1 Boating Skills And Seamanship 1 Copyright 2007 - Coast Guard Auxiliary Association, Inc. Your “Highway” Signs Chapter 5

2 Boating Skills And Seamanship 2 Copyright 2007 - Coast Guard Auxiliary Association, Inc. Lesson Objectives Aids to Navigation (ATONS) Cautions around ATONS Meaning of chart symbols Electronic ATONS Reference materials – changes in ATONS

3 Boating Skills And Seamanship 3 Copyright 2007 - Coast Guard Auxiliary Association, Inc. ATONS How are ATONS essential for boaters?

4 Boating Skills And Seamanship 4 Copyright 2007 - Coast Guard Auxiliary Association, Inc. ATONS Help determine a safe course Help determine where you are Help navigate to reach destination Give information Are shown on chart

5 Boating Skills And Seamanship 5 Copyright 2007 - Coast Guard Auxiliary Association, Inc. ATONS Short range (Examples?) Long range (Examples?)

6 Boating Skills And Seamanship 6 Copyright 2007 - Coast Guard Auxiliary Association, Inc. ATONS Short range Buoys Daymarks/daybeacons Lighthouses Long range GPS Loran - C Radar

7 Boating Skills And Seamanship 7 Copyright 2007 - Coast Guard Auxiliary Association, Inc. ATONS What other landmarks are helpful to boaters?

8 Boating Skills And Seamanship 8 Copyright 2007 - Coast Guard Auxiliary Association, Inc. ATONS Anything visible from the water Towers Monuments Bridges Distinctive land formations Appear on chart

9 Boating Skills And Seamanship 9 Copyright 2007 - Coast Guard Auxiliary Association, Inc. ATONS ATONS are protected by law Do not: Alter Destroy Move Tie up to Climb on Obscure others view

10 Boating Skills And Seamanship 10 Copyright 2007 - Coast Guard Auxiliary Association, Inc. Buoyage System How are ATONS grouped into systems? Location Maintenance

11 Boating Skills And Seamanship 11 Copyright 2007 - Coast Guard Auxiliary Association, Inc. Buoyage System There are four Buoyage Systems in US US ATON System Intracoastal Waterway System Western Rivers System Uniform State Waterway Marking System merged into USATON System in 2003 Merge = adopted same aton patterns

12 Boating Skills And Seamanship 12 Copyright 2007 - Coast Guard Auxiliary Association, Inc. US ATON Principal system of the U. S. All Navigable waterways (empty to sea) except Western Rivers, & waterways crossing state boundaries One of two international standards. Used throughout N & S America, Caribbean, Japan, Korea, & Philippines. Remainder of world uses other standard (colors reversed) Maintained by the U.S. Coast Guard

13 Boating Skills And Seamanship 13 Copyright 2007 - Coast Guard Auxiliary Association, Inc. U.S. ATON System What are the six types of ATONS?

14 Boating Skills And Seamanship 14 Copyright 2007 - Coast Guard Auxiliary Association, Inc. U.S. ATON System Lateral Marks including Preferred Channel Marks Safe Water Marks Isolated Danger Marks Range Marks Regulatory Marks Special Purpose Marks

15 Boating Skills And Seamanship 15 Copyright 2007 - Coast Guard Auxiliary Association, Inc. Intracoastal Waterway (ICW) New Jersey to the Florida Keys along the Gulf of Mexico to Brownsville, TX Lateral marks are small reflective yellow squares and triangles Non-lateral marks, e.g. safe water and range marks, have reflective yellow band.

16 Boating Skills And Seamanship 16 Copyright 2007 - Coast Guard Auxiliary Association, Inc. Western Rivers The Mississippi River and it’s tributaries Need to study if you plan to boat it. Left descending bank; right descending bank Downbound has right of way Maintained by the U. S. Coast Guard

17 Boating Skills And Seamanship 17 Copyright 2007 - Coast Guard Auxiliary Association, Inc. Uniform State Waterway Marking System Merged with US ATON system by end of 2003. Maintained by individual states

18 Boating Skills And Seamanship 18 Copyright 2007 - Coast Guard Auxiliary Association, Inc. Uniform State Waterway Marking System Cautions “Merge” is to replace the ATONS which looked similar to US ATONs, but had different meanings. US ATON system added information marks, and a few others, needed by the states No affirmative confirmation that process was completed. Need to have good understanding of your location

19 Boating Skills And Seamanship 19 Copyright 2007 - Coast Guard Auxiliary Association, Inc. Waterway Marks/Buoys /Beacons Come in various sizes and shapes Daymark – signboard only Daybeacon – signboard & piling or dolphin Buoy floats, has watch circle May or may not have lights Mark channels, dangers, obstructions Provide regulatory information

59 Boating Skills And Seamanship 59 Copyright 2007 - Coast Guard Auxiliary Association, Inc. Electronic ATONS Characteristics Loran - C GPS Radar Reminder: don’t rely on a single navigation system.

60 Boating Skills And Seamanship 60 Copyright 2007 - Coast Guard Auxiliary Association, Inc. Electronic ATONS/ Loran - C Land based AM radio navigation system Largely American system Static Signal deflected by land mass & weather Translators now convert TD (time differential) to Longitude and Latitude About 100 foot accuracy System upgraded in 2005 Backup for GPS since not subject to same reception restrictions

61 Boating Skills And Seamanship 61 Copyright 2007 - Coast Guard Auxiliary Association, Inc. Electronic ATONS/ GPS Satellites provide nearly accurate world wide positioning Wide Area Augmentation System (WAAS) Uses waypoints to navigate. YOU must ensure course is safe. Chart plotter useful; must update charts Consider overlay RADAR on single monitor

62 Boating Skills And Seamanship 62 Copyright 2007 - Coast Guard Auxiliary Association, Inc. Electronic ATONS/RADAR Only real time electronic check for navigation hazards 2 systems: ship’s head up or north up May automatically ID collision course Electronic marks to track targets If you have RADAR you must use it. You will want the practice too.
