you have good clarity but your tone is very dull and flat...a gradient would have helped that and pushing your hue/saturation before you converted it to B&W would have done that as well
I have taken this shot a few times.I have never actually thought to do it as a black & white until now. This works very well & I like the fact there is only a single yacht.
Not a fan of the border, I feel if you were going for this design, then I would have used black and not grey for the outside.............
Apart from that, The composition is good and the B&W processing is very good.
