The ZWARTE ZEE commissioned in 1963, is a single-screw ocean-
going motortug with a gross tonnage of 1539 tons, built by J. K. Smit's
Scheepswerven N.V. at Kinderdijk (Holland) to class Lloyd's Register
100 A 1 Tug. Her main dimensions are:
Length o.a.
77.50 m
Length b.p.p.
68.50 m
Beam mld.
12.35 m
Depth mld.
6.90 m
Draft at C.W.L.
5.75 m
The propelling machinery, installed midships, comprises two Smit-
M.A.N. turbo-charged diesel engines, fourstroke, single acting, direct
reversible, with a combined output of 9,000 ihp. These engines drive
a single propeller shaft through Vulcan fluid couplings and reduction
gear. If quick manceuvring is desired one engine may be run ahead
while the other engine is running astern.
The reversing of the direction of rotation of the propeller may then be
attained by simply clutching either one of the engines to the gear.
The free running speed exceeds 18 knots. The tug's large bunker
capacity enables her to perform ocean towages with heavy objects
over very long distances without having to refuel en route.
Three generator sets of 240 kW each supply 220 Volt direct current,
whilst for emergency cases an additional 20 kW compressor generator
set is installed.
Adjacent to the engine room is a workshop equipped with various
machine tools: lathe, shaping machine, grinding machine, drilling
machine, welding units, as well as a welding converter which can be
used in underwater cutting or welding. The ZWARTE ZEE is equipped
with two fibreglass boats, each with a capacity of 40 persons. For the
transport of materials etc. during salvage operations, the tug carries a
workboat which is lowered by means of a hydraulic crane.

Fig. 1: Hull and Sternpost.
Fig. 1 shows the various parts to be fitted into the hull no. P125. Cut
to shape on the drawing (A). Position the keel strip no. 1 in the hull
no. P125 (see Main Drawing) and glue with contact or two-componen
cement. Place the frames nos. 2, 3 and 4 on the keel strip, with spacing
as indicated on the Main Drawing. Remember to shape the hole for the
propeller shaft no. F636 (to be glued on) in frame no. 2 and to drill a
hole for the shaft in the hull. The sternpost consists of parts 843/a and
843/b. Glue with plastic cement. Position the two edge strips 1A, plate
no. 8 and strips no. 9 as shown on the drawing.
Fig. 1a: Rudder.
The rudder is assembled using parts 845/a and 845/b, which are glued
to the rudder stock no. F476. Drill a hole in the hull, where the rudder
and rudder trunk can be attached. Use cement to fill in and seal the
area around 476 and 636 in the hull, and position no. 843/c to reinforce
the glued area.
Fig. 2: Deck and Spacers.
Fig. 2 shows the various parts to be used in the assembly of the deck
and hatches. At this point it is necessary to know the type of motor and
R/C equipment which will later be used. Make sure that the deck and
spacers are glued securely and tighly togehter. Tape can be used to
secure the ends.
Fig. 3: Bulwarks.
Glue the bulwark supports from A to D on the deck into the respective
holes. When the cement is dry, position the two reinforcements no. 75
as shown on the drawing. Next position the two parts no. 20, remember
to cut out a hole for the scupper. Position no. 21, glue with contact
cement, and hold in place with clothespins until the cement is dry.
Shape supports no. 14 from a wooden list no. 14. Place bulkhead nos.
11, 11a and 11b as shown, and on top of these position deck no. 12.
Assemble the coaming nos. 67 and 43 as shown.
Fig. 4 and 4a: Aft Deck and Towing Winch.
The assembly of the cabins, engine room and towing block can be
seen on Fig. 4 and the Main Drawing. Use white cement and tape
the parts together until dry. Fig. 4a shows the positioning of the three
trestles no. F204. Solder the vertical posts, or glue with metallic cement.
Fig. 5 and 5a: Boat Deck.
Fig. 5 illustrates the various parts belonging to the boat deck. Glue all
parts with white cement and hold with tape until dry. Compare the parts
with the Main Drawing and illustration. Position the funnel when the
cabin and deck are assembled (see Fig. 5a) and glue strip no. 62 along
the entire deck.
Fig. 6, 6a, 6b and 6c: Cabin with Bridge.
The construction of the cabin for the bridge is shown on Fig. 6 and
the following detailed drawings. Moisten parts no. 55 and 55a slightly,
join with white cement, and hold in place, eg. with pins, until dry. The
completed bridge mounted on the boat deck is shown on Fig. 6a. Figs.
6b and 6c show details of the assembly.
Fig. 7, 7a and 7b: Finish.
The various parts of the model can now be stopped, and the deck can
be varnished. Colours can be seen on the packaging, the colour chard
and the various figures, and the varnished fittings can be positioned as
shown on the Main Drawin and detailed drawings. If the model is to sail,
cover the inside of the port holes in the hull with clear plastic.
Fig. 8, 8a, 8b and 8c: Masts and Crane.
These figures show the assembly of the masts and crane as well as the
completed model. Paint the masts and crane before positioning on the
model.
