Another of  Jerseys early ports, St Aubin became the main harbour for commercial trade to Jersey during the early 17th - early 19th centuries offering shelter to the growing number of merchant vessels collecting and delivering cargo and goods to the island.

Guarded by the fortifications of the St Aubins Fort, just east of the harbour mouth, St Aubins harbour has been extended several times over the centuries, to accommodate the growing number of merchant vessels, until the early 19th century.

With St Helier harbour becoming the main port for the island by the mid 19th century St Aubins has since transferred it's services to the more relaxed pace of pleasure crafts and is now home to some 250 boats, both inside out outside the harbour.

Visiting crafts are directed toward the visiting berths along the west arm of the harbour piers, where water and electricity is available. Visiting craft are also advised that St Aubins is a drying harbour and should therefore ensure their craft can take the ground during low water periods
