4. BOAT DESIGN
In the base plane projection the Boat is of U-shaped configuration (Fig.1). The body of the Boat consists of inflatable sides (balloons)
interconnected by means of a bottom part and pasted in between transom sides. The balloon is separated by means of inner elastic
partitions into five independent compartments of a similar volume, each being provided with a fill valve.
Pasted onto Boat sides are a lifeline stanchions, side towing knots, attachment points for suspension of the Boat on hooks, thwart fixing
brackets and inwale. The bow towing knot is attached at the joint of the balloon and the bottom parts.
In the central plane projection the Boat has an elevated forebody (an average elevation angle is 12 degrees).
In order to improve the seagoing ability, the Boat is furnished with a inflatable keel which imparts deadrise to the bottom (20 degrees
in the middle section). To improve stability of the Boat, the line of connection of the bottom to the sides is located above the lower point
of the side diameter.
The pasted-in transom possesses an adequate strength for an outboard engine of marine modification to be attached. Provided on
the transom are lacing eyes for towing arrangement. The transom design provides a special place for outboard engine mounting and two
water discharge valves.
The Boat is furnished with a separable rigid boarding which serves to enhance the strength of the Boat.
Provided for Boat lifting and lowering are knots. The knots (attachment points) are pasted onto the sides of the Boat.
The Boat is furnished with paddles intended for the use in case of engine failure, to maintain the windward position of the Boat and
when mooring. The paddles are fixed on the sides of the Boat beneath the thwart.
Fixed with a sag to the sides along the entire perimeter of the Boat is lifeline intended to maintain men afloat and facilitate their climbing
into the Boat from water.
Provided on each side of the Boat are two carrying handles.
The elastic inwale serves to protect the sides against wearing out by abrasion and striking against floating objects.
The rigid seat (thwart) is fixed to elastic brackets arranged on the internal side of the balloon along the sides of the Boat.
All the above-mentioned design components of the Boat are shown in Fig.1.

5. DESIGN AND OPERATION OF BOAT COMPONENTS AND ASSEMBLIES
5.1. ENGINE UNIT
The design of the Boat provides accommodation of an outboard engine with an elongated deadwood (with the transom height being 510 mm). The engine
is fixed on the transom in a place specially provided for the purpose.
The fuel tank is arranged in a space specially provided on the boarding close to the transom. The tank is attached to the boarding by means of clamps.
5.2. RIGID BOARDING
The rigid boarding comprises the following components (see Fig.2):
– five boarding segments 1-5;
– four removable stops 6;
– two lateral beams (coverages) 7.
The lateral beams 7 serve to protect the boarding segments against relative misalignment when the crew members move across the boarding.
The upper surface of the boarding segments has a special non-slip coating.

5.3. VALVES
The Boat design provides for two types of valves described below.
5.3.1.Inflation/deflation valve.
The inflation/deflation valve is installed in each compartment of the balloon and consists of (fig.3):
- housing 1,
- cup 2 with strap 3,
- washer with gasket 4,
- nut 5,
- spindle 6 with spring 7 and cup diaphragm 8.
Before inflation of compartment it’s necessary to set all valves in operating condition. In order to switch
valve to operating condition, just press spindle 6 with your finger and turn it clockwise until it is fixed.
In order to deflate the compartment, just press spindle 6 with your finger and turn it counterclockwise
to switch the valve in position “OPEN”.
5.3.2. One way drain valve.
Provided on the Boat transom are two valves intended for the following:
- partial drainage of the Boat (down to the water-line level) being stationary or moving under
displacement conditions.
- complete drainage (to 95%) of the Boat moving under gliding conditions.
The one way drain valve (fig.4) consists of:
- body 1;
- nut 2;
- cup 3 with holding cord 6;
- petal 4;
- seal ring 5.

5.4. SUSPENSION OF BOAT ON HOOKS
The arrangement of suspension of Boat HD410 and HD460 is
identical. Provided with the purpose of Boat suspension are six
suspension rings (three rings on each side, Fig.5).
If necessary, the Boat may be fixed by means of eight hooks: six
hooks - to the rings and two hooks - to the transom lacing eyes.

