Long Range Acoustic Hailing Devices, more commonly known as LRAD, enable vessels to hail, notify and warn approaching vessels at significant ranges with clear voice or prerecorded messages in any language.
California based LRAD Corporation is a Global Leader in the production of Long Range Acoustic Hailing Devices. The company provides vessel/platform operators the ability to determine the intent of a potential threat, such as a piracy event, at the earliest possible moment and at the greatest distance.
LRAD in Anti-Piracy
According to the International Maritime Bureau, during the first six months of this year alone there were 196 confirmed pirate incidents globally. Of those incidents, 31 resulted in completed hijackings with 544 crew taken hostage. There still remains 360 crew members being held hostage as of June 30, 2010.
LRAD enables vessels to hail, notify and warn approaching vessels at significant ranges with clear voice or prerecorded messages in any language.
In Novermber 2005, the luxury cruise liner Seabourn Spirit employed LRAD to repel a pirate attack off the coast of Somalia. The pirates did not succeed in boarding the vessel and eventually fled.
M/V Resolve & Sunshine Sky
Repelled Pirate Attack at 1100 Meters. “aimed her (LRAD) using the sight, went to maximum power and volume and activated. The first time the boat seemed to fall off course momentarily, then come back. I activated the unit a second time, this time holding it for a longer period and “waving” it across the target to make sure I “hit”. The boat instantly went dead in the water and broke off its attack. The range was estimated at .6 to 8 nm. The crew all saw it and they were cheering. I now have a ship full of believers. Lessons learned: It works.”
– Captain M/V Resolve
Repelled Swarming Pirate Attack at 250 yards. “There was a group of 5 small speed boats disguised as fisherman. Then two of them took off towards us. The captain called the mate on the radio to get the LRAD over to the port side. Once the boats got within 1 mile of the ship we turned on the LRAD. The speed boats got within 500 to 250 yards of the ship before stopping.”

Cable Laying Vessels
“By the way our ship … has had to use her LRAD’s 4 times in the last week to warn fishing vessels to remain clear of our cable track. Each time the fishing vessels responded immediately. We are using a warning we had translated into Egyptian when we hail them.”
