Liquid fuels, aggregates, cement, construction materials and scrap metal make up the cargo mix at St Sampson's, Guernsey's working freight harbour. Around 350 cargo vessels call each year; containers and international liner services, however, are not part of its remit. Coastal tankers feeding the St Sampson Terminal discharge six fuel grades — including ULSD, kerosene, Jet A-1 and HVO — through pipelines into shoreside storage tanks. Because the basin dries at low water, arriving ships must be certified NAABSA (Not Always Afloat But Safely Aground) and worked within tidal windows. Hinterland distribution relies entirely on the island's road network, with no rail connection. General cargo and passenger freight move through neighbouring St Peter Port, while containers typically reach Guernsey as lift-on/lift-off feeders via UK ports such as Portsmouth or Poole. Operators should plan around tidal windows and the limited quay length well in advance.
