I bet it's the most unique air Bnb experience you can have in Hong Kong. The boat is beautifully and uniquely decorated, and located at an absolutely tranquil area surrounded by sea and mountains. The most special experience is offered by the host and made this trip unforgettable. They prepared great food, we got very fresh and at the season seafood from the nearby fish farm. Activities wise, we flied kite, swim, kayaking, island hoping and treasure hunting (seafood).
Most important they thoughtfully and carefully maintain the boat with special techniques which it doesn't move much and I had a very good night sleep after a whole day of activities.
They know best of the area and suggested what you can do and will company you if you don't mind. I and my daughter had such a great time on this boat and with the hosting family, was a great vacation we really relax and enjoy!
