The Group boat (G-boat), Marine Alutech Watercat M8, is primary used in the Amphibious corps (Amfibiekåren, AMF) for smaller troop and cargo transportation within the platoon and company area. The boat is equipped with a water-jet for speed and to enable fast and simple debarkation at the shore without the risk of hitting anything with a propeller. It has a very low draft making it ideal for beach landings in shallow waters.
The soldiers are sitting on two saddle-type seats where they sit astride and holds on to a handle in front of them. The drew stands/sits in the aft of the boat at a steering console with a navigation table. .
New engine 2013
Dockstavarvet AB won the procurement in 2013 to modify 65 G-boats.
In the modification the existing Volvo Penta KAD42 engine was replcaed with a Steyr SE236E40 delivered by
Nordic Gensets & Motors AB. One of the requirements in the procurement was to be able to stress the engine to 100 % during 75 % of the specified run time.
That requirement made many competidors to fail as the effect norm says one out of eight hours.
The Steyr Engine has 230 hp at 4 000 rpm and weighs 340 kg. ²
5 st has been made by Marine Alutech for civilian customers between 1997-2003. The Finnish Navy has bought 1 st and an additional 22 in 2001.
