A comprehensive resource for safe and responsible laser use
The following is from a Coast Guard press release dated May 4 2017:
The Coast Guard is investigating multiple laser strikes during the past month aimed at commercial vessels transiting the Chesapeake Bay and warns the public of this dangerous act.
Four incidences occurred early Wednesday morning between midnight and 3 a.m., involving the motor vessels Salome, Bulk Spain, and AM Annaba. Additionally, a pilot vessel was lased as it was on its way back to the pilot launch.
Three other incidents occurred: Monday around 2 a.m., involving the motor vessel Hoegh Osaka; Sunday at 4 a.m., and involved the cruise ship Carnival Pride and another April 7 at approximately 1 a.m., involving the motor vessel Maersk Kolkata.
During all incidents, the laser light was described as steady, powerful and somewhat painful to the eyes. The reporting source believes the laser originated in the area between Drum Point and Cove Point, and lasted for approximately 15 minutes.
“Laser lights, and other bright lights can be a hazard to navigation,” said Lt. Trish Elliston, Coast Guard Sector Maryland-National Capitol Region. “The most likely scenario is the laser would blind or distract a pilot which would prevent the pilot from seeing a smaller vessel. This could cause a collision or other serious incident in the shipping channel.”
The Laser Safety Act, makes it a misdemeanor to knowingly and willfully cause or attempt to cause bodily injury by shining, pointing, or focusing the beam of a laser pointer on an individual operating a motor vehicle, vessel, or aircraft. The penalty is a maximum 10 years in prison and a fine of up to $2,500.
The Coast Guard is working with state and local law enforcement along with Chesapeake Bay Pilots to investigate the incidents. Anyone with information leading to the whereabouts of the individual, or individuals, involved are asked to contact the Coast Guard Sector Maryland-National Capital Region Command Center at 410-576-2525 or via email at email@example.com.
Raden also pleaded guilty to reckless endangerment in Island County Superior Court. He was ordered to serve 15 days in jail, perform 240 hours of community service, pay $3,740.89 in restitution to the master and chief mate, and serve 24 months probation.
On April 26 2016, the Coast Guard issued a civil penalty of $100,000 against Raden. According to a Coast Guard press release at the time, “Coast Guard officials are seeking civil penalties for violation of a safety and security zone as well as interference with the safe operation of the Tokitae [ferry] while it transited between Mukilteo and Clinton [in Washington state]. The final civil penalty amount [which turned out to be $9,500] will be determined by a Coast Guard Hearing Officer in Arlington, Va.”
A Coast Guard spokesperson told Cyrus Farivar of Ars Technica "Originally there were multiple charges that brought the maximum amount to $100,000 [as] referenced in the original [press] release. Ultimately the hearing officer has the final say and chose to only pursue the one charge for 'interfering with the safe operation of a vessel' and assessed a fine of $9,500."
Raden has previously been in trouble for misusing a laser. In July 2015, Raden and his friend Dillon Reisman, 27, were aiming a laser into house windows in Langley, Washington, in order to “cause alarm to anyone trying to sleep.” When confronted by police, Raden repeatedly aimed the laser beam into an officer’s face. Felony charges were not filed until November 18 2015.
In yet another incident, police said Raden was accused of using a laser and acid as weapons.

