RV Investigator provides approximately 35 berths for scientific staff, up to 11-12 berths for Marine National Facility technical staff and 20 berths for the vessel crew.
Cabins include en-suite washroom facilities with a toilet, shower, hand basin and toiletries cabinet. Cabins have a desk, a lounge chair and storage space for clothes and personal items.
Each cabin has power sockets, Ethernet network sockets, an AM/FM antenna socket and a satellite TV socket. The AM/FM antenna and satellite TV antenna are set up to receive Australian content offshore to approximately 200 nautical miles, although access to AM and shortwave radio may extend further.
The Chief Scientist and Voyage Manager have single cabins with adjoining offices. The vessel crew also have single cabins, as they live on board the vessel for extended periods. For the remaining participants, twin cabins are typically allocated based on alternating watches so there is usually only one person in the cabin at a time.
