Seafloor Mapping
Since its establishment, Wreckless Marine has conducted extensive high-resolution seafloor mapping off the Western Cape coast, and contributed data to a number of institutions, including GEBCO’s (General Bathymetric Chart of the Oceans) Seabed 2030 project, the Council for Geoscience (CGS) coastal mapping programme, the South African Heritage Resource Agency (SAHRA), the South African Navy Hydrographic Office (SANHO), and the South African National Biodiversity Institute (SANBI). The company offers a complete seafloor mapping and survey service.
Wreckless II
The Wreckless Marine flagship, Wreckless II is a 13m Bobkat catamaran, built in Cape Town by Two Oceans Marine, and powered by two inboard Yanmar 440 HP diesel engines. It is a fully equipped survey vessel fitted with best in class instrumentation and an R2Sonic 2026 Multibeam Echosounder. It has 6 berths, a top speed of 26 knots, a range of 800 nautical miles and 5 day’s endurance.
R2Sonic 2026 Multibeam Echosounder
The R2Sonic 2026 Multibeam Echosounder is state-of-the-art, providing detailed bathymetric data. This is used for seabed and habitat mapping and for shipwreck surveys. The R2Sonic 2026 also has high-resolution side scan capabilities, which is extremely useful for characterising the composition of the seafloor and identifying marine habitats.
JW Fishers Proton 5 Magnetometer
Marine magnetometers measure the magnetic fields in the environment. The Earth’s magnetic field can be influenced by geological features such as dolerite dykes, faults and anthropogenic objects, such as shipwrecks. The magnetometer is used for geological surveys and for searching for shipwrecks and other items, particularly if these are covered by sediment.
