Star Ferry is a renowned transportation crossing Victoria Habour between Tsim Sha Tsui on Kowloon side to Wan Chai or Central on Hong Kong Island side. In addition, they provide a service reaching from Tsim Sha Tsui on Kowloon side to Disneyland with a dear price.
New World First Ferry mainly provides ferry service from Central to Oultlying Islands. Other services also provided.
Coral Sea Ferry mainly provide ferry from Sam Ka Tsuen to Tung Lung Island. Honestly, there is not much to explore in Tung Lung Island. However, the boat is designed in a very local style. The ferry pier is designed in very nice local styles so it does not hurt to go and have a look at their Sam Ka Tsuen pier. Unfortunately, their official website is in Chinese version only. Shoot them email (not sure if it still works) or give them a ring on (852) 2368 8885 when you have some questions on mind.
There are heaps kaito along Sai Kung Pier. Don;t worry you cannot find one becuase you do not need to look for one coz they are the ones who are eager to look for you! They are always standing near the pier! Another spot is Wong Shek Pier in which the operators of kaito are not obvious. They usually hang around the boat landing spot. Check out the details at Hong Kong Tourism Board.
Why not save HK $2 from MTR Fare Savers on your MTR ride when you are near these spots.
It is especially helpful when you travel between Kowloon and Hong Kong Island or other long distance trip on MTR. Conditions apply and please check on their official website and dig out more!

Hong Kong Maritime Museum Gift Shop and many others listed in my book.
I do not suggest going to visit these places because it is quite dangerous and you may breach local laws by trespassing. The haunted places are rated as refuge of ghosts among locals by rumours and it is not my opinion. Just want to put up here for those who are interested in knowing local rumours about paranomal activities: Nam Koo Terrace (Wan Chai), Ho Chung 13 Asia TV Studio (Ho Chung), Sai Ying Pun Community Complex, Tat Tak Communal Hall (Ping Shan), Tat Tak School (Pig Shan), Mount Davis Fort, a certain place in Cheung Chau, Bride's Pool, So Lo Pun Village and French Braid Road in Chinese University.
