This week - Why children growing up in coastal communities may have no knowledge of their culture and heritage. A month ago a man told us he was using a garden mat to sail around Ireland on a 13-foot boat. He has done it and raised over €20,000 for an organisation providing educational opportunities for Ireland’s blind and partially sighted children and young adults. We’ll also hear about the deaths of 47 people by drowning so far this year, and more maritime news, comment and information.
