My favorite is #3. It has the most compelling composition, as you have isolated the most essential elements of the scene and arranged them so that each not only presents its own visual imapact, but leads to and supports the other elements.
In the pictures with multiple masts, I feel some distraction and confusion. I have frequently wrestled with that type of picture, often with a wish to convey the busy quality of the many boats, but ended up with duds that simply appear too busy. #3 has an elegance that the others don't.
