There's no need to wear a PFD any more when paddling on the Yarra river.
We used to do night paddles on the Yarra all the time.. Through the city.. then watch the fire go off at Crown.. then paddle up and under the Bolte bridge.. and on through the docklands.. and back..
All in the black of night.. There's no other water craft and the city lights are enough to see.
