Quark Expeditions is set to enhance its polar expedition offerings by adding the Ocean Explorer to its fleet for the 2024-25 Antarctic season. The Ocean Explorer, a Polar Class 6 icebreaker, is part of the SunStone Maritime Group's Infinity class ships and is capable of carrying 138 passengers. This vessel, delivered in 2021, previously sailed for Vantage Deluxe Travel before the company ceased operations last summer. Following that, Aurora Expeditions chartered the ship.
