Not possible. You have to be far enough away that the angular size of the mast and Moon are roughly equivalent. Judging by the person's silhouette, that mast is in the 40-foot range. Let's do the math. The Moon's angular size viewed from the Earth is 0.52 degrees. To get something 40 feet tall to have an angular size of 0.5 degrees requires a distance of 4,583 feet. If that picture is real, it has to be taken from 0.87 miles away from the boat. There is no way you're going to take a picture from nearly a mile away and resolve details as fine as the cables on the deck railing with zero distortion, especially over water. All of that is ignoring the fact that the lighting isn't possible. There is no camera on Earth that is capable of taking a backlit photo and perfectly resolving the details of the Moon and the shadow side of the backlit subject. Try taking a picture of some friends indoors with a window/door behind them and see what I mean.
