This image does convey dead end, but I feel that the soft focus and blown out sky distract from the 'dead end'. In this case moving the camera such that it doesn't have the sky in the shot, maybe just the tree line behind it would help the viewer stay at the dock rather than the bright sky moving their eyes away from it.
I like how the angle has the view over the water and off the pier, it creates motion in the image by having the viewer feel like he/she is falling... The sky does seem a bit oversaturated and in places overexposed...
