This research was motivated by the policy of putting marine tourism as a superior sector to be developed in West Halmahera Regency. This prompted the Tourism Department to declare the year of 2013 as a tourism year in West Halmahera, but until 2018 it has not reached the target. The purpose of this research was to analyze the implementation of maritime tourism development and its impact. This research was qualitative research. Data collection was done by in-depth interviews, documentation, and observation. Informants were obtained by purposive sampling. Data were analyzed by triangulation technique with data reduction stage, presentation, verification and conclusion. The analysis showed that the implementation of marine tourism development policy had not been maximized. Tourism infrastructure such as lodging facilities in tourist attractions are still lacking, access roads are damaged, and the transportation facilities are still minimal. On the other hand, the promotion aspect can be said to be successfully seen from the benefit of the increasing income earned by business actors and the society during Jailolo Bay Festival implementation. Based on these findings, the recommendations that can be given are: (1). Conducting an assessment of supporting facilities that are more focused on marine tourism activities by increasing the budget allocation for infrastructure development, (2). Management of tourism development policy management which must be in the context of Halmahera. (3). Increasing the training and participation of society and business actors in developing marine tourism.
