YES the boat only ever did one trip of note from Hebden Bridge to York 
in 5 years. The rest of the time it was on the Rochdale being used as a 
livaboard and not moving very much at all.
OK so there is double the power and half as many cylinders again but the 
principle of light loading still applies to all engines.
If you consider that a 5hp engine will run a 5kw genset then a 40hp boat 
engine is hardly being loaded even with a 5kw travel power attached 
running flat out which unless you are running a big aircon or heaters it 
wont be, even with a washing machine, 85% of the washing machines cycle 
is without the heaters so will be about 3-400watts.
Most use of 230v on a boat (except for charging the boats batteries if 
that is done from 230v) is well under 1500w total except for very short 
periods, so inverters and a dedicated 24v charging generator makes far 
more sense than a travel power both electrically and  environmentally.
