I am considering the commissioning of a new boat and am vacillating over the choice of engines. The boats details are:
: Semi displacement
LWL: 55 feet
: 66 feet
: 38 - 42 tonnes (light- full incl engines)
My intended use is towards a cruise
speed in the 10 - 12 knots and the ability to push it home when I want around 20 kn. Long range is an important consideration as is fuel
Anyway the choices are twin:
Cat Acert C-12 (705 hp) v Cummins QSM 11 (715 hp)
Can anyone give any guidance on these.
Apart from general suitability to the task I am interested in issues such as fuel
economy, Cummins open standard Common Rail technology v Cats ACERT equivalent, reliability
, cost of ownership
, know issues, etc. Well anything of interest I guess.
For some reason I am leaning towards the cats.
The boat will be based in Australia
Thanks for your help.
