Here are a few seaonal photos. This vessel is the "Nella Dan". It supported Australian expeditions to the Antarctic between 1962 and 1987. It played host to numerous helicopters including those from Helicopter Utilities (Bell 47 and FH1100), Jayrow Helicopters (Hughes 500), Vowell Air Services (Hughes 500 and Bell 206) and (I believe) Chopperline (Hughes 500D). It also transported other forms of transport including the DHC Beaver, Pilatus Porter, amphibious landing craft, the Sno-Trac tracked vehicle and the VW Beetle! The helicopter landing pad was approximately 100 square metres in size and must have felt positively airport-like when compared to some of the compact helidecks on show in the "Superyachts" thread.
It looks like one of Vowell's blue and red 500s is resting on the stern in the photo above.
The aforementioned A.N.A.R.E. VW Beetle.
Finally, here is a beautiful photo of Jayrow's colourful Hughes 500 VH-SFS cruising along in front of an impressive background.
