Dividers: drag from one point to another on the chart

Start a drag on a charted object or buoy and it snaps to it. The readout gives the true bearing (and magnetic, 7°W) from where you start to where you are, and the distance in nautical miles.

Skill 3 · Dead reckoningProblem 576004

Two legs from a 1235 fix: where is the 1310 DR?

At 1235 you fix your position 333°T, 1.9 nm from Mill stack. You steer 099°T at 4.3 kn until 1250, then 059°T at 7.1 kn until 1310.

Give the 1310 DR position as the true bearing FROM Gannet Rock daybeacon to the DR, and the distance. Courses are true and speeds are through the water; dead reckoning ignores current and leeway.

Tolerance: 2° and 0.15 nm (or 4 % of the distance).

Given
1235 fix	333°T, 1.9 nm from Mill stack
Leg 1	099°T, 4.3 kn, 1235 to 1250
Leg 2	059°T, 7.1 kn, 1250 to 1310
