The ship registration system in the United Republic of Tanzania is a vital component of the nation's maritime infrastructure, playing a key role in ensuring compliance with national and international maritime laws. This research provides A Case Study of The Effectiveness of the Ship Registration System: Examining the Legal Framework and Administrative Procedures of The United Republic of Tanzania. The mixed-methods approach combined qualitative and quantitative data collection. The findings were to assess the impacts of the legal framework governing ship registration in Tanzania. The study observed that, the maritime sector of the United Republic of Tanzania (URT) operates under a complex legal framework that is divided between two distinct legal systems, each with its own governing authority. This duality is primarily reflected in the Merchant Shipping Act of 2003 and the Merchant Transport Act of 2006, which cater to the maritime needs of Tanzania Mainland and Zanzibar, respectively. The Merchant Shipping Act of 2003 is designed to be applicable across the entire URT, encompassing both Tanzania Mainland and Zanzibar. This is explicitly stated in Section 3 (1) of the Act, which asserts that the provisions apply to all Tanzanian ships, irrespective of their geographical location.
