    Dropping onto the Baychattan is like stepping back in time, if time travel involved a cold plunge into the Atlantic. This isn’t a shallow reef bimble, so bring your twinset and make sure your drysuit is sealed tight. We love how intact she is for a ship that met her end over a century ago. You’ll trace her massive 110-meter length, starting with the bow, often upright and proud, before working your way along the deck. The bridge area is our favourite, where the telegraphs and helm often remain, encrusted with dead man’s fingers and hydroids. Visibility can be a real mixed bag; if you catch it on a good day, the light filters down, illuminating schools of pollock that dart between the superstructure. Even when it's murky, the sheer scale of the ship is impressive, looming out of the gloom. This site truly suits experienced wreck divers who appreciate history and don't mind a proper expedition.

    The SS Baychattan began her life in 1906 as the Kilchattan, built in the famous shipyards of Glasgow. She was later acquired by The Bay Steamship Co. Ltd., joining their fleet of cargo vessels. During World War I, she was engaged in long-haul transport, bringing essential goods from across the British Empire to the home islands. In the autumn of 1917, she was on the final leg of a long voyage from Karachi, carrying a general cargo destined for London.

    On October 11th, 1917, as she navigated the English Channel south of the Eddystone Lighthouse, she was spotted by the German submarine UB-40. Without warning, a torpedo struck the vessel, sealing her fate. The Baychattan sank beneath the waves, another victim of Germany's unrestricted submarine warfare campaign which aimed to starve Britain into submission.

    Today, the Baychattan is a deep technical dive, lying upright on the seabed at 53 meters. Her significant depth has helped preserve her, and while the wooden superstructure has long since rotted away, her hull remains impressively intact. The most prominent features for divers are the massive triple-expansion engine and two large boilers, which stand proud amidships. The wreck is often subject to strong currents, but this can result in excellent visibility, offering a spectacular view of this historic vessel and the deep-water marine life that now calls her home.
