Onboard stability guidance systems have been proposed by many authors as a possible solution. These guidance systems have been evolving from colour-coded posters to computer-based systems. However, their real-time operation without crew interaction is not solved yet. This work presents the validation of a methodology proposed by the authors in previous works for estimating the natural roll frequency of the vessel in real-time and thus the metacentric height. The performance of this method, based on the analysis of the roll motion, is tested during a fishing campaign of a mid-sized trawler, showing very promising results.engAttribution-NonCommercial-NoDerivatives 4.0 International (CC BY-NC-ND 4.0)https://creativecommons.org/licenses/by-nc-nd/4.0/Fishing vesselsIntact stabilityStability monitoringGuidance systemsSea trialsjournal articleopen access10.1016/j.oceaneng.2022.111841
