Good on you, Jason. Encourage us like that and lots might come out! :-)
I am on a small cat cruising list and recently posted the following. See
how you go with it.
Cheers

Hey there cruisers,
With Cyclone Larry just ashore with winds of up 300kph it is a timely
moment to revise matters to do with meeting a cyclone at sea.
Imagine this....
You are sailing somewhere between the Solomons and Queensland. You hear
of a cyclone building over the SPCZ. The wind starts to build. Waves get
higher, and one dumps in the cockpit of your catamaran, sending water
inside, killing all your electrics, weatherfax, radio, radar, GPS,
laptop, EPIRB, the lot.
Bugger!
You only have left a compass and a barometer.
Exam:
A) If you face the wind, the cyclone eye is:
1. On your left
2. On your right
3. Straight ahead
4. Looking at you.
B) You measure the direction of the wind as 270ēM. After 30 minutes it
is 280ēM.
1. The wind is backing.
2. The wind is veering.
3. You are in the Dangerous Semi-Circle.
4. The compass is deviant.
C) You measure the barometric pressure as 1005 hectopascals. After one
hour it is 1000 hectopascals.
1. The eye is approaching.
2. Who's worried, you still have a grand of hectopascals left.
3. You must be in the Dangerous Quadrant.
4. You will go down the plughole clockwise because of the Coriolis
effect.
D) You establish that the wind is veering and the barometer rising. You
should:
1. Reach on the starboard tack.
2. Reach on the port tack.
3. Run down wind with a drogue.
4. Call for help on your Hadley cell phone.
E) You establish that the wind is veering and the barometer dropping.
You should:
1. Reach on the starboard tack.
2. Reach on the port tack.
3. Beat to windward on the starboard tack.
4. Set a course for the Madden Julian Oscillation.
F) You establish that the wind is backing and the barometer rising. You
should:
1. Reach on the starboard tack.
2. Reach on the port tack.
3. Beat to windward on the starboard tack.
4. You are in the Navigable Semi Circle.
G) You establish that the wind is backing and the barometer falling.
1. Reach on the starboard tack.
2. Reach on the port tack.
3. Beat to windward on the port tack.
4. You are in the Dangerous Quadrant.
I will send the correct answers out shortly, together with an explanation.
Please send in your entries asap. Honour and glory will go to the first
correct answer.
Cheers
Dave
