Joanna, arriving home to "Watermark" by sampan.
Sampans are the usual means of getting around for those of us with boats moored offshore within the Typhoon Shelter. They can be called by their mobile phone, if you have the number, or by waving and shouting. Our favorite way, and maybe one we can take credit for starting, is by blowing a whistle. At night, waving a flashlight may also attract one that is passing passing by.
When leaving "Watermark", for a day at the office, or a short trip ashore to the marked, I've learned to always carry my charged mobile phone, a small flashlight, and my sampan whistle. One of them will get me home.
