Following a helicopter accident in August 2019, the power lines crossing the SE end of the Poros channel were damaged.
It is understood that the air height of the power lines is currently just 26m, much less than the charted 46m.
Recent unconfirmed reports suggest that the lines may have been raised slightly, but they are not due to be tightened back to the charted height until late October.
Until then all vessels with air height over 25m are advised to use only the north entrance to the Poros channel.
Please refer to local Notices to Mariners for the latest information.
