Guest Posted July 14, 2014 Share Posted July 14, 2014 How on earth would swim in Westhaven unless they had a specific need to? In my case that specific need is I was generally the smallest or the slowest so I get to scrub the bums....... in which the head is under a lot. Being electrocuted never crossed my mind but then the growth in shore power connections is reasonably new. Swimming in westhaven is not a regular activity granted but diving is. but hey some people may want to swim there?... after all the TBT levels are way down and there is less chance of growing an extra Testicle. And.... the greens want us all swimming in every river and westhaven will be next. yip... clear them boats out Normans in town!!! you can see it know!.... Pure 110% NZ and Nobody here/bankrupt!

Scubash 0 Posted August 2, 2014 Share Posted August 2, 2014 Ok if anyone is thinking of a clean this week for the SANZZ series on saturday 9th. Please ask now rather than last minute so we can organise ourselves. cheers Link to post Share on other sites

AJ Oliver 154 Posted August 7, 2014 Share Posted August 7, 2014 The Sweetwater Seas (sorta fresh water), where we are, are far more dangerous to swimmers where there is stray current than is salt water. http://www.oceannavigator.com/October-2 ... ck-danger/ Awesome thread drift !!

MarkMT 68 Posted August 8, 2014 Share Posted August 8, 2014 I ran across this this morning from the Racine Yacht Club in Wisconsin where I'll be racing the next couple of weekends... http://www.racineyachtclub.org/reefpoint/2014/rp201407.pdf Cautionary notes: It is not safe to swim in our dock system. It is not just our system; it is ANY electrified dock system or a pier serving those with on-board generator sets. I have been a long time marina swimmer and see this with much disappointment. Here’s the rub: Only very tiny amounts of current are needed to induce Electro Shock Drowning (ESD). Through faulty wiring in the dock infrastructure or bad bonding/grounding on individual boats, current leakage of as little as 15 mA (milliamps) can lead to paralysis and drowning. Now the facts. We made out first full pass on the slip system with equipment to test voltage and current flow on individual boats and “stray-current’ in the water surrounding our finger piers. Our results were surprisingly good. With the lead of Bob and Carol Kunath, several hours of testing showed the vast majority of the slip system in the ~2-3 mA region. Is this safe enough to swim? In a word, no. On the related topic of the beach and the children who wade in the water: We can’t say that is safe but if there was current leakage from the slips in that proximity, the intensity drops rapidly as distance increases (I=1/d^2). Our measurements in the beach water were -0-mV and -0- mA. There are things that the average person can do to minimize the risks to other boaters and other boats. Buy a polarity checker and use it. Make a visual check of the condition of all plugs and receptacles. Burned or charred prongs are a sure sign of trouble and they should not be used. Use ONLY grounded cords and make sure that cords stay out of the water. If you see a cord in the water, rectify that condition or contact somebody who can cut the power, and safely secure the shore power cord. There’s a lot more to this issue and we have to develop some guide lines and procedures to insure we have a safe environment for all of our members and guests Link to post Share on other sites
