Alissa and I motored the few miles up the Tagus estuary to the marina at Oeiras.  We proceeded very cautiously in very dense fog.  The air was completely still and it was very eerie at sea.  Had to wait off the marina until we could make out the entrance.  The fog lifted at about 11, and the day has been scorching since.

 

Best marina so far (and the cheapest – by virtue of the ARC discount)!

 

We made a trip into Lisbon to meet Liz who had flown into Porto and then travelled down by train.
