3. Stability and Unsinkability
Catamaran is highly stable, and the capsize is unlikely for most cases with wise control, except
intense regimes.
It is not recommended to allow the windward float to takeoff from water as the righting
moment will decrease, while the upsetting moment will be same or will increase, resulting in
catamaran rollover.
Overkeel is also possible at beam to sea sailing with wave condition close to extreme mode.
Catamaran Recovering from capsized state is possible by one person.
Catamaran remains afloat in case of any of the four sections of floats damage.
Helmsman (or in his absence, the person responsible for the catamaran safety) remains
responsible for boat stability and unsinkability during exploitation even in case of meeting the
requirements of this manual.
4. Crew
One person with Yacht Helmsman qualification is enough for catamaran steering. The
maximum amount of people onboard must not exceed 4 persons.

CATAMARAN CONSTRUCTION
Floats provide the buoyancy of catamaran. They are made from PVC fabrics and have
impermeable partitions dividing every float into two compartments. Every compartment is
equipped with a valve for filling with air. The floats are attached to the bridge with loops.
Bridge is аload-bearing unit of catamaran and takes on the loading of rigging, crew, etc. It is
made up of two compound longitudinal beams –stringers, three transverse beams –bow
beam, under-mast beam, stern beam, and diagonal cable tension braces - lower bridle.
Stringer beams consist of two parts: bow (short) and stern (long).
Trampoline is made from PVC net and serves for crew accommodation. Trampoline’s sleeves
are put on the stern and stringer beams. Trampoline is tensioned by lacing to under-mast
beam.
Cargo net is made from a nylon ribbon and intended for placing of luggage and crew. Cargo
net is put on bow and stringer beams by sleeves and tensioned by lacing to the under-mast
beam.
Centerboard unit consists of the centerboard and the centerboard box. The centerboard is used to
reduce the drift of catamaran when sailing upwind. Rubber expander holds the centerboard in
operational (vertical) position. Expander absorbs the hitting of underwater obstacles, thus
allowing avoid the serious damage of the centerboard. In moorage (horizontal) position
centerboard is raised by halyard and held with clam cleat on the under-mast joint unit.
Rudder unit consists of the rudder blade and rudder box. Rudder is used to control the catamaran.
It is mounted in the rudder box, which is attached to the rudder joint unit. Rubber expander holds
the rudder blade in operational (vertical) position. Expander absorbs the hitting of underwater
obstacles, thus allowing avoid the serious damage of the rudder blade. In moorage (horizontal)
position rudder blade is raised by halyard and held with clam cleat on the rudder tiller.
Rigging consists of the mast and sails. The mast consists of four pieces which are interconnecting.
Standing rigging includes forestay and shrouds which hold the mast in position. Tensioning of
shrouds and forestay is done by forestay's lanyard.
Running rigging includes tackle to control sails: the main-sheet, the jib-sheet, and gennaker-
sheet.

CATAMARAN ASSEMBLY
Note: Some parts of your catamaran may differ from those shown on the photos.
A catamaran is packed into three packing. Two long packing include beams of bridge, stringers,
mast, rudder and centerboard units, standing rigging, cargo net and trampoline. In the third
packing there are floats, running rigging and pump. Sails are packed in separate duffle bag, but, if
desired, could be added into one of the long packing.
1. Inflate the floats, but do not make the pressure up to working level. That in the future will
facilitate the assembly process.
2. Assemble the under-mast beam, which consists of two parts. Install the centerboard unit on it.
Fasten the under-mast beam to the floats by inserting into the loops the half-arms of the right and
left sides.
3. Setup the cable tensioners of the centerboard box.

4. Roll out the trampoline that wound on stern beam. Put the stringer’s stern part into the sleeve
of trampoline, and then into the loop on the float. Join the stern part of the stringer with the
under-mast beam.

Stern Parts of Stringers

5. Put the stern beam through the loops on the floats and join it with the stern parts of stringers.
Important: by turning the stern parts of the stringers achieve their maximum possible deep set in
the stern beam.
6. Roll out the cargo net that wound on the bow beam.

