A somewhat smaller harbor tug, primarily operating in Polish ports. The vessel was originally used by the navy, but has been modified several times for private use and therefore exists in many versions.

Self-built from a free plan of the Emilka.
Scale 1/13
1.5mm plywood, polyester (glass cloth), and plastic.
Acrylic paint with a 2K varnish.

Length = 86 cm
Width = 35 cm
Draft = 10 cm
Weight = 15 kg
Motor = 900 High Torque 12 volt
Battery = 12 volt lead acid 15 Ah
Battery = 4-blade brass propeller (75 mm) in the propeller tunnel
Ship siren and medium-power diesel sound system (both 12 volt) on board with two (8 ohm) speakers

The intention was to build a ship that could withstand somewhat rougher weather, while still remaining somewhat manageable.
