Hannu,
That's really useful information...Thank you.
Only about 60 hp ICE are required to push a 70 metric tons displecement
steel yacht, of 25 m length, with authority.
The 100 hp+ engine was vastly overpowered (old engine from a train,
heavy and large displacement).
Approx 100-150 hp was used on early commercial ships, in the 200-300
tons size, early 1900.
A 60 metric tons nordhavn only uses about 30 kW of power, ice, at 90% of
hull speed.
A typical avg from several owners over thousands of miles made good.
Likely, 15 kW of electric engine is sufficient, imho.
