Wynne & Joanna: All at Sea S01E06 - New Horizons

The final leg of their journey to St Davids sees the pair set off from the Cleddau River estuary before heading into open seas.

Their first stop; joining the RNLI St David's lifeboat team for an action-packed training exercise where they take their turn at the helm of the boat. Then there's a quick call in at St Davids, Britain's smallest city, before heading back to their boat.

Their final stopping off point is Porthselau Beach where Wynne and Joanna take a dip in the sea, joining others out for their daily swim before they turn the boat around and start heading for home.
