S. A. Agulhas II is a South
African icebreaking polar

by STX Finland this year. A JIP

was arranged in the ice trials
giving new and valuable data
to AARC.
The multi-purpose vessel S.A. Agulhas
II, ordered by the South African
Department of Environmental Affairs in
order to replace the 35-year old S.A.
Agulhas in demanding tasks in the
Antarctic, has safely arrived at her home
port, Cape Town and is now preparing for
the first voyage to Antarctica. She was
constructed in Rauma, Finland.
Research onboard
The ice-strengthened ship has been
designed from the beginning to carry out
both scientific research and supplies to
research stations in the Antarctic.
She can spend several months out at
sea and acts as a mobile laboratory.
Scientists can conduct a variety of
marine research onboard the ship, which
is also classified for carrying passengers.
Furthermore, the vessel keeps record of
weather data for meteorological
institutions around the world. The vessel
has a shelter and landing area for two
helicopters and it features eight
