hmm... the boat at the lower left makes a very weak foreground subject. It lacks some punch. I would prefer to put the whole boat into the frame if possible.
And the hash light of the afternoon sun makes the bottom of the boat lose detail. It makes the photo looks very flat, lack the 3D feeling. One suggestion is to use the flash to fill-up the shadow, or wait for better timing.
actually imho, the 'cropped off' boat is fine... just that i find the shore disturbing....
try covering the shore with your hand and imagine that the shore is the lake..perhaps you will see why
