They are ongoing and will be updated as we move into phase 2.
The Murray river will involve the second construction of a vessel and the first journey. The construction will happen in Port Adelaide, transport to the launching place will be from our support team.
One question that remains very open is our expected speed along the river. Which is closely dependent upon the water speed. On one extreme we have:
“With the exception of Weir 6, Murtho, the weir pool of each storage extends to the storage upstream. Therefore, the River Murray between Blanchetown and Wentworth is more like a series of lakes than a lowland river, particularly when river flows are low.” from http://www.murrayriver.com.au/about-the-murray/locks-weirs-dams-barrages/
From the flow rate measurements, estimating the river width at around 150m and the depth 4m (probably too deep) we get a speed around 500 m / hour, i.e. half a kmh. because we overestimate the cross section of the river, this number is probably too low.
From people travelling on various European rivers, upstream as well as downstream, we have travel distances around 40 km per day. This seems too high.
Vessel construction and testing January 23-28, Journey 1-21 February, Parade 24 February.
Launching around Ned's point or Lock 9.
Travel is expected to be between 20 and 40 kilometers per day, based upon experiences of 2 similar projects. Water currents will be important. The can be found [[here]http://riversmart.net.au/Flowtracker.htm], and it seems that if we take the river to be 150m wide and 4 meters deep, the flow at the SA border is around 0.5 kmh, compared to 4-6 on the Danube. Maps of the river are available here: http://www.rmboa.org.au/maps.html
The vessel will be built from scavenged, recycled or otherwise low impact parts.
Sail will be a junk rig, oars will be used and possibly a Yuloh. A tentative plan for pedal power exists - details at the beginning of January.
Some things to bear in mind for the Fringe parade finale on 24 Feb.
Things we will need: please edit as things become available.
