Bow windshield
Watching the Solent to see if the sea was as rough as we had been led to expect (it wasn’t) we saw the CMA CGM Montmartre leaving Southampton on her one-month voyage to Port Klang in Malaysia.
She is an extremely large vessel, but was making way on her own, without the assistance of tugs, so presumably was relying on large, effective bow thrusters to make the sharp turn into the main channel.
We noticed her large green bow windshield, or wind deflector. Such devices have been fitted on container ships since 2015. They have proved to improve a ship’s aerodynamic profile, reducing resistance, fuel consumption, and carbon emissions.
At present, bow windshields can only be seen on container ships, but it is expected that environmental considerations will see them becoming more widely employed. They can be retrofitted on existing ships in dry dock.
