GENERAL DESCRIPTION:
The hull is catamaran design. The deck is flat, continuous from aft to fore, built with antiskid treadplates. In the fore is mounted a bulwark of variable height from 800 to 1000 mm. to protect the deck against the sea billows. The hull is of chine line type, the stern is transom and give location to two foldable platforms, one each side, to enable the divers activity.

N° 3 watertight bulkheads subdivide the hull in 4 compartments, one intended for the Engine Room location, the other to house auxiliaries and plants.
Each catamaran hull has one deep keel, suitably designed to shield propeller and rudder, where is located the stern tube and the rudder support keel.
The crane is arranged on the deck, foreward at starboard side.

A. HULL
