The Hybrid
or Gulf - Cajun
Towboat!
Gulf Shipyards have created for many
years, an all purpose = Vessel .... Well Almost! Because it borrows
much from the tugboat - itself, but also uses a typical towboat hull
designs! Keep In Mind Here, Stylish Lines don't make profits, but its
easier to look at with a little - Sex Appeal. So the Hybrid or as
their usually called = Cajun Towboats, have their advantages and place.
Because "Cajun Towboats" certainly have a few extra curves - In
Places, where other boats don't even have = PLACES! .....
But in comparison to "Upper River
- Designs, Gulf Shipyards that build "Hybrids" of all towboats, which is
often called a Cajun Boat because they are unique to southern gulf
regions and their area's - builders. Seemingly an attempt to create a
vessel with both "Deep & Shallow" Water Characteristics, married
together with tugboat traits like - "Bulwarks", which are those "Solid
Steel" side-railings, extended completely around the main decks on a
Tug. Naturally that makes the Cajun - look a lot like a Tug, to the
average person that doesn't know - the differences in work boats. And
when you add the use of "Water Tight" Doors = called Hatches ..... These
vessels are often mistakenly called - River Tugs. Being mainly why
there is and has been so-much confusion today, about "Which Is Which" in
Workboat Class. and what these boats are supposed to be called?
Having both -
Blue Water
& Brown Water = Characteristics, allows Cajun boats to
operate within unprotected ocean waters ( during calm periods = Or Light
Sea Condition's ), as well as inland river traitss too. Makes these
boats most suitable for work on the Gulf - Inter Coastal Canal ways.
That's a man made dug-out river channel, which extends along our
southern coastline, widely used by these types of towboats. Actually
its just - off shore and somewhat protected by barrier islands and
extends along our shore lines from Florida's - west coast, down to
Brownsville Texas. And then also extends further up Florida's -
Eastern Coastline, to almost "New York City" before it ends.
Gulf shipbuilders do
things differently from Upper River Shipyards, which sort-of creates the
argument about whose boats are better designed? Today a used "Cajun
Towboat" still brings a much lower price, when compared to the same size
& type of vessel, built by an upper river shipyard. "Why - You
Ask?"...... Because of several reasons actually, which involve the way
many - Cajun boats were designed or how they're equipped. For
example, take their = "Flanking Rudders", which are often arranged on
the hull, in odd ways that reduces their abilities to steer in
Reverse. Many used Cajun Boat - buyers, dry-dock and redo the
steering, before they do anything else to these used boats, because they
handle poorly in reverse. Gulf shipbuilders have dor sometime, felt
towboats only need 2 Flanking Rudders ), while Upper Shipyards always
installed = 4, on twin screw vessels of the same size. That's because
upper river shipyards - understood fast currents and their effects on
these boats, when working in very tightly cramped spaces. But it took
a while before such ideas - spread and became common place. Also
upper shipyards install flanking rudders, so they're spread apart at the
forward ends, to actually scoop water into the props for better thrust.
Mounted just inside of the
diameters of the Propellers - Widths, is a common Upper River Trait.
While some lower Gulf Shipyards, seemed to consider that a waste of
time, which they finally had to follow - As everyone was converting
their designs to use this trait. So often, you find older Cajun boats
with flanking rudder problems - Or did, until buyer's started demanding
changes in these area's. But some boat designers - didn't or wouldn't
change, so they lost out, to those willing to see the light. And when
a boat can last over 50+ years in service, its bound to be sold several
times and go through many refits, A lot of changes under different
owners - over the years and you begin to see how such things - effect
the value of boats. When a major refit is so expensive, buyers look
at used boats - first, for the least need of rebuilding, to drastically
save money in buying & rebuilding. And for early Cajun Boats, it
simply became to expensive to rebuild them and many were scrapped.
