#Rio2016 - Rio's water 'will be ready' for sailors when the Olympic Games begin in August, according to China's Xinhua News Agency.

Speaking at an event to mark the lighting of the Olympic torch in Athens on Thursday (21 April), International Olympic Committee president (IOC) Thomas Bach told the media: "We are very confident that the competition area for the athletes will offer safe and fair conditions.

"The city, the state and the organising committee are undertaking many efforts and what we see now is that 60% of the surface is clean," he added. "Without the Games it would be zero."

However, Bach made no reference to concerns over viral contamination of the notoriously polluted Guanabara Bay, nor the risk posed to female sailors by the spread of the Zika virus.

#Rio2016 - Sailors in Rio who ingest just three teaspoons of water from the Olympic courses on Guanabara Bay have a 99% chance of being infected by a virus.

That's according to the latest damning findings from the Associated Press, following from its own investigation earlier this year that found levels of viruses detected at the Olympic sailing venue to be as much as 1.7 million times this allowed on California beaches.

Samples taken more recently now indicate that a high concentration of viruses is detectable even more than a kilometre offshore away from the pollution sources that have plagued Rio's waters for decades.

Despite assurances by the ISAF – which previously floated the idea of moving the sailing venue out of Rio to cleaner waters – that steps were being taken "to ensure the health and safety of all athletes", there was still an illness rate of 7% among sailors competing at an Olympic test event in August.

That figure included 49er bronze medallist Erik Heil, who was treated for severe inflammations in his legs and a hip.

The cause of his illness turned out to be the superbug MRSA, and Heil has since proposed wearing plastic overalls while sailing out from the shore to limit his exposure to that an other bacterial infections.

But experts in waterborne viruses have told the AP that such efforts are futile when Rio's Olympic waterways "are as rife with pathogens far offshore as they are nearer land".

The AP has much more on the story HERE, coming in the same week as the ISAF's chief executive Peter Sowrey resigned after only six months in the job – the latest in a spate of high-profile departures from sailing's world governing body.

#Rio2016 - The blame for Rio's pollution woes should fall squarely on local political leaders and not on sporting bodies, according to the head of Britain's sailing team.

As Scuttlebut Sailing News reports, Stephen Park says the press should turn its attention to those responsible for the notorious pollution problems in Guanabara Bay – the sailing and windsurfing venue for the 2016 Olympic Games – rather than place the burden on sailing's country leaders to withdraw from the venue.

Park's comments come in the wake of news that another sailor was hospitalised after the recent Aquece test event with a bacterial infection believed contracted in Rio's waters.

According to Sail-World, 49er bronze medallist Erik Heil was treated for severe inflammations in his legs and one hip which he says began on his journey home from Rio.

And the sailor has explicity blamed his illness on the waters of Marina da Glória, where wastewater from the city's hospitals flows openly into the bay, and has had his case taken ip by the German Olympic Sports Confederation, as the Guardian reports.

Heil's post-Rio illness follows that of Kiwi 470 sailor Jo Aleh, who missed three races at Aquece over a bug alleged to be connected with water contamination, and South Korean windsurfer Wonwoo Cho, whose hospitalisation came just days after the ISAF's latest threat to move Olympic sailing events to a new course in the Atlantic.

As previously reported on Afloat.ie, a recent investigation into water quality at the current Olympic sailing venue found that athletes are "almost certain to come into contact with disease-causing viruses".

About Electric outboard engines

The direct-drive component in electric outboard engines means that the electric motors are incredibly efficient compared to conventional marine combustion motors, operating with considerably higher torque whilst using less power.

Without any need for gears, cooling systems and moving parts the motors are maintenance free, highly efficient and economic to run.

As a result, electric boat engines are becoming more popular on Irish waters as the world transitions from fossil fuels to green energy.

To date, popular electric engine sizes have been trolling engines typically used by fishermen on lakes.

These marine engines are available in models that can be used in fresh water and sea water, for your boat or kayak.

Electric motors are Ideal for fishermen because they are quiet and create little in the way of disturbance 

Popular electric trolling models range from 30lb thrust to 55lb thrust in a range of shaft lengths.

But use is becoming broader now in 2021 and electric outboard engines are being used on small runabouts and RIBS where electric outboard engine sizes are getting bigger.

Outboard electric engines are economical and environmentally friendly. Battery technology is also improving at a rapid rate meaning they are becoming smaller and lighter and run for longer.

Built in hydro-generation provides alternative recharging options whilst under sail are also options meaning the electric outboard now has a home on the stern on small yachts and dayboats too.

As far back as 2014, Torqeedo owner Jack O'Keefe from Cork Harbour told Afloat readers of his sailing adventures in a Drascombe Coaster dinghy and how after swapping from a petrol version the rewards from his new electric outboard engine are less noise, no smells, more stowage, better sailing performance and a motor that can be started by a small child. But it's still not silent, there's a whine he says here 

Popular brands in Ireland are Torqeedo, ePropulsion, Pulsar and Minn Kota but there are more arriving all the time as the technology advances
