The first shot of the boat looks to have been taken along the coastline very close to the modern day roundabout where Tai Mong Tsai Road meets Sai Sha Road.
Also a few shots looking back towards the West Country Park coastline from the eastern side of Sharp Island.
And a couple shots in the same place but this time looking back south towards High Junk peak in the far distance (lower photo far right).
And some final shots of the speedboat as it approaches Sai Kung town to evade the chasing PLA Navy boat. The lower shot is of course looking back out towards Sharp Island.
