Its unfortunate the pole was even there, because the composition is so nicely done as is. The reflections are important to this picture. Closer or further away wouldn't have been as good.
Not really. That's west side of the island, so the swell from the Atlantic is comming stright into the bay. The bay itself is maybe 50 meters wide, or even smaller and very rocky, and as you can see the entrance is full of rocks.
On the east side of the island there is nice pier. I'd advice to moore there.
My advice - not a good place to anchor!
