We have two Soviet ocean going rescue tugs here. The “Bars” and “Jahuar” . Yeah as you guessed, their names mean “Leopard” and “Jaguar” . The sister tugboats were built in 1978 in Leningrad.
They have high speed and maneuverability. They have so many rescue equipment on board including diving gear and decompression chamber. This feature also give them exploration vessel facility. But mainly it is for patching, welding or inspecting underwater. There are pumps capable of pumping 3500 cubic meters of water in an hour.
The stern bitt can withstand 300 tons and the drum 60 tons. The ships are also equipped with fire fighting gear.
Can not find so much info about them but they seem to have name changes. They may even be scrapped already…
The plan set are high quality tiff images. Scale model ship plans are very clear and easy to read. There could be more details but still enough to build a model ship.
