18 Oct: Set off at 7am in the dark and the fog and crept out of Aveiro estuary. We saw a pilot boat heading out so we knew to watch out for a large vessel and sure enough we saw one through the fog shortly afterwards and kept well out of its way! The fog lifted as it got light but there was no wind, so we motored in the mist all morning. We had more dolphins swimming with the boat, this time about twice the size (about 2 metres) so probably bottlenose. They had great fun trying (successfully at times) to soak us by doing back flips and slapping their tails on the water! The wind picked up in the afternoon, so much so that we had a fishing boat shadowing us (rather too close for comfort) in order to get shelter from the wind on the way into harbour! We berthed in Nazare marina after 12 hours and 71 nautical miles.
