Ship length? Bah!

Plot the target position on the map. Wait three minutes. Plot the target's new position on the map. Measure the distance in yards, divide by 100.
You now have the target speed in knots, without knowing the length.

By plotting it out on the map, you also figure his course, bearing, AoB, range, etc. A good plot is key to the targeting problem.
