Purple dye marks a rip current

The rip current is the bogeyman of the sea. The confusion engendered by its behaviour and what to do if you get caught has imbued this beast with a reputation such that swimmers fear its very name. This is partly justified; in both Australia and the USA around 100 people a year drown in rip-related incidents, while between 2006-2011 in the UK, RNLI lifeguards rescued 12,607 people from rips, around 11% of whom were swimmers. The biggest problem however is that people don’t understand rips or what to do when they’re in one. This book by coastal geomorphologist Dr Rob Brander (named ‘Dr Rip’ by Lifeguards in New South Wales for his habit of pouring purple dye into rip currents) is therefore an essential addition to the sea-swimmer’s library.

Dr Rip begins with a fascinating discussion of types of sand and the ways in which different sentiments collect in certain places and form different types of beach. This is important, because the type of beach largely dictates the type and size of waves, which in turn affects the formation of currents such as long-shore drift and rips, and whether these are fixed rips or unpredictable flash rips.

There are several categories of wave which Dr Rip describes in detail, along with specific dangers associated with each. From this section I now know for certain that the wave which wiped me out behind Burgh Island last year in twelve-foot swell and scared the bejesus out of me was a freak reflected wave combined with an incoming one, because there’s a description of how such waves form and a picture of a similar one in the book. You will also learn not to try body-surfing a plunging wave or a surging wave, and what to do when a big wave decides to break on top of you – a frequent occurrence for we year-round sea-swimmers and dippers.

There’s a chapter on currents with an in-depth analysis of rips. A rip current (it is a current, not a tide) is a ‘river’ flowing from the shore through an area of breaking waves. It’s a key way in which water from breaking waves returns to the sea. A rip won’t drag you under, it’s dangerous for a couple of reasons: firstly, they appear to be areas of calm in white water, and therefore attract swimmers; and because people who are not competent swimmers or who are not educated about rips get caught and are pulled out of their depth, or try to swim against them because they don’t know how to get out. So the first important point is how to spot a rip; there are plenty of handy hints and excellent photographs to help you develop this essential skill, along with advice about where, and where not, to swim.

One of the refreshing aspects of the book is that there are no absolute rules. Dr Rip simply discusses the various options which are of course different depending on your ability and fitness. So you learn a couple of ways of swimming out of a rip, or how to attract the attention of a lifeguard. Some rips will run you a mere 50-100m off shore and return you to the shallows after a couple of minutes, while others are monsters; one in New Zealand, for example, took Dr Rip a good 1km off shore, and while they are normally narrow, they may be up to 50m wide and travel at the sprint speed of an Olympic freestyler.

There’s a chapter on tides which, Dr Rip explains, are a type of wave. We also learn that tsunamis are surging waves which accounts for their huge destructive power; there’s a fascinating discussion on the reason the 2004 tsunami caused barely any damage in the Maldives, despite running straight over the islands which are almost entirely at sea level. Other considerations, such as weather, erosion, and the problems associated with thoughtless and poorly-informed shore development are also included.

There’s so much information in this book, all illustrated with wonderful photographs from around the world, that it’s probably necessary to read it two or three times. I grew up (or rather survived my childhood) on the Atlantic coast of Devon, and there is plenty here that I didn’t know. Dr Rip has a life-long fascination with the subject (he collected several hundred jars of sand over his youth which were confiscated by customs when he moved to Australia) and is an expert in the science of beaches and how they work. He writes in an accessible style while also managing to explain some fairly complex processes in an easy and entertaining way. There are some lovely touches of humour. You will even learn how to survive a shark attack (swimming with a friend immediately reduces your chance of attack by 50%!) There’s also information on fossicking on a beach, rock-pooling, and where and how to build a decent sandcastle.

My only criticism is in the sometimes confusing format where summary sections are placed in mid-paragraph rather than at the ends of the relevant chapters, but it’s such a great book it’s well worth overlooking this minor annoyance rather as you would a sand fly bite. By the way, before you warm yourself up on your nippy winter sea swim, did you know that sharks are attracted by the smell of wee?

Dr Rip’s Essential Beach Book comes very highly recommended for anyone who swims in the sea.
