Fast Aluminium Workboat

Fast workboat's primary task is maintenance of maritime signalling devices and objects, such as buoys and lighthouses, transportation of lighthouse's crew  and cargo supply. Open working deck area at stern is equipped with electro-hydraulic crane. Wheelhouse and accomodation spaces are air-conditioned.

Main characteristics:

Length, overall                               14,45 m                                           

Length, hull without platforms     13,10 m                                           

Breadth, max. without fenders       4,64 m                                           

Draught                                              1,15 m

Fast workboat is built according to rules of Croatian Register of Shipping for boats for commercial purposes. It is made of sea resistant aluminium alloy (AlMg4,5Mn), longitudinally framed, welded construction. Furthermore, damaged stability requirements are satisfied.

Two four-strokes diesel engines, turbocharged, electrically started, mechanicaly regulated revolution, maximal engine brake power 2 x 275 kW, enable service speed of 23 knots.

V-type gearboxes are reversible. Propulsion plant is remotely controlled from wheelhouse control console. Electrical power is provided from batteries (24 V DC) and from diesel generator (220 V, 50 Hz, 9 kW).

Boat is equipped with VHF radio telephone for external communication. Navigation system consists of: radar, GPS, magnetic compass, echo sounder and speed log. Accomodation is provided for 3 crew members and 9 passengers. In addition, there are 4 cabin berths and 4 auxiliary berths.

Maximal stern working deck area load is 3 t. Electro-hydraulic crane, of knuckle type, is mounted at stern deck, portside. Maximal crane load is 1,5 tm.Fuel tanks capacity enables action radius of 400 nautic miles, at 23 knots speed. Stores enable 7 days autonomy.

This fast workboat is first craft built (from development program of building fast craft at our shipyard). Design was particularly carefully developed, because of specific purpose of workboat and high technical design requirements regarding speed, safety, seaworthiness and comfort, load carrying capacity and action radius. Finally, it resulted in optimal fast workboat design.

At the beginning of fast wokboat design development, the idea was to use it as a basis for various design variants, depending of boat's task. Without changing basic parameters of boat's design, and only changing above water parts, various variants are obtained, such as:

  • Fast passenger boat
  • Ambulance boat
  • Oil spill control boat
  • Luxury boat
  • Patrol boat, etc.
