291 When are the dog watches?
og watch, in marine or naval terminology, is a watch, a
period of work duty or a work shift, between 1600 and 2000
(4 p.m. and 8 p.m.)
292 What is the purpose of the dog watches?
The reason behind this watch's existence is that in order
for the crew to rotate through all the watches it was
necessary to split one of the watches in half. This allowed
the sailors to stand different watches instead of one team
being forced to stand the mid-watch every night.
293 What is the origin of the term?
The name is thought to have come from the fact that someone
tasked with one of these 'half' watches was said to be
'dodging the watch', taking or standing the 'dodge watch'.
This became shortened to 'dog watch':running:

294 Who control the Signal Stations in Great Britain?
CHIEF OFFICER, ROYAL NAVAL SHORE SIGNAL SERVICE
295 What does "f.o.b." stand for?
FOB stands for "Free On Board", and is always used in
conjunction with a port of loading.[1] Indicating "FOB port"
means that the seller pays for transportation of the goods
to the port of shipment, plus loading costs. The buyer pays
cost of marine freight transport, insurance, unloading, and
transportation from the arrival port to the final
destination. The passing of risks occurs when the goods pass
the ship's rail at the port of shipment.
296 How many nautical miles are there in a degree? 60
297 What is a pelorus? : a navigational instrument
resembling a mariner's compass without magnetic needles and
having two sight vanes by which bearings are taken
298 What is meant by displacement tonnage? the actual total
weight of the vessel
299 And by deadweight tonnage?
the displacement at any loaded condition minus the lightship
weight. It includes the crew, passengers, cargo, fuel,
water, and stores.
300 And gross tonnage?
a function of the volume of all ship's enclosed spaces (from
keel to funnel) measured to the outside of the hull framing.:guinness::guinness:
