• a vessel configured for trailing suction dredging, the vessel comprising:
• a hull including a bottom, bow portion, stern portion, port side and starboard side;
• a deck supported by the hull;
• a pump system mounted within the hull;
• a drag arm pivotably coupled to the pump system, the drag arm including a drag head configured to dredge an underwater surface while the vessel is underway;
• and
• a void defined by contiguous watertight walls or bulkheads joined to and extending between a first contiguous aperture in the bottom of the hull and a second contiguous aperture in the deck,
• wherein the first contiguous aperture and the void are dimensioned to accommodate pivoting of the drag arm from a raised position to a lowered position, the drag head being within the void when in the raised position, the lowered position being an active dredging position.
