It is intended for movement on water of one adult person with a cargo. It is a trimaran consisting of a
central hull with emergency buoyancy compartments and two hermetic outrigger floats. Sailing
armament according to the scheme aft mast rig. The mast is wooden glued (spur 80mm, top 70 mm), or
duralumin (D 16t 60mm × 3 mm wall). The mast steppe is located in the rear part of the hull, the mast
itself is inclined in the diametral plane forward at an angle of 12 degrees, unfolded by a stalk, a backstay
and two guys.
A sail of 19 square meters is a Genoese stile that is fastened with raks-carbines to the staff and lifted
by a halyard (6 mm) through an external block on the top mast. For ease of management, the sliding
block of the sheet (8 mm) is attached to a special chase, which allows you to manage one sheet instead
of two. To facilitate the work with the sail, a block is attached to the sail corner at the sail corner,
allowing to hold the tackle in two or more lobes. For safety reasons, this unit should be strong, but not heavy.
The running end of the sheet is taken out to the center of the hull in front of the tiller, which
allows the helmsman to operate the traditional grip.
The corrugation system consists of two eyelets at the front and rear sail - sail and riff-seasons on the
line between them. The front grommet is pulled to the stocking-rod. The block of the sheet is
transferred to the upper eyelet on the back lining. The free flesh of the sail is tied with riff-seasons.
To compensate for the humbug, it is possible to install a narrow stabilizing sail between the mast and
the backstay, which operates on the principle of a staysail machine with a lath on the lower lining.
The steering device is a rack structure in the pantograph type. In order not to increase the draft, the
stylus pen is extended in the longitudinal plane, to facilitate the effort, the steering wheel is semi-
balanced. The maximum angle of rotation of the pen is 60 °. The tiller is shortened for the convenience
of the skipper. If desired, the extension of the tiller can be installed.
The free space in the body in the nose from the carrying truss is used as a cargo compartment and
can be closed from splashes by a special raincoat made of waterproof fabric. The trimaran also comes
with a short paddle - a rowing.