This map shows the ferries’ route. The map’s indicated positions of the ferries are from a later time and do NOT show their position during the laser incident.
At about 8:30 pm, the ferry M/V Tokitae (shown below) was approaching the Clinton (Wash.) Ferry Terminal. The captains were at wheelhouses on opposite ends of the 362-foot-long ferry. The one piloting the vessel was hit first, and suffered injuries.
According to Washington State Ferries Port Captain Jay Mooney, the man had “third-degree burns on his eyelid and his vision is still not quite back at 100 percent.” (A first-degree burn occurs only on the surface of the skin. A third-degree burn “extends to all layers of the skin,” according to the Wikipedia “Burn” article.)
The blue laser beam came from the slightly smaller ferry M/V Kitsap, which was traveling in the opposite direction.
A Kitsap deckhand had seen two men with the laser, and reported it to a Washington State Patrol trooper after arrival at the terminal in Mukilteo. One man told the officer that “it was a new toy and he was shining it at the water and didn’t mean to shine it at the vessel,” according to a WSP spokesperson. The trooper confiscated the laser pointer, shown here:
The spokesperson said “This is not a typical laser you’d see in a classroom or office setting.” She referenced the manufacturer’s packaging which says to use safety glasses, to not aim it at faces, and that it could light a match if held on target long enough.
A similar-looking laser sold by Lasers-Pointers.com is said to be 5000 mW (5 watts) and costs less than $200:
The two captains exposed to the laser light missed one day of work. The suspect who had the laser has not yet been charged, as of October 29 2015. Prosecutors are determining what charges would be appropriate.
UPDATED - November 9 2015: No arrests have yet been made and no charges have been filed, more than two weeks after a suspect was picked up. This is due in part to determining what jursidiction applied, since the laser incident took place on ferries in waters between different Washington state counties. Another difficulty was determining what charge to file. A KIRO radio story also noted the limitations of the U.S. Food and Drug Administration, which regulates lasers. While FDA attempts to block some high-powered lasers, imports can get through. And, “there aren't any penalties for buying or owning those illegally high-powered devices, nor are there requirements for training for non-medical, non-industrial devices.” From MyNorthwest.com
UPDATED - April 18 2015: 27-year-old Mark Raden was charged with assault in the third degree, for aiming at the ferry captains. In addition, he has a previous history of run-ins with law enforcement over laser misuse. Details are here.

Coast Guard boatcrew targeted with laser near Clearwater, Fla.
ST. PETERSBURG, Fla. — A boatcrew from Coast Guard Station Sand Key was targeted with a laser from the shore approximately one mile southwest of Clearwater, Sunday [August 11 2013].
The station informed the station's watchstanders at 10:18 p.m., reporting the 25-foot Response Boat — Small boat crew experienced a three to four second blue, green laser burst while on patrol in the area. The entire crew experienced loss of night vision and half the crew received a direct hit from the laser.
The boat crew had to return to the station and receive eye exams.

A Harbor Police spokesperson told LaserPointerSafety.com “neither officer was injured in the latest incident” and “the laser used in this incident was much less powerful than the one used” in the May 4 2012 lasing, when two San Diego Harbor Police officers were taken to UC San Diego Medical Center after their boat was lased. One officer was said to have had a temporary injury in one eye.
Approximate locations of the lasers (green triangles) and Harbor Police boats (red squares).
Officers Jennifer McMaster and Robert Twardy were patrolling near the Shelter Island Fishing Pier when both illuminated directly in their right eye. Twardy said “I noticed that I had a bright spot, like a residual flash that you kind of get when a camera flashes in your eye.” He suffered a “burning sensation”. Both officers were taken to UC San Diego Medical Center.
Twardy said that McMaster had a more direct hit, was in pain, and complained of blindness. She had possible burns to her retinas, and took time off to recover, according to the Los Angeles Times. She will make a full recovery, according to an NBC San Diego story. [See Update 1, at the bottom of this story after clicking the “Read More” link, for more medical information.]

300 hours of community service for shining lasers on ferries
The judge said that while Long could have caused “significant” harm, he no longer lived in a house overlooking the channel, so “the chance of reoffending was unlikely.”
From the Marlborough Express. There are additional stories about Long’s guilty plea from the New Zealand Herald; about prosecutors being upset due to Long being given bail despite having “an arsenal” of 30 guns, also from the New Zealand Herald; and about the trial where the defense said persons other than Long were using the laser, from the Marlborough Express.
Condoleeza Rice, Secretary of State at the time, sent the cable to the U.S. Embassy in Beijing. Rice said that China’s actions were “provocative and inconsistent” with the law of the sea” and “constitute serious harassment and elevate the risk of miscalculation.”
Washington Times reporter Bill Gertz, who broke the story, was unable to find out whether the light was a laser or a high-powered searchlight. Gertz also pointed to parallels with the 1997 suspected laser use by the Russian merchant ship Kapitan Man.
From the Washington Times
Analysis: Based on the color, LaserPointerSafety.com believes it is a conventional light. To produce a white light beam with lasers requires superimposition of three or more single-color lasers. This is more difficult than using a single-color laser, and would not provide any significant benefit in a situation such as the ship attack. (If countermeasure anti-laser goggles are being used, then it may be beneficial to use multiple wavelengths. It is more difficult to defend against multiple wavelengths, and doing so would reduce conventional visibility since red, green and blue light would all be blocked. Even here, balancing the wavelengths to produce a “white” light is not necessary.)