Operational service time, on a vessel is critical to its profitablity
and that forced the changes to more modern boat designs. So in some
cases, builders were simply stuborn and refused to change, so they were
bought out or closed So this all makes a lot of sense, when you
realize its like saying - Your Boat ( Or Its Designer & Builders -
Idea's ), "Ain't Worth A Hoot!" ....... When the boat doesn't get resold
and change hands with any amount of service time on it. Means there's
more to profitability, then just cost effective designs, and a builder's
eego at stake, because the longer yer boat - Runs, the more others want
yer designs!

Weird Look'un
-
Towboats"
The "Retractable Helm" - or often called a
"Jack-Up", is also often called a = Jack'er too. Built as Tenders,
Trip boats, Line Haulers and also a few super large - Long Haulers.
these odd looking boats are rated from 500 to 5,000+ horsepower.
Built as Single & Twin Screws usually, but there are also a few "Triple
Screws too". And they can show characteristics of either - Upper or
Lower River styles, in shipyard designs, As a "Cajun Jacker", you'll
naturally find "Bulwarks" - or a solid railing around their main decks,
which is a common give away in whom built it. Those built by Upper
Shipyards - won't have these traits, so there can be a vast difference
in their looks and shapes. Looking more typical of all upper designed
boats, they all have the hydraulic - raised helm. And of course, some
builders specialize in these types of vessels, built in all classed
sizes, as well as for special jobs that require their unique
capabilities = Of Ducking Under - Things, Or Going where other towboats
- CAN'T!

Affectionately
called - THE UGLIEST BOATS - AFLOAT!
YEP! ...
There are truly some weird look'un
boats = Out there! Some as they humbly put things in
Towboat Slang = "Just Pure = BUTT UGLY!" ......... However
looks - Sure Don't Make a Profit in type of
Workboat, as any "River- Rat" will also quickly point out. But
these 2 - examples ( Above ) show how some Jack-ups, help put extra = Ug
.... in Ugly. And while Beauty may only be "Skin Deep" in this case,
it sure appears ugly went plum to the Bone on these vessels. Or seems
to have, until you look closely at what these boats are especially
designed to do, and just how easily - They Do-it. Then that Ugly -
Odd looking design they're well known for, suddenly takes on a whole
new kind of Beauty = All Its Own!
Note both of the above
vessels carry the same features ( A "Retractable Helm" ), which is the
main reason for their - odd and often rather ugly looks. Called
"JACK-UP's" or Jack'ers, the helm is mounted atop Hydraulic Hoists that
allows the pilot to "Raise or Lower" the helm, whenever needed. This
allows the vessel to - duck down low, when going under a low bridge that
normally would restrict any other taller vessel. So Getting under
things - so to speak, is exactly what these boats were designed
for, and their real great to have around in High Water Times Too. When
a normal boat can't get under a bridge, these boats step-in and take
barges further upriver and continue the trip, where others - can't
go. So they play a very special role in river barge transportation of
materials = past the difficult points. (
Note the left photo - Above ), shows the
retractable - Helm - In its "Down Position".
While the photo on the right
- shows the Helm - Raised, to its highest
points. Demonstrating how these boats - look, in either case, some
can raise their helms, well over 30' above the "Main Deck" to give
pilots a clearer view over barges and their cargo. Jacker's are
popular on all rivers, but mostly used on the Illinois, lower Gulf
regions and where a lot of rivers merge into the Mississippi - which
have low bridges or lower than normal obstructions to navigate!
Above
Special Photo - Details
Note the Right Photo - above,
also shows a vessel equipped with a pair of
"Stern Mounted" - PUSH KNEE'S.
Indicating the boat is also used, as a "Bow Boat" as its called, in some
of its work.. That means the boat can be used to steer - the head or
forward lead - barges, of a large tow. By lashing - its Stern, to the
head of the tow, or leading barges, in order to steer the forward part
of the barges. While another towboat pushes - the stern, in a
typical fashion. This is often done when barges haul something that
restricts a pilots clear view, and requires a second boat to assist the
tow to its destination. And its not uncommon to see = two vessels
handling what usually looks like a - One Boat Operation, which has some
sort of difficulties, that may not be obvious to observers, but its
always interesting to watch!
