My wife and I just returned from a Caribbean cruise. The attached
page is info on the ship we were on, which us engineers find pretty
interesting. Just like train locomotives, the large diesel engines on
these ships drive generators, which in turn power electric motors, to
which are attached the propellers.
The info is clearly originally in metric units, and is translated to
colloquial units for us Americans (probably 70% of the passengers). I
asked the Chief Engineer which they use for general operations, and
he replied metric. However, they still use nautical miles and knots
for navigation. Seems odd to me.
Perhaps someone can explain the Gross Tonnage specification: metric
unit is tons, colloquial unit is cubic yards. I cannot figure that one out.
Couple more scans from this trip to follow.
