A sailing vessel Varna 

Sailing vessels have always attracted attention with her ??exquisite appearance and beautiful views of sailing, sailing with full sails set, is really exciting. They remind us of the turbulent and glorious years of the great sea voyages of discovery of new worlds, nostalgic during "iron" sailors. Shipbuilders for the design and construction of naval ship has always been prestigious and demanding task. In a sense, the realization of a project of sailing ship could be seen as a peak in the work of a professional-yard.

During the period 2003 - 2005, the company RTD LTD made ??complete design of Three masts sailing ship, a replica of the existing barkentina BMF "Kaliakra". The ship was designed in accordance with the requirements of the Bulgarian Register of Shipping in "Rules for Classification and Sonstruction. I-Ship Technology. Seagoing Ship" 2003 and will be assigned to class housing BR 100A5 Training Sailing Yacht and mechanical equipment BR MC Yacht, and certificate under the Code for Safety for Special Purpose Ship. The project meets the requirements of BRS, the Maritime Administration, and all international and national conventions and rules applicable to the case.
Developed technical and business project is consistent with the Bulgarian Register of Shipping.

(With bowsprit) L = 54,40 m gab
Maximum length L max = 44,90 m
Length
between perpendiculars Lbp = 37,00 m
Width B = 8,20 m
Depth D = 5,10 m
Draught
project - from OL (design) d = 3,20 m
Draught
maximum of Kiel (design) d k = 3,93 m
Displacement at d = 3,20 m? = 392,00 m 3
Crew 9 / 15 people
Practitioners 25 / 50 people
Area fans of ~ 1000 m 2
Fuel ~ 30 m 3
Fresh water ~ 30 m 3
Autonomy in fuel
fresh water supplies and 20 days.
Resistance vessel design fully meets the requirements of Rules of BRS assigned to his class. It is envisaged that the deployment of solid ballast in the keel. Nepotopimostta is provided by dividing the hull watertight compartment 5. Nepotopimostta emergency and stability for its assigned class are provided in the warming of any compartment in accordance with the requirements and recommendations of SOLAS and the Code for Safety for Special Purpose Ship.
The hull is steel, with kragloskuli obvodi. The dimensions of the structural elements are defined in accordance with the rules of BRS, "Rules for Classification and Sonstruction. I-Ship Technology. Part1 Seagoing" Ship-2003. The distance between the cross rib is 500 mm along the entire length of the ship. Hull with a transverse system of sets and the structure is fully welded. The material for the construction of the hull and deckhouses Shipbuilding is plain carbon steel with yield Ren = 235 N / mm 2, tel. And, under the right: "Part 1 - Metallic Materials" 2003.

Service anchors in the nose is provided an electric combination "anchor-mooring" chain windlass with two stars and traction force 3500 kg. (Type DZC 3302). To keep the chain lowered anchors and anchors to secure the situation in the camp are two stopper with a cloak. For keeping the chain pipes hull penetrators are provided to the board and the chain box. Box chain with volume 1,5 m 3 and thereto are provided devices for quick detachment of the circuit.
