From the breakwater in Greymouth you can view the harbour entrance over the shifting sands of the bar. On YouTube you can see some hairy footage of fishing boats making their way in against a strong ebb tide. We went to take a look, and found flat calm with a couple of porpoises playing around. We also found a fab Dutch guy making stroopwafels in an old lifeboat. He wants to sail round the world and we had a great chat.
