As the summer approaches many families will be spending time near the water. We are lucky to be surrounded by beautiful beaches but also by the dedicated men and women of the RNLI who risk their lives each day saving the lives of others. It is estimated that the RNLI save at least 23 lives every day. You can help supporting their invaluable work by donating here.
