Not necessarily. Hen and Chicks would be very difficult to see. Blocked by Molly Beday and Pelican rock. The Groupers are not that easy to see either from Oyster Pond. With St. Barts behind them, it would be difficult to see them as individual islands.
Philippe is correct. What they are seeing is Statia, St. Kitts and Nevis although Nevis is seldom able to be seen anywhere in St. Martin on any but the clearest days. Maybe 2 times per year.
