CTruk Survey


Maplin is a first-in-class hydrographic survey vessel for The Port of London Authority. Its resin-infused composite construction keeps it light, robust and efficient - and in accordance with client demands, its low-profile wheelhouse and foldable mast help it negotiate the tight bridges of the Thames with ease. It also houses a retractable, hull-mounted multi-beam sonar, plus a moonpool, an A-frame and a deck crane. Combined with its refined interior and extensive options list, this generates true multi-function ability as well as advanced passenger comfort.
