Rescue 21 continues to revolutionize SAR

Position? Nature of distress? Description of the vessel? Number of people on board? Are people wearing their life jackets?

These are the first five things a Coast Guard watchstander will ask when you make a distress call. Watchstanders call this data, “the big 5,” as they are vital pieces of information needed during a search and rescue case.

A vessel’s position is the most crucial piece of information but sometimes the hardest to determine. Yesterday, ending a two year phase-in period, Coast Guard Sector Baltimore formally accepted Rescue 21, a new tool to help watchstanders determine a distressed mariner’s position.

Rescue 21 is already covering more than 35,000 miles of coastline in the United States and, as of yesterday, officially includes the coasts of Maryland, Virginia, Washington, D.C., and the upper Chesapeake Bay.

Rescue 21 put to the test

Recent search and rescue cases in the area exhibit how valuable Rescue 21’s advanced capabilities can be.

On July 25, watchstanders at Sector Baltimore put Rescue 21 to the test as they responsed to 37 distinct distress calls, resulting in more than 77 people assisted or rescued – all in only a two-hour period.

An unexpected powerful storm suddenly erupted in Chesapeake Bay on a calm summer day, producing wind gusts and volatile sea conditions and catching mariners off guard. Mayday calls began pouring in to the Sector Baltimore command center. Using information gained from Rescue 21, watchstanders were able to determine locations of the distressed mariners and launch Coast Guard assets from six different small boat stations to respond to the calls for help.

Chief Lawrence Beatty, an Operations Specialist at Sector Baltimore, was first introduced to Rescue 21 eight years ago as part of a test bed, when the technology initially launched. Beatty is very familiar with the benefits Rescue 21 provides command center watchstanders.

“Right off the bat, a watchstander has a visual display so you are not only hearing the transmission but you are also seeing which towers are picking it up and in which direction,” said Beatty. “The towers are strategically placed so multiple towers can pick up and triangulate to where that mariner is.”

In a sense, Rescue 21s direction-finding capabilities, as well as its increased range, allows command centers to better “hear” the call.

For a mariner in a dire situation, reaching for a handheld radio and calling “Mayday” over marine radio channel 16 may be their only chance for getting help. Even with just that single call over the radio, Rescue 21 can help watchstanders piece together the information they need, specifically a position, to send response resources to the mariner’s aid.

Radio or cell phone?

At a time when boaters have become over reliant on cell phones, Rescue 21 drives home the value of carrying a radio on your boat.

“Mariners who are reliant on their cell phones because they have a signal get that false sense of security,” said Beatty. “While we can get a rough area of where you are with your cell, we can find a more specific triangulated position with a marine radio.”

Incompatibility with Rescue 21 is not the only limitation of cell phone communications on the water. Inconsistent cellular coverage, limited battery life and no direct link to Coast Guard rescuers are a few others.

VHF channel 16, the International hailing and distress frequency, is the best and quickest way to reach emergency resources. Not only are Coast Guard rescuers listening to channel 16, but so are most other mariners. Instead of a one-to-one call on a cell phone, the VHF radio provides a one-to-many call… because sometimes the closest assistance is another boater nearby. Boaters and others who recreate on or near the water should always carry a VHF marine band radio and use channel 16 – no exceptions!

Rescue 21 will continue to be installed throughout the country greatly enhancing the Coast Guard’s mission execution and effectiveness. You can follow the progress of the program here.

    Rescue 21 sounds great BUT I’m a retired Coast Guard Telecommunications Specialist. I left the Baltimore command center over 8 YEARS ago & we were working then on becoming one of the test sites. NOW it’s fully operational at Baltimore and STILL not deployed throughout the Coast Guard? How much longer before we’ll be fully deployed nationwide with technology that’s a decade old!!!. Can government not do anything efficiently. Even when lives are at stake??

    Bill,

    Take a quick spin over to the Rescue 21 website ((http://www.uscg.mil/acquisition/rescue21) and check out their deployment map (). Rescue 21 is up and running along almost all the coastline of the US. The team has done a tremendous job with deployment over the last several years and the technology works as demonstrated by the article above and continuing stream of new stories highlighting incredible Rescue 21 rescues. As with most things, I think we all would like the CG to deploy everything quicker from cutters to Rescue 21, but the CG doesn’t have an unlimited source of funds to acquire everything at once and the intricacies of Rescue 21 deployment from planning to addressing environmental issues to securing leases are complex and take time. They do a great job and work tirelessly behind the scenes to get Rescue 21 out as fast as possible.

    All,

    I would also highlight the Digital Selective Calling (DSC) feature of Rescue 21 (). DSC isn’t just for commercial craft, it’s available on many VHF-FM radios including handhelds. Properly connected and registered, you can transmit a burst digital message transmitting the radio’s GPS position and caller identification, letting the CG and anyone else in the neighborhood with a DSC radio know exactly who and where you are before you can say “mayday.” Hand-held radios available for under $200 and THAT’s an insurance policy worth buying.

    Team Compass,

    Thanks for keeping the blog alive and interesting!

    Also, Rescue 21 cannot be used everywhere in the US because of the nature of the curvature of the Earth. For example, Alaska has shown to not have reliable Rescue 21 performance because of that. I think it’s great that Rescue 21 is almost lower 48-state wide, and I am definitely from the R21 generation of SAR controllers!

    Everytime I teach a Boating Safety class for the Coast Guard Auxiliary I stress the need for a radio on board. Rescue 21 is usless if the boater does not have a radio with dcs and to a lesser extent a gps attached to it. Also, is the CG putting up enough towers to cover its whole area of responsibility?

    Mel;
    Actually, neither DSC nor a positioning source is required for R21 to be extremely benificial. Actually with DSC and a posit source the “R21″ major portion isn’t needed. R21s biggest benifit is actually for those radios without those two things. For the first time, we have the ability, with R21, to determine reasonable a searchable area. Between visual displays of ‘lines of bearing’ of the transmission as well as other capabilities, the watchstanders ability to help the mariners is greatly increased.
