Route Context

This measurement assumes departure from Avonmouth (Bristol's deep-water port) to Gibraltar Harbour, following the great-circle track across the Celtic Sea, past the Bay of Biscay, through the Strait of Gibraltar. Actual sailed distance varies by:

• Vessel draft and routing: Larger ships may stay farther offshore in the Bay of Biscay
• Weather routing: Winter storms often push courses south, adding mileage
• Traffic separation schemes: Mandatory lanes off Ushant, Finisterre, and in the Strait
• Port approaches: Pilotage and channel navigation add 5–15 NM each end

Typical Passage Times

• Commercial vessel (12–15 knots): 3.5–4.5 days
• Fast ferry / naval vessel (25–30 knots): 1.8–2.2 days
• Sailing yacht (5–7 knots avg): 8–12 days (weather-dependent)

Gibraltar's strategic position at the Mediterranean gateway makes this a historic and heavily trafficked route—from Phoenician traders to Royal Navy squadrons to modern container ships.
