class of vessel,
ranging from 18' to just over 50' lengths and designed for small specialized jobs.
Note - Size of vessel, Doesn't indicate Horsepower = in any class, whether Blue
or Brown water Types of workboat. Built as Single & Twin- Screw
version, where utility boats can even be a small Jon-
boat with an outboard motors, equipped with - Push Knee's to qualify as a Utility
Class = Towboat. Many of these small boats are used as Fleet Tenders, or Crew
Boats and for Vessel & Barge Inspections, or
as Dredge Tenders. And as Grocery Boats, meaning just what it sounds
like, a vessel used to deliver groceries to larger vessels.
Doing this, while the larger vessel is in route, where it supplies - Crew Changes,
Groceries & Parts to the larger boat, as its passing the operational
area of the smaller vessel. Some companies also have mechanic's - on
duty, whom use these small boats to stand by, in order to do quick
repairs, or assist major repairs on boats. NOTE ....

Truck-able
Towboats
( Utility Class ), one of the oddest looking of all
small designs. Because its designed to be taken apart and re-assembled
- with a small crane, light enough to be truck & trailer transported to job sites, thus its
Truck able - term name meaning. Usually used for pushing a small
barges, called FLOATS. Note the small size
of the helm on the boat, in the above photos. Looking like a
tiny closet with windows, barely with enough room for the
pilot. So Small - You feel like stepping Outside- Just to change your
mind! And
this vessel is just - 26' feet long and a little over 14' wide and has twin engines.
Its draft would be a maximum of about 5' and carry about a 4' waterline draft
and work easily in small creeks.` Its builder located in
Florida, offer hulls - like this, up to 60' in overall lengths. ( Photo by Jan F.

Tender's
Or Tender Boats
Also
Called - HARBOR BOATS
Ranging from 28' to over 60' in
overall lengths. Horse power can be a few hundred to over 1,000 horse, built as
Single, Twin & Triple Screw versions. The term- Tender, means the vessel works
locally around Harbors and Barge fleets, or assists another vessel, called its
Mother. For example, this could be a Dredge having several Tenders in its own fleet
for helping it. You may also hear them called - Helper Boats, since tenders work
around "Locks & Dams" to assist large tows to safely enter and exit
locks. Widely used in many duties, these boats are not equipped with
Crews Quarters or Galley's. This is why the tender is commonly called a
"Dinner or Lunch Bucket" boat, meaning their crews work shifts, bringing their
own meals in Lunch buckets, thus its term meaning. Note - boats that are
equipped with crew accommodations, can also be used as Tenders too!

The M/V " John J. D." at
South point Ohio,
is a twin screw with 1,000 horsepower. Note the boat has a - Stilt Mounted Helm
..... this boat is also a "Cajun Built" design and sometimes called a
Cajun - Tender. Tender - is a term that means it has - No Crews Quarters or Galley
and the vessel is used locally around harbors. In this case,
the John J. D. operates out of South Point Ohio across from Ashland KY.
and the
Big Sandy River. Worked in shifts, her crew
- carry
their own meals aboard, thus being the reason these boats are often called "Dinner
Buckets or Lunch Bucket - Boats"! ( Photo by Joe E. Brown )

The M/V "E. W. Thompson"
has a "Skyscraper Helm" design, she is also called
a "Dinner Bucket" or Tender class vessel.
Having no - crew quarters or galley, used locally as a fleet
boat. Operating out of
South point Ohio, across from Catlettsburg Ky., you will note the "Fleet
Deck" attached to her tow knee's. This is a typical addition to
small boats. You may also have noticed - her exhaust stacks,
which go straight out, over the stern on the lower structures. This isn't all that
unusual for these boats, which have limited space to put things. The
"Fleet Deck" is built with steel - "Grated Decking", so the pilot can
see down through-it to the main deck, or so called "Head Deck" below. ( Photo

Trip-boats
The smallest, but Still fully equipped
vessels, meaning they have Crew
& Galley - Quarters for operations away from their home ports, for long
periods. A multi purpose vessel, still small
enough to be worked - locally, yet big enough to make short- Trips with
small tows. Thus its terms meaning = Trip Boat, ranging from 45' to
about 110' hull lengths. Built as Single, Twin and
sometimes Triple Screw versions, rated between 450 horse, to well over 1800+ horsepower
= in larger vessels. When used locally like a Tender or Harbor Boat,
its usually crewed by only a couple of deck hands and the Pilot for local
operations.

The M/V Sir-Ene
- a Twin screw of 800 horse, awaiting work at its dock. Note its rather tall
structures for such a small - trip-boat. This vessel measures 54' x 24' x 7' drafts,
being very stable by design, owned by Canton Marine Towing Company. All their
boats have names which begin with "SIR", a most unique way of naming vessels -
well known as a trusted company on the upper Miss River! ( Photo by Wm. Zumwalt )

The
M/V Polly- Jo A twin screw - Hybrid or "Cajun- Built"
Trip-boat of 750
horsepower. Note its Bulwarks- solid railings around part of its - main deck, its
been partly removed. Used on the Upper Mississippi at Clarksville Mo. as a
lock - Helper Boat. Not really needing its Bulwarks, her owners removed part of
them, when rebuilding this boat, from a small Tugboat, into a
Towboat! It does have a typical V- shaped bow, like a tug, under
its extended "Head Deck" on the Bow. but the hull turns into a flat
bottomed design further back, in an extensive rebuilding. "NOTE - A
towboat can operate over 50 years in service, never staying the same, constantly upgraded
to meet Coast guard regulations or any owner requirements. ( Photo by Wm.
