2. Slide 2 Summary  Electronics  Traditional Piloting and Charting Charts and Publications  Special Navigation Harbors Inlets Bridges Dams and locks

3. Electronics  Many electronics aids are available  For dependable performance, redundancy is the key (both electronic and tranditional)  New developments facilitate manual steps in the navigation process  Not a subsitute  Complementary Slide 3

4. Electronics  Depth sounder/SONAR Instant view of water depth Useful for shallow channels, anchoring, and navigation  Speed/Knotmeter Provides speed through water reading In comparison with speed over ground, can help determine wind and current effects  Global Positioning System (GPS) Provides essential locational information Can serve as a knotmeter providing speed over ground Slide 4

5. GPS Unit Slide 5

6. Electronics  Computer assisted navigation Computer use onboard Protection necessary unless waterproof and shock resistant  Chartplotter Combines GPS and charts in an electronic form Realtime view on chart  Radar Provides view of other boats as well as fixed objects Provides view of precipitation and severe weather information Some objects and boats do not give a return: lookout is still vital Slide 6

10. Traditional Piloting and Charting  Navigation on inland and coastal water is challenging  Charts, and use of them, is essential NOAA website offers up-to-date charts Coast Pilots Reed’s Nautical Almanac Eldridge Tide and Pilot Book  Binoculars  Compass Slide 10

11. Essential Tools Slide 11

12. Special Navigation  Harbors Commercial traffic can be hazardous to the recreational boater Research large harbors before visiting. If visiting, ensure you understand areas that are open and allowed for anchoring or tying to the quay.  Inlets and overfalls Meeting currents create rough and dangerous surf If leaving a coastal harbor, ensure you know tides and monitor wind direction Slide 12

13. Special Navigation  Bridges Drawbridges (Bascule bridge on charts). Check schedule for drawbridge before encountering Bridge tender monitors channel 13. Research charts and other cruising guides for bridge heights along your route.  Dams and locks Locks used to bypass dams and weirs. Lockmaster is in charge. Priority order for vessels; recreational vessels have the lowest priority for entry into locks. Slide 13

14. Bridges Low bridges usually have guages to indicate clearance Slide 14
