A photographic study: Colour versus B&W

As I continue to explore photography from various angles,  the impact of colour is one of the obvious subjects of interest. And I thought I put this to the test by looking at the same image in colour and black & white.  Now, I would be very interested to hear your opinion. Which image does have a stronger impact for you? My last post which was published in colour, or its black & white version?

Landscape

What caught my attention in this landscape was the human influence on the landscape. A contrast which I noticed I often try to avoid in my photos as I feel drawn to nature and its wonders. This picture in contrast has been marked by the presence of the boats.
