Curb Weight5,500 Pounds (2,500 Kilograms)
2500 kg loaded with 160 liters of diesel,
160 liters of water, food, etc.
Additional Features24 VAC Power supplied by 4 KVA Marine Generator or shore power;
roof lifted by 2 stage pneumatic cylinders; has a 5th wheel
hitch alloy boat trailer towed by Toyota 4.5 liter diesel
Workmate (pickup).
A quiet, fuel efficient boat for exploring inland waterways
in relative comfort and safety; with capacity to launch and
retrieve on a trailer for transporting overland from one
waterway to another; comparable to six meter caravan like
amenities in an eight meter boat.

Strong plate alloy hull; pop-up roof for low wind resistance
when towing; all around screen canopy for maximum vision,
cooling, and insect protection; 24 V lithium battery bank;
two 2 kW permanent magnet motors on propeller shafts (no
gearing); and a 4 kVa marine diesel generator.

The two electric motors propel the boat to a top speed of 10
kph, with capacity to travel slowly on battery power for 3 -
5 hrs until the generator is required to power the motors and
recharge the batteries. The generator runs at its most
efficient rpm supplying 240vac to the inverter/charger until
the batteries are fully charged. The 2,400 kilometer journey
down the Murray River from Yarrawonga to Goolwa lasted 127
days and used approximately 260 liters of diesel.
