This study aims at examining the historicity of petik laut (a maritime tradition) as part of the local genius of cultural hybridization between Islam and ancestral beliefs. Sense of belonging possessed by the Puger community has become the start of the foundation of a multicultural society in the community. This multicultural spirit eventually strengthens nationalism in the country. The methods used in this historical study are respectively (1) heuristics, namely the collection of data through observations, library research, in depth interviews with related parties, (2) criticism, namely internal criticism through the testimony of fishermen and the juru kunci (ritual leader) of the Larung Sesaji tradition in Puger, and external criticism through lecturers and cultural experts, (3) interpretation, explanation of verified data, (4) historiography, namely writing history. The results of the study revealed that a series of maritime ritual is a blend of Islam and animistic traditions. The purpose and objective of the various maritime rituals are usually the same, that is, to ask Gods blessings so that the fishermen will be provided with abundant fish and will be freed from any disaster when fishing. Most of fishing communities believe that the sea is guarded by supernatural beings. In a policentric society, every single maritime ritual is a solidarity making event.
