Page 50 Lake Ontario Offshore Racing Guide GMDSS is a very important safety system that can be used by sailors, whether cruising or racing, around the world. GMDSS is something that any ii, iii sailor should learn about There is one more component that uses MMSI and that is AIS. AIS, or Automatic Identification System, transmits data about a vessel, including; MMSI, vessel name, course and speed. Receivers can display the text of the data received or display them on a chart plotter/Multifunction Display. This data transmission was designed and implemented to help collision avoidance. AIS equipment can calculate the Closest Point of Approach (CPA) and Time to Closest Point of Approach (CPA). AIS alarms can be created when either CPA or TCPA is below the set threshold. This information can certainly help with determining avoidance while lowering the adverse impact to the race because of the long lead time. Both receive-only and receive/transmit AIS units are on the market. There are various classes for AIS transmitters depending whether AIS is mandated or optional on the vessel. If you are thinking about installing an AIS transmitter, you should really research AIS because of the various options and configuration that are possible. Consult a reputable marine electronics dealer. Many LOOR racers are installing AIS either receive-only or active to help with navigating safety across the commercial traffic lanes. There are web and smart phone apps that provide tracking of AIS transmissions 2. One tie-in between MMSI, VHF-FM Marine Radio and AIS is the fact that the MMSI of the nearby vessel is included in its AIS transmission. If you want or need to make radio contact with a nearby vessel with an AIS transmission, you just use the DSC feature of your radio including the MMSI of the vessel and their radio will react to it. You never know when this might come in handy. During a course at the Humber Bay Sailing Centre on Electronic Navigation presented by long time world cruisers, Ken and Carol Gillstrom, mentioned three ways to attempt to get the attention of that nearby big ship on the radio, R Put out a call describing the vessel and asking them to response. R Not much chance of a response R Put out a call to the ship by name obtained from AIS. A little better chance of a response R Put out a DSC call with the vessel’s MMSI obtained from AIS. The best change of a response. If you are participating in a LOOR Category 3 race, you are required to have a 25-watt VHF-FM marine radio, under the LOOR Offshore Special Regulations (OSR) {3.29}iv,v, the safety requirements. If it is DSC capable, you are required to have a MMSI. 2 For a list see the web site https://www.marineinsight.com/know-more/top-8-websites-to-track-your-ship/
Lake Ontario Offshore Racing Guide Page 51 When you register for any of LOOR’s events, one of the questions asks for you to enter your MMSI number. Please supply this for your safety sake. The steps for obtaining and making use of the free MMSI are simple and straight forward. 1. Submit a request for MMSI to your country’s issuer a. Canada see https://www.ic.gc.ca/eic/site/smt-gst.nsf/eng/sf01032.html b. USA see https://www.wikihow.com/Get-an-MMSI-Number 2. Once you receive your MMSI, follow the instructions for your VHF-FM Marine DSC radio to install the MMSI. There are complications if you fail to do so in three attempts or the radio already has a MMSI 3. If necessary, cable the GPS to the radio as defined by both devices instructions If there are any changes about the information included in the MMSI, such as vessel change, your details, etc., you need to follow the necessary steps to ensure everything is accurate and up-to-date to ensure the MMSI will do what’s intended when its used. For the DYI racers, and others interested in AIS, there is an interesting and useful article in the UK magazine, Practical Boat Owner’s February 2019 issue, “See and be seen” on page 62. vi Of course, everyone operating a VHF-FM marine radio, fixed or hand-held, on your vessel is required to have a Restricted Operators Certificate (Marine), which is a legal requirement. 3 So, go ahead and obtain your FREE MMSI which is required for LOOR Category 3 events and extremely useful throughout the season. LOOR would like to thank the Joint Rescue Coordination Centre, Central & Arctic Canada (JRCC C&CA) at Trentonvii and Canadian Coast Guard Prescott Marine Communications and Traffic Services Centreviii for their support and help with LOOR races. i http://www.ccg-gcc.gc.ca/eng/CCG/SAR_Gmdss ii https://www.navcen.uscg.gov/?pageName=GMDSS iii https://www.amsa.gov.au/safety-navigation/navigation-systems/global-maritime-distress-safety-system v https://docs.wixstatic.com/ugd/27634c_67476ea6f468467cbe65aefc6aeb6b17.pdf v https://docs.wixstatic.com/ugd/27634c_72771d6f9af5492b8d38cbe009b49934.pdf vi Berry, David, See and be seen, page 62, Practical Boat Owner February 2019 www.pbo.co.uk vii https://sarcontacts.info/contacts/jrcc-trenton-central-canada-only-6023/ viii http://www.ccg-gcc.gc.ca/eng/CCG/Notship#central 3. https://www.tc.gc.ca/eng/marinesafety/oep-navigation-radiocomms-faqs-1489.htm
