (1970) in the context of magnetohydrostatics, we construct small symmetric doubly-periodic gravity-capillary waves with a non-Beltrami velocity field.
