Book Your JourneyOur Story
Founded in 2005, Boonsiri Sealine Ferry began with a simple mission: to provide safe, reliable, and comfortable transportation between Thailand's mainland and the beautiful islands of the Gulf of Thailand.
What started with a single vessel connecting Chumphon to Koh Tao has grown into a comprehensive network of routes serving all major islands in the region, including Koh Samui, Koh Phangan, and connections to Surat Thani, Hua Hin, and Bangkok.
Today, we operate a modern fleet of high-speed catamarans and traditional ferries, carrying over 500,000 passengers annually. Our commitment to safety, reliability, and customer satisfaction has made us the preferred choice for both tourists and locals traveling between Thailand's mainland and islands.
