Another windy day, we were moored stern to and the wind blew the bow away continually so we needed many warps to stop us banging the boat next to us. We spent the day in museums and boat maintenance. The salt museum was a history of the town and how they made salt from sea water in drying ponds. The nautical museum had a gunboat and a submarine that we visited. The submarine reminded me how I could never have been a submariner. One shower for a crew of fifty five people at sea for weeks would be very smelly and hot bunking to boot. The Spaniards are very proud of their submarine heritage despite the subs being sold to them by the USA.
