Merchant Navy Day
We’re calling on communities across the UK to celebrate their Merchant Navy, by flying the Red Ensign on Merchant Navy Day, 3 September.
Our charity’s ‘Fly the Red Ensign’ campaign, which started in 2015 to address the lack of awareness about the contributions of merchant seafarers, has now become a time to celebrate and champion these everyday heroes.
Since its inception, the campaign has grown into a significant national event. The Red Ensign, known affectionately as the 'Red Duster,' is flown at historic properties, political establishments, parish and town council offices, and village greens across the UK. This powerful symbol serves to highlight the indispensable role of merchant seafarers - past, present, and future.
Merchant Navy seafarers’ bravery kept supply lines open during global conflicts including the world wars, as well as crises such as the Covid-19 pandemic. Today, merchant seafarers are indispensable, handling 95% of the UK’s traded goods, yet continue to face stern challenges such as the ongoing situation in the Strait of Hormuz.

“
‘It’s that time of year when I seek your support in marking Merchant Navy Day on Thursday 3rd September by flying the Red Ensign. This year more than ever, our dependence on our nation's Merchant Navy has been highlighted by the events in the Arabian Gulf and especially the Strait of Hormuz. Whether flying the flag or spreading the word about their tireless work transporting our island nation’s trade, this is an excellent opportunity to show our seafarers and their families how much we all value them. On behalf of The Seafarers’ Charity, thank you in advance for your support.’
