I forgot to put this following observation in my last post:
Calculate the stopping distances of a 219 ft,20,000 GT vessel with speeds of
5,10 and 20 kt.
Calculate the transfer ratio of the same size vessel at the same speeds.
You may see the difficulty in manouvering something this large.

Jared,do you really think commercial shipping was ever anything but highly
cost driven?Do you really think even the old wooden commercial ships were
all always in tip-top condition with a full compliment of crew?Do you really
think the training of ordinary seamen and officers was as intense or those
men were of higher calibre than today?If you do,then you have a really
romantic and distorted view of what it was like in the commercial shipping
industry at anytime.
Small boaters(anything 100 GT and under domestic we will consider small)are
mostly pleasure boaters and a good majority of them are clueless as to rules
and traditions.
Now George mentioned he sails the English Channel.George,that is likely(I
don't know myself)a very congested area.Are there traffic seperation schemes
with vessel size restrictions in the schemes presant in the Eng. Chan.?Are
most of your problems with merchies coastal or offshore?
Jared,reguarding the visit to the cruisers bridge you made.Was it when the
vessel was offshore with no vessels close or was it inshore on an approach?

George-


 I think it is a sadly undebated fact that commercial shippig today is
highly cost driven. Which means flags of convenience, rustbuckets, and the
fewest cheapest crew that can be legally carried in many cases. By this I
mean no insult to professional mariners, just to say that one must assume a
ship is not fully or capably manned simply because it is big.

 I have had the pleasure of a bridge tour on a medium-sized cruise ship, and
seen the bridge literally left empty for at least ten minutes. Ship on
autopilot, radar on, but no human present, no watch being kept from the
bridge.

 Give way? Simply not possible, when there is no one on the helm. Perhaps I
saw the one incident in a thousand, but it seemed routine for them.
