🔍 Key Concepts

• Cross bearings and lines of position (LOPs) from two known objects to find your fix on the chart • How to determine whether you are left/right of track relative to a desired course line between two points • Determining whether Inland or International Rules of the Road apply in Block Island Sound / off Watch Hill and Block Island

💭 Think About

• Plot the 323°T bearing from Watch Hill Point and the 084°T bearing from Block Island North Light as lines of position on your chart. Where they cross is where you are—what does that tell you about each choice? • Compare your plotted fix with the track or rhumb line you would normally steer between the two points. Are you above it (north) or below it (south)? • Look at the charted depth (soundings) at your fix and the charted boundary between Inland and International Rules in that area. Which statements could be ruled out just by those two checks?

✅ Before You Answer

• Verify the correct direction of plotting: remember bearings are given from your vessel to the object, but on the chart you draw the reciprocal bearing from the object toward your vessel. • Check the scale and distances: after plotting, measure the distance from your fix to nearby features (like Sandy Point) and compare to the number given in the choices. • Confirm on the chart whether the area around your fix lies inside or outside the demarcation line between Inland and International Rules; eliminate any option that conflicts with that.
