What travellers say: Seatran Discovery vs Raja Ferry

Both operators earn solid ratings above 4.2 from thousands of reviews, with travellers highlighting reliable service alongside recurring practical frustrations on Gulf of Thailand routes.

Seatran Discovery

Reviewers praise Seatran Discovery's high-speed ferries for smooth, well-organized journeys, helpful staff, convenient combined transfers and good value, though delays of 30-90 minutes, unpredictable AC, ageing vessels and chaotic luggage handling draw frequent complaints.

Raja Ferry

Travellers rate Raja Ferry highly for comfortable buses, free meals, friendly staff and stable large ferries that reduce seasickness, but note the ferry legs themselves score lower due to old, dirty vessels, lack of baggage assistance and occasional long waits or transfer confusion.

Seatran edges out with a slightly higher average and stronger organization feedback while Raja excels on bus comfort and value; book either confidently via ThailandBoatTickets.com where our 24/7 Virtual Ticket Assistant (VTA) on WhatsApp, Instagram DM, Telegram or Facebook can assist with your journey.
