  Theoretical and observational studies have suggested that ram-pressure
stripping by the intracluster medium can be enhanced during cluster
interactions, boosting the formation of the "jellyfish" galaxies. In this work,
we study the incidence of galaxies undergoing ram-pressure stripping in 52
clusters of different dynamical states. We use optical data from the
WINGS/OmegaWINGS surveys and archival X-ray data to characterise the dynamical
state of our cluster sample, applying eight different proxies. We then compute
the number of ram-pressure stripping candidates relative to the infalling
population of blue late-type galaxies within a fixed circular aperture in each
cluster. We find no clear correlation between the fractions of ram-pressure
stripping candidates and the different cluster dynamical state proxies
considered. These fractions also show no apparent correlation with cluster
mass. To construct a dynamical state classification closer to a merging
"sequence", we perform a visual classification of the dynamical states of the
clusters, combining information available in optical, X-ray, and radio
wavelengths. We find a mild increase in the RPS fraction in interacting
clusters with respect to all other classes (including post-mergers). This mild
enhancement could hint at a short-lived enhanced ram-pressure stripping in
ongoing cluster mergers. However, our results are not statistically significant
due to the low galaxy numbers. We note this is the first homogeneous attempt to
quantify the effect of cluster dynamical state on ram-pressure stripping using
a large cluster sample, but even larger (especially wider) multi-wavelength
surveys are needed to confirm the results.
