**Math Analysis**

From a ship off-shore, the angle of elevation of a hill is 1.1°. After the ship moves inland at 4.5 knots for 20 min, the angle of elevation is 1.4°. How high is the hill? (1 knot = 1 nautical mile = 6080 ft per hour) As I was just about to get the answer, I realized that it ...

**Nautical/Stability/GM**

I have previously understood a ship's GM determined her role period. However I have just read that if weight on the centreline of the ship is moved laterally outwards to the sides of the ship this will slow the ships roll ie. increase its roll period. I understand the GM of ...

**Nautical Studies**

I understand it is a popular misconception that a magnetic compass points to the magnetic north pole. In fact a magnetic compass aligns itself with the magnetic lines of force in its own location. Here in the UK these lines of force seem to coincide very closely with the ...
