at all times and just clear the lower end of the Lintin
Bar at high tide there.
You will doubtless be wondering how many
vessels in the world will be prevented from visiting Whampoa when the channels are dredged to the depths
mentioned. our studies have answered that questione
From the data taken from Lloyd's Register it is estimated
that only ten percent will be prevented from coming
every day. During the spring tides which occur every
month this is reduced to four percent.
another common question is what vessel tonnage
this indicate. Ho defialte fi ure can be stated because
vessels are built with very great differences in design.
The answer has to be a qualified one. at least two vessels
exist in the world which are only of about 3,000 net tons
capacity which draw to, much water ever to come to haram
poa, while at least one vessel with a net register of
15,500 tons could come up to halpos, even were the channel to be only 28 feet deep.
These vessels listed by Lloyd's Navigate sail
on all the oceans of the world.
hat about those which
visit Rong Kong? of the latter, 91 percent will be able
to come to hampos at all ties, and 99 percent can come during spring tides. To provide for that last une percent would require five feet more depth, which would cost
roughly six million dollare extra.
Similar studies have been made of the proper
chunnel widths, and it has been determined that the chan-
nels through the Piret and Second Bars should be 70 meters
or 130 feet wide, whil- that through the Lintin Jar should
be 100 wetere or 530 feet in width. These dimensions will
peruit the average vessels to pass each other with ample
clearance and even the widest ones can pass with vary
little extra care under normal conditions of wind and
tide.
