**Answers to Relative Bearings Practice Lesson**

1. Brenton Reef light bears 225° T. Your current course is 059° T. The relative bearing of Brenton Reef light is 166°. |

True Bearing – Ship’s Heading = Relative Bearing – 225 – 059 = 166 |

2. Cleveland Ledge Channel light bears 325° relative. Your course is 135° T. The true bearing to the Cleveland Ledge Channel light is 100°. |

Relative Bearing + Ships Heading = True Bearing – 325 + 135 = 100(Remember when adding, if your total is over 360° you must subtract 360°). |

3. Rudee Inlet light bears 035° relative. Your course is 156° T. The true bearing to the Rudee Inlet light is 191°. |

Relative Bearing + Ships Heading = True Bearing – 035 + 156 = 191 |

4. Moose head shoal light bears 224° T. Your course is 270° T. The relative bearing to the Moose head shoal light is 314°. |

True Bearing – Ship’s Heading = Relative Bearing – 224 – 270 = 314(Remember when relative is less than ship’s heading add 360° to answer). |

5. Hell’s Gate point light bears 270° relative. Your course is 180° T. The true bearing to Hell’s Gate point light is 090°. |

Relative Bearing + Ships Heading = True Bearing -270 + 180 = 090 |

6. The light at Keenan Point bears 066° T. Your course is 134° T. The relative bearing to Keenan Point light is 292°. |

True Bearing – Ship’s Heading = Relative Bearing – 066 – 134 = 292 |

7. Bull Shoals light bears 119° T. Your course is 235° T. The relative bearing to the light is 244°. |

True Bearing – Ship’s Heading = Relative Bearing – 119 – 235 = 244 |

8. The lighthouse at Judith point bears 340° relative. Your course is 080° T. The true bearing to the point Judith lighthouse is 060°. |

Relative Bearing + Ships Heading = True Bearing -340 + 080 = 060 |

9. The buoy marked R4 Fl 4 sec bears 115° T. Your course is 220° T. The relative bearing of the buoy is 255°. |

True Bearing – Ship’s Heading = Relative Bearing – 115 – 220 = 255 |

10. Muscle shoals danger buoy bears 145° relative. Your course is 190° T. The true bearing to the danger buoy is 335°. |

Relative Bearing + Ships Heading = True Bearing -145 + 190 = 335 |
