To know the physical traits of the seabed is one of the main tasks of the Hydrographic and Oceanographic Service of the Navy, to stablish safe navigation routes along the vast Chilean coastline.

The incorporation of the Hydrographic Survey Boat "LH-02" to the Hydrographic and Oceanographic Service of the Navy (SHOA) was made official in a ceremony led by the General Director of the Maritime Territory and Merchant Marine, Vice- admiral Mr. Osvaldo Scharzenberg Ashton, on December 11, at the Club de Yates de Higuerillas.

During the ceremony, the Director of the SHOA, Rear-admiral Patricio Carrasco addressed the contribution that this addition means to the duties of the Service. "This new vessel features cutting-edge hydrographic equipment, which allows, among other activities, developing sounding tasks for a more detailed investigation of the seabed in areas close the coast, with depths that vary from 10 to 200 meters, where the access for larger vessels is harder and riskier."

Later, the Chaplain of the Escuela Naval, Father José Jarpa, blessed the new boat, and commended its crew to God and to Virgen del Carmen1, patron saint of the Armed Forces.

;After the ceremony, the authorities were invited to take a trip around the bay on board of the LH-02 to learn more about the characteristics of the boat.


The Hydrographic Boat “LH-02”, Defender, has an aluminum hull, a length of 8.2 meters, and maximum width of 2.6 meters. It can carry 3.713 tons and its engines allow a maximum speed of 46 knots. It can be transported by land or air, in cases when is not possible to sail to the required area. Its hydrographic equipment consists of a multi-beam sonar, a movement sensor, an SVP profiler probe and it can, additionally, work with a side scan sonar (SLR); all these instruments will allow obtaining more detailed information about the seabed, in areas closer to the coast, which will contribute to complement, even more, to the already existent information in the National Naval Mapping, produced by the SHOA.
