Yonks ago I was down at Maldon wandering along the quay there. A lovely estuary with a couple of barges and some other boats to be seen. Most of this part of Essex is low lying estuary filled with the yachts of the wealthy. At least you need to be wealthy to buy one of these things and then learn how to drive one. There have been such craft sheltered around here for generations, indeed one reason the Romans chose Colchester as their home was the ease of boats from Rome trundling up the river and almost into the town. The yachts are a wee bit more sophisticated today but admirable as they are I refer something with a bit of character and this Tugboat suits me more than an expensive boat.
Now I realise you are indicating somewhat caustically that the last time I was at sea was standing on the old bridge at Leith harbour and even then I felt seasick however I would like to dream about being a sailor! The crossing off the oceans, on a quiet day that is, would be enjoyable I say. Slowly cruising past Greek Islands, wandering about the Indian ocean, or viewing the landmass of Australia - from a distance, would be intriguing. Actually all that on a small cruise ship, with good lunches and competent crew, might be better than slogging around on an old tug. The only problem with cruise ships as far as I can see would be the other passengers!
Ho hum, I must go and dream on....
