About the Captain

Paul Tsai

Engineer. Sailor. Finance professional.

Paul Tsai is a dual citizen of the United States and Taiwan with an extensive career in finance and international markets. A UCLA-trained Mechanical Engineer and Carnegie Mellon MBA, Paul Tsai applies a rigorous, systems-based approach to the complexities of maritime logistics.

His engagement with Japan began at age 10, sparking a lifelong connection that included time as an exchange student at Tokyo University's School of Engineering. Now a Permanent Resident of Japan with over 40 years of deep cultural and technical experience, Paul Tsai possesses native-level fluency in English, Japanese, and Mandarin Chinese. This unique background allows him to navigate the intricate legal and social nuances of the Japanese harbor system with the precision of an engineer and the insight of a local.

Paul Tsai's sailing journey began in Japan on a Yamaha 30C, eventually exploring the rugged coastlines of the Japanese islands before sharpening his skills in the demanding waters of the Pacific Northwest. In 2019, he purchased Arona — a Hallberg-Rassy 40 — to begin a circumnavigation.

Drawing on his engineering precision, his MBA's analytical framework, and four decades of Japanese immersion, he authored Sailing Japan: Secrets of Japanese Waters, the first comprehensive English-language logistical guide to the region.

When he's not aboard Arona, Paul Tsai writes for Diamond Financial Research and appears on financial media like StockVoice and PIVOT. The dream of a full circumnavigation remains very much alive.
