- Q107 - Navigation Problems: Chart Plot
42. The following questions should be answered using Chart 12354TR, Long Island Sound — Eastern Part, and the supporting publications. You are on a coastwise voyage from Bridgeport, Conn., to Boston, Mass. You intend to divert to a position off New Haven, Conn., to evacuate an injured crew member. Your height of eye is 53 feet and your vessel's deep draft is 34 feet. Gyro error is 2°W. Use 14°W variation where required. At 0820 Old Field Point Light bears 206° per gyrocompass, and Stratford Shoals Middle Ground Light bears 322° per gyrocompass. The radar range to Middle Ground Light is 1.5 miles. What is your 0820 position?
The correct position is determined by converting gyro bearings to true bearings, plotting reciprocal bearings from charted lights, and combining these lines of position with a radar range circle. Plotting these elements on Chart 12354TR reveals an intersection at LAT 4102.5'N, LONG 7304.9'W.
