Increasing the tension in a picture
The landscape view
I liked this view of the boat, looking at it from below against a blue sky is an effective device.
Isolating the prow of the ship and including the mooring lines in the frame helps create a simple composition.
There is literal tension from your knowledge as a viewer that the mooring lines are stretched taut:
The Portrait View
I like this view even more.
Using the portrait format allows an even more dynamic view.
The tension in the picture is increased because including more of the mooring lines makes it look as though the ship is rearing upwards trying to pull free from its restraints.
