Windy and slightly disturbed night. Bob did his normal thing – lift anchor by hand (!) and sailed off the mooring whilst I was still in bed. The wind ran out after a while so we put into “rock bay”. This is a bay with no sand and no landing because of a military base – but the water is crystal clear. Swims lunch and jobs followed. We decided there was enough wind to sail to Bosa 18 m south. With a mixture of motor and sail we approached the bay of Bosa fringed by green cliffs – copper bearing?? The harbour entrance had grown a huge breakwater since our chart and pilot were published so we motored in to have a look at the newish marina and the castle and town in the distance. Our plan was to anchor so we motored round the corner to find a large bay with lots of beaches hundreds of people and their umbrellas and a multitude of windsurfers swimmers canoeists and ribs – it was like trying to anchor in Piccadilly Circus. It took a while because of the frenetic achtivity to anchor – but there was no wind. Suddenly the wind picked up and up and up. After half an hour it was gusting 28 kn – more chain was dropped – I thought the marina looked inviting…. About 8.00pm it dropped – but what will happen overnight?
