junk designs encompass many families from flat bottom to multi-chine and round
bottom. I have no designs for V bottom junks. They fall basically into four
is a flat bottom junk with a
and leeboards. She is a good coastwise sailing vessel; however, when modified for yachting purposes, a
centerboard versus leeboards is a more practical solution for obtaining lateral plane. Most
are built with a shoal keel, eliminating the leeboards and centerboard.
Multi-chine and round bottom junks, based on the Hainan junks, range from 42
to 150 in length. The most popular ones are OOTHOON at 41(shown above), KUNG FU-TSE
at 48(shown at left), and LUK CHIN at 54 which have been built in both steel and
aluminum. The 54' junk has also been built as a round bottom steel hull. The
larger sizes are usually round bottom since, in larger sizes, most builders
prefer this type of construction and are equipped to handle the bending of
round bottom frames. These are excellent sea boats. The larger ones
incorporate daggerboards, while on the smaller ones used for yachting I have
substituted a long shallow keel which opens up the whole interior to an
infinite variety of arrangements. Most of them have made long voyages and, as
such, I like to keep the engine and fuel tanks very close to the center of
floatation and center of buoyancy.I
also use the engine room with bulkheads at each end to isolate all machinery.
This provides good working conditions around the engine.Most vessels have access doors for passage through the engine room;
whereas, in others the engine room bulkhead is not pierced and access is from
the deck only.
is an 18.5 meter (60) cargo
junk displacing 42 tons in ballast, which is under construction at the
present time in Timor. This family of cargo junks has a distinct type of hull
form that has no direct counterpart in China, but is a combination of several
types plus some modifications that stress performance to windward. They are
modest carriers and are primarily used in the Indian Ocean. They range from
60 to 90 on deck.
will be noted that these junks are rather narrow and deep. Unlike the Hainan
type of junk, these vessels are seldom used for bulk cargoes, but instead haul
refrigerators, stoves, sinks, tiles and other building materials as well as
other cargo that can be packaged. The windward ability at the expense of other
points of sailing was necessary because she also ventures into the islands at
all seasons rather than wait for the fair winds of a monsoon.
Shoal draft fishing junks range in size from 40 to 75, the more popular
ones being in the 50 to 60 length. They are flat bottom and can be
beached, but are excellent sea going vessels. Out of season, many of them do
carry coastwise freight. Like the sharpie, there are limitations on the amount
of headroom available, depending on length. In trying to compare these with
Western hulls, they are sort of a cross between a dory and a sharpie. Throwing
in their Chinese ancestry, they have the wider stern galleries. Most have a
daggerboard, but some have found it advantageous, even though it is foreign to
them, to use a centerboard since the trunk then splits the hold in half
longitudinally for better stowage of ice and fish.
