A note of caution if planning to enter the harbour and use the Algoa Bay Yacht Club Marina.

If during your stay, there is a bulk carrier loading at the terminal almost next to the marina, and the wind moves to the east, your yacht and the whole marina will be covered in black dust. I have just reported this (December 2015) to Noonsite, who have verified the information with the club. For us it took 6 hours taking a water hose to the top of our mast, to remove most of the dust from our yacht, including a brand new staysail! :(
