Our short Christmas break down on the muddy banks of the Breede River was less about waterskiing and more about sleeping, reading and eating. One reason for this – although no-one’s actually admitting it for fear of being called chicken – is that the large Zambezi shark named Nyaminyami which last year was hooked and tagged 30km upstream of the sea, has not been seen for some time.

This makes waterskiers nervous. Still, it’s hard to see how a Zambezi shark would mistake a skier for a seal, but then the Breede’s waters are murky and there’s no accounting for what sharks might or might not do.

Up on the South Coast, a poster (see above) helpfully explains why sharks attack surfers. Because they look like turtles. Or seals. So, that’s alright then.
