Condor Vitesse was built by Incat Australia, Hobart, Tasmania, in 1997 for International Catamarans. She is Incat hull number 044. She is 86.6 m long and 5005 gross tons. Ruston diesels of a total of 28320 kW give a speed of 40 knots. Condor Express can carry 800 passengers and 200 cars.
Condor Express was built by Incat Australia, Hobart, Tasmania, in 1996. She is Incat hull number 042. She is 86.6 m long and 5005 gross tons. Ruston diesels of a total of 28320 kW give a speed of 40 knots. Condor Express can carry 776 passengers and 200 cars.

28320kW/(800 * 40 knots)/0.3 in kWh per km
= 1.59 kWh per km
159 - but taking 200 cars which is equivalent to the mass of an extra
3000 people!
according to

this could take 900 passengers
Two Incat 91m catamarans have broken the record for the fastest Atlantic crossing by a passenger ship. Catalonia took the Blue Riband and Hales Trophy in June 1998, with Cat-Link V sailing into record books as the third Incat craft to claim the famed accolade one month later.

on her 1,050 nautical mile delivery voyage to Florida in May 1999 she consumed just 4,780 litres of fuel. That's one gallon per nautical mile for a boat averaging 22 knots over the distance and carrying the equivalent of 30 passengers.
Gold Coast Yachts says this performance can be achieved with as many as 70 passengers aboard.
PASSENGER CATAMARAN
4780*10kWh / ( 70 * 1050 nautical miles) in kWh per km
0.35 kWh/km
35 kWh/100 pkm
Displacement (full load) 26.3 tons.
% 70 passengers with luggage means 7000 kg
That's a transport efficiency (using the vessel weight) of
% 47800 kWh / (1050 nautical miles) / 26.3 tons in kWh per (ton km)
% 0.934634626 kWh per (tonne km)
0.93 kWh per (tonne km).
cf gravity is 2.7kWh per tkm.
So the catamaran is effectively going up a slope of $1/3$.
Typical engine efficiency: 240g per kWh.
% assuming density 0.8 Assuming 45 MJ per kg,
% 0.24*45 MJ in kWh
% 0.24*45/3.6
% Exactly 1/3 !!
