Bay of Firth (Day 620)

I missed out on the morning wander with the dogs this morning,  my beautiful wife wanting to make an early excursion to Stromness and the horses.
I trundled off to town for some bits, then to a little job. Later on I headed to the macerator job again and fitted the new parts. It still doesn't work.
After lunch, and a brief study of the map, I went out for a cycle. 15 miles, 1069 feet of elevation gain, average speed 12.5mph, total time 1 hour 11minutes and 54 seconds. I am really pleased with that, and that I wasn't dead at the end of it.
I stopped briefly to take a snap with my mobile phone looking over the Bay of Firth. I have no idea what the thing that looks like a warship is.
