Wonder how many of those black-shirted thugs would volunteer to go out in a horrific storm in order to save someone in trouble. It takes a lot to capsize a lifeboat, and the RNLI deserves our support and thanks. Their bravery was tested in February 2020 during Storm Ciara, and we don't forget.
Two pictures of the Hastings Lifeboat battling a raging sea during Storm Ciara in February 2020. The first picture shows it rearing out above a wind whipped wave, and the second picture shows the lifeboat on its side in a position that you never want to be in.

Five lifeboats facing the beach on the day when our old Mersey Class lifeboat was replaced with a new Shannon Class lifeboat. The RNLI is one of the greatest institutions this country has, and we are so proud of them.
