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.
By Dr. Nikolai M. Tranulov
Manager of RTD Ltd.
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.
The type of ship is barkentina Three masts for sailing educational purposes, with maximum continuous power of main engine 340 hp, dvupaluben with sheer and curved beams with milk and kliperski trimmed cape. Its purpose is to train practitioners and kreyserski voyages. Sailing area is unlimited.
The main dimensions and other important characteristics of the vessel are as follows:
