Fergal, they just go astern and sail in between the bouys. For these expensive yachts ,their owners employ first class skippers and crew.

Silly question time.. how do the yachts get behind the mooring buoys? Maneuver between or around?

@ rd77 and Phil, yes Phil ,just as you said IT is the EOS the name can be seen just like you said ,I just relied on the marinetraffic info. This is not the first time that marinetraffic put erratic info and misled me and others.Sometimes I have seen different vessels on the marinetraffic that are actually moored in the harbour.
Sorry that I may have misled others by this info and thanks to all who have pointed it out.

Hi Steve, no actually I did not, I just wrote down what the marinetraffic was quoting on her moored at the Marina.

When you enlarge the photo to full size, the nameboard below the bridge deck reads "Eos"

IMO 9377456. According to her AIS signal, she is still named EOS.

Hi Emmanuel,
Did you actually see the name as being E1? She was formerly Eos
