I got curious and looked up the Hei Ling Chau spaces- seems no water or electric? Didn't say (couldn't find it) how many spaces but applications are due September 30th. Very close by (about 20 minutes by slow ferry) so hopefully could move even a house boat there. At least they could have a place to put it- Hei Ling Chau is a restricted area due to the prison but there is ferry service between HLC and Peng Chau- some from Central, just stay on the ferry and it continues to HLC. Or get off at PC and take kai to to DB for school?
Not a really viable solution I guess without electric and water. Maybe the government would provide these things? It's there on HLC, seems possible to route it to the typhoon shelter.
We have public bathrooms with showers on PC that I guess are for the fisherman- there seem to be people that live on boats moored around PC. Small fishing boats- some near my block of flats- like I see laundry hanging on them and such.