7. Insert the stringer’s bow part into the sleeve of cargo net. Join the bow part of the stringer with
the under-mast beam and stern part of stringer.
Important: by turning the bow parts of the stringers achieve their maximum possible deep set in
the stern parts of the stringers. Make sure that under-mast beam does not slip out from the stern
parts of the stringers.
8. Put the bow beam through the loops on the floats and join it with the bow parts of stringers.
Important: by turning the bow parts of the stringers achieve their maximum possible deep set in
the bow beam.

9. Roll out the diagonal cable tensioners of the centerboard box and set them up. Two long
stern cables pass under the trampoline and are attached with shackles to the lugs in the corners of
stern beam. Two short bow cables pass under the cargo net and are attached with shackles to the
lugs in the corners of bow beam.

10. Put the plate, that interconnects the diagonal tensioners, on the centerboard box finger. To do
this, stand on the edges of the plate with your feet, so that under the influence of your weight
there will be a necessary gap for installation.
11. Lay the centerboard halyard into the moor position. Put on the expander, which will lower the
centerboard into working position. Lock the centerboard in the moor position with stopper.
Note: for convenience, the expander can be put on at the end of the assembly, by topple the
catamaran on its side.

12.a. For catamarans equipped with gennaker. Install the bowsprit. It is composite and consists of
two parts. Install the short part of the bowsprit and fix it on the centerboard box.
12.b. Connect the long part of the
bowsprit with the short one and fix with a
button lock. Attach the bowsprit to the
bow beam with the strap.

13. Stretch the trampoline up. For this, first, lace up together two halves of the trampoline, and
then lace it to the under-mast beam.
14. Stretch up the cargo net. For this, lace it up to the under-mast beam.
15. Assemble the mast. For this, interconnect the four mast segments.

16. Unravel the forestay and shrouds.
Attach the forward lower shrouds to the
lugs at the left and right side of the
under-mast beam with shackles.
17. Put the jib halyard (if you have a model with the outer laying
of jib halyard) and the gennaker halyard (if your model is
equipped with a gennaker) into the outer blocks.

18. Lean the mast on the under-mast joint unit. Put the ring with forestay and shrouds on the mast
hook.
Important: make sure that the forestay is in the center, between the shrouds.
19. Raise the mast. If you have two people, then the one who
holds the mast, should lift mast’s top as much as possible
upwards. While second person should stand in front of the bow
beam and pull the forestay. If you are alone, then lean the mast
on the under-mast joint unit and walk on the catamaran from
the stern to the bow and lift the mast. When the mast is raised,
take the forestay and go to the bow beam. Make the tension of
forestay by forestay lanyard and secure lanyard with a knot.
.
Note: Beware that the mast does not fall and hurt you or others.

20. Install the rudder box on the rudder joint unit.

Gennaker-sheet Block
21. Attach the jib-sheet blocks to under-mast beam with straps.
22. For catamarans equipped with
gennaker. Attach the gennaker-sheet
block to under-mast beam with strap.

23. Hoist the jib up. For this, tie the jib halyard to the jib halyard point. When the jib is hoisted,
lock the jib halyard with the horn cleat. Tighten the jib forestay with lanyard. Forestay should sag.
A good tension of the jib forestay will allow a sharp angle when tacking. Attach the jib sheets to
the jib clew.
24. Hoist the sail (main) up. For this, tie the mainsail halyard to the mainsail halyard point. When
the mainsail is hoisted up lock the mainsail halyard with the horn cleat. While mainsail is hoisting,
fix the battens with batten tension straps. Lightly pull the luff of sail with mainsail downhaul.

25. Attach the lower block of the mainsheet to the ring of main
traveler, and the upper block - to one of the clew grommets. Choose
the grommet closer to the mast for stronger wind.
26. Fix the gennaker bag on the cargo net with the cords.
