The crew are spread out in the boat, with one even right up in the bow where you don't normally have someone sit on a boat of this size. It accepts this and carries on sailing. This video highlights how much space there is in this boat.
The Argie 15 is a great camp-cruiser, with a good turn of speed. That also makes it a nice raid boat, capable of taking rough water and covering extended distances.
