 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 questio 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.
