That's about the slickest looking tug/trawlers I've seen - but new to me. We are sailors. Do they have an owner's forum? You might look.
Looks like low CG which is good for manerlyness. Round flat stern may pitch
but deep cutwater looks favorable.
For what its worth, our 36 ton X 58 foot Camper Nicholson ketch
has a 24 inch 3-blade prop. 2:1 reduction with Westerbeke
115 HP straight 6. The prop is Hundested variable pitch
. Pitch control is manual crank on deck
. This allows us to adjust the prop pitch to sea and wind
conditions. This saves a lot of fuel
and gives us huge thrust at low boat speed. This is a valuable option if available. A high end variation of this automatically adjusts the pitch according to a progis ram module based on rpm
, speed, exhaust
temp etc. (magic) A fringe benefit is that you can pitch the blades to stall a run-away.
