Inter-Island Boat Crossings: The Falowa

The small passenger vessels operating between Batan, Sabtang, and Itbayat are called falowa (also spelled faluwa).

Why Falowas Have No Outriggers

Unlike standard Philippine bangka boats with bamboo outriggers (katig), the falowa is built with a rounded, heavy wooden hull and no outriggers. This traditional design prevents the vessel from snapping outrigger arms when rolling in the deep, turbulent swells of the Sabtang Channel.

Crossing Details: Batan to Sabtang

• Port of Origin: Radiwan Port, Ivana (South Batan Island).
• Destination: Sabtang Port, Sabtang Island.
• Transit Duration: 30 minutes.
• Departure Schedule: Boats depart Ivana between 6:00 AM and 7:00 AM. Return boats leave Sabtang between 1:00 PM and 2:00 PM.
• Fare: ₱100 to ₱200 per passenger per way.

Philippine Coast Guard Regulations & Grounded Boats Policy

Safety on all sea routes in Batanes is governed strictly by the Philippine Coast Guard (PCG).

1. Daily Clearance: Every morning, the PCG inspects wave heights and wind speeds in the Sabtang Channel before authorizing falowa departures.
2. Grounded Crossing Protocol: If a sea ban is declared, boat trips are suspended immediately. Qualified tour operators (such as J-Line Paradise Tours) automatically adjust your itinerary: moving land-based South Batan or North Batan tours to the grounded day and rescheduling Sabtang when Coast Guard clearance reopens.
3. Motion Sickness Advisory: The Sabtang Channel is known for rolling swells even on clear days. Passengers prone to seasickness should take motion sickness medication 30 minutes prior to boarding at Radiwan Port.
