The speed of the boat, the spray, the water, the mountains & the sky are great - but the central band of the photo is cluttered - which is a shame because it takes the eye away from the best features.
This is a nice one, and definitely gives a feeling of speed. I wonder about the composition, though - I had to drag my eye down to the water to get the feeling of speed, since the land dominates the picture in terms of space, and yet seems irrelevant to it.
