We have it made in North America. Ample number of lakes, rivers and of course the oceans to frolic in. The UK of course is surrounded by the sea but inland there are lots of rivers and streams but you may have noticed the canal that the narrow boat is moored in. The water appears to have little flow and the color of it is not great.
One thing that my inlaws mentioned when they rented a narrow boat in the UK twenty years ago is if you fell in the water the quality of the water left a lot to be desired. A lung full of that stagnant crappy water could be the end of you and not necessarily from drowning.
Thanks for the video Rod. That was interesting.
