Roll on roll off Fremantle

Our cruise boat followed the Swan River down to Fremantle. Once in
Fremantle we saw some of the many boats tied up. There were a number of
container boats tied up (with Peter explaining to me which ones were similar
in size to the Rena which grounded late last year on the reef near our home
in Mt Maunganui in NZ), and also a roll on, roll off and Navy boats. The
roll on roll off didn't look that large to me, but when you saw the number
of vehicles parked on the wharf which had been unloaded from this ship it
was evident it was huge.
