"rolling" movement of the vessel from side to side; it tips to the left, then the right. Most cookers are hard to use in these circumstances as the gimbals, the pivots they rest on, cannot compensate the degree of movement and spill the boiling contents of the pans on the cook's legs, or worse.
No emplear la cocina cuando se espera fuerte balanceo del barco.

DRAE
balance
6. m. Mar. Movimiento que hace la nave de babor a estribor, o al contrario.

Résumé / Abstract
A detailed exposition of the kinematics of the transverse plane motions of ships is provided, with particular attention to the important process of total transverse acceleration in vessel coordinates. The loci of sway, sway velocity and sway acceleration are shown to follow hyperbolic distributions with respect to elevation in both regular and irregular waves. Expressions are given for the elevations minimizing transverse plane processes in regular and irregular waves. The effect of hull form, transverse stability and natural roll period on transverse plane motions are examined in an attempt to resolve the dichotomy of views between those who favor ships with low GMT and long natural roll periods and those who favor high GMT with short natural roll periods
