Pak Nam, or the ‘Mouth of the Water’, is the area from the Samut Prakan to the sea. The channel starts six miles south of the mouth of the river leading up to Pak Nam, and is clearly marked by 40 green and red buoys. The channel is 7 metres deep and is commonly used by ocean-going cargo ships as well as by smaller local boats and barges. Currents are significant, especially the south-setting flow during ebbing tides.