6. ASSEMBLY PROCEDURE
In order to set the Boat in the running order, perform the
following operations:
6.1.Arrange the Boat on an even surface.
6.2.Set all valves in the operation condition (look before).
6.3.Lay out the inflatable keel with the valve facing upwards and
insert it into the pockets provided on the bottom. If your boat has
the keel being pasted to the bottom you will have to straighten the
keel along the bottom axis so that the keel valve may be faced
upwards.

2359.01 HD Series
Assemble the boarding according to the following procedure:
6.4.Insert the boarding segment No.5 in the boat between the
stops provided on the transom (Fig.7). The segment number is
applied on the section upper surface in its left lower corner.
Attention! Assemble the boarding so that the non-slip coating of
the sections may be faced upwards. Handle the non-slip coating
with care to avoid traumas.
6.5.Set the removable stops in the cut-outs provided on the
segments.
6.6.Set segments No.1 and No.2 closely to each other so that
segment No.1 could be pushed as far as possible to the space
beneath the bow part of the balloon and edges of both segments
could fall within the fold of the balloon and bottom connecting tape.
6.7.Set segments No.3 and No.4 as shown in the figure 8.
Thereat, check to ensure that the segment edges fall between the
planes of the removable stops. Make sure that the edges of the
remaining segments fall within the folding line of the balloon and
bottom connecting tape. If necessary, take hold of the lifeline to
adjust the balloon position.
6.8.Apply the force to the segments No.3 and No.4 connecting
zone from top to bottom as shown in the figure 9 and place the
boarding in its proper position. Thereat, make sure that the
segment edges stay within the removable stops. In order to
facilitate this process, have an assistant to pull the transom to the
boat stern part simultaneously with applying pressure to the joint
of segments No.3 an No.4.

6.9.Set the lateral beams in the cut-outs provided on segments
No.5, No.4, No.3 (Fig.10). To do it, place the beam in the boat
from one side in opposition to the cut-outs, hook the boarding
edge with the beam from below and make a pushing motion from
top to bottom and forward. Thereat, your may hold up the floor
edge from below through the bottom.
Check to ensure that the beams do not "catch" the balloon. The
segment edges should enter the beam cut-outs tightly.
6.10.Make sure again that the edges of the segments and beams fall
within the folding line of the balloon and bottom connecting tape.
6.11.Check to ensure that the rigid boarding was assembled
correctly: the segments should be arranged closely to each other
without misalignment in the increasing order of the numbers from
the bow to the aft of the boat. The keel valve should fall within
the centre of the hole of segment No.2 (Fig.11). If the keel
valve is outside the centre of the hole of segment No.2 adjust the
keel position by taking hold of the valve flange and raising the
boat bow by the lifeline. Reset the valve.
6.12.Set the rigid seat as shown in the figure 12.
To do it, insert the fixing devices arranged on the lower surface of
the wooden seats into the holes of the brackets pasted onto the
balloon. Turn and fix lugs of the fixing devices till they clicked as
shown in the figure.
6.13.Fill the balloon compartments with air using the pump from the
complete set. First fill the aft compartments, then medium compart-
ments and, finally, bow compartment. Thereat, do not bring the
pressure up to its operating value.
6.14.After all the compartments are filled check to ensure that the
boarding is arranged correctly inside the Boat.
If necessary, set the boarding as required by applying a force to the
edges of the boarding segments.

6.15.Bring the pressure in the compartments up to the operating
value (0.15 kgf/cm2). Afterwards, close reliably the inlet holes of
the valves.
6.16.Fill the inflatable keel with air up to the rated pressure value.
6.17.Assemble the oars by entering the removable parts with
blades into the locks until the click. Make use of the holes provided
in the oar handles to set the oars into the rowlocks with the blades
being faced to the aft. Secure the oars in the holders.
6.18.Close the water discharge valve holes with plugs.
6.19.Mount the outboard engine on the transom.
6.20.Arrange the fuel tank in a special place on the boarding. The tank
shall tightly seat between the restraining planks. Secure the tank with
belts.
