Our Coast: County Down, Northern Ireland

Adrian Chiles and Mehreen Baig explore the Co Down coastline between Belfast and Strangford Lough, along the Ards Peninsula. In Belfast, Adrian road-tests the largest hydraulic crane in the world and helps park a 100-metre-long Dutch cargo ship. Mehreen goes kayaking on Strangford Lough to see how the currents of the UK's largest sea inlet is placing the area at the forefront of renewable energy research. Plus, Helen Skelton tests the waters of the North Channel, one of the most dangerous swims in the world, and local comedian Shane Todd visits a long-established bespoke racing-car factory
