This is all about the near/far relationship, and the relationship of the boat to the land (and to the faraway boat). I say keep the foreground, or some of it.
A square crop of the right hand side might be nice, but I do like the vertical rock element, it would be a shame to lose it. Same photograph 30 seconds earlier would have been better! Or if you could have moved a little to your left to pull the boat visually left in the frame.
Good concept, not great but good. Much of the technical stuff is fine (exposure, focus blah blah), I don't see any substantial problems there.
