The museum holds a range of cableship models, both large and small. Many models were made by the ship yard prior to the building of the full sized cableship. Cableships were used to lay undersea cables and to repair cables when they became faulty. The largest cableship was the ‘Great Eastern’ designed by Isambard Kingdom Brunel in 1858. The collection contains marine equipment used on cableships, including sextants, compasses, and lanterns. There are jointing tool boxes containing the equipment for joining two telegraph cables together, full size grapnels used to retrieve cables from the seabed, and uniforms worn by crew members.
