<![CDATA[Watchkeeping duties plays an important role in ensuring navigational safety, particularly when a vessel encounters adverse weather conditions that can reduce visibility and affect ship stability. However, based on observations conducted on board MV. OPS ASTRID, the implementation of sea watchkeeping still faces several challenges, including an unbalanced watch schedule due to a limited number of officers and less optimal coordination between the bridge and the deck during extreme weather conditions. Therefore, this study aims to analyze the implementation of sea watchkeeping and identify the problems that arise when the vessel sails under adverse weather conditions. This research employed a descriptive qualitative method, with data collected through direct observation during the voyage, interviews with the Chief Officer, Second Officer, Bosun, and Able Seamen (AB), as well as a literature study referring to the provisions of STCW 2010 and COLREG 1972. The results indicate that sea watchkeeping on board MV. OPS ASTRID has generally been carried out in accordance with navigational safety procedures; however, its effectiveness is influenced by an unbalanced watch schedule and communication constraints between the bridge and the deck caused by adverse weather. These conditions may reduce the effectiveness of navigational supervision, indicating the need for adjustments to the watch schedule, improved communication between watchkeeping positions, and additional supervision to maintain navigational safety.]]>
