This study examines the structural, cultural, and systemic variables affecting women's involvement in the African maritime sector and provides evidence-based measures to promote gender equality in the Blue Economy. A qualitative, policy-oriented research design was employed, integrating ethnographic observation with secondary data analysis and using an ethnographic lens to provide critical perspectives on the lived experiences of women in marine situations. Interviews conducted with 20 female professionals provided instructive information about the direct experiences of female professionals in the marine field regarding their perceptions of gender mainstreaming issues based on their lived experiences. The study establishes that gender equality in the maritime industry is essential for the Blue Economy to realise its maximum potential in Africa. The inclusion of women in the economy not only facilitates its expansion but also fosters social justice and environmental protection. To establish a sustainable and inclusive marine sector, it is necessary to implement institutional reforms, mentorship, digital learning, targeted financing, and data-driven workforce planning. The study recommends that to promote gender equality in the marine industry, it is necessary to ensure that women occupy technical leadership and power positions. Legislation, initiatives that support women's leadership, and positive measures that facilitate their advancement to strategic and high-level roles can achieve this. The findings stipulate that promoting gender equality is not only a matter of social fairness but also a matter of economic and environmental need. Recommendations stress the need for data-driven monitoring, targeted investment, and structural changes to make the Blue Economy fair, open, and long-lasting.
