When I said northern end, actually meant the southern end of the harbour.
The southern end (nearest Cape Town) is the shallow end wheres the Northern end is the commercial harbour.
Also, you mention sharks. Everybody mentions sharks in their second sentence about windsurfing in SA.
Dunno why. No wind surfer has ever been killed by a shark there.
I blame the media in promoting sharks as canny man-eating predators.
In truth, the Cape Town sharks have too many seals to eat.
You won't see one at Blouberg or at Langebaan.
