Nothing wrong with inward turning props if you know how to use them

Yes
True!
I drove another Lurssen with inward turning CPPs. But that’s another story!!

One of my favorite little tugs was an oddball that had inward turning props as well, and it surprised me how many previous drivers didn’t realize it. I guess not many other guys go into the engine room?! She didn’t seem to twist very well, but would walk better than others of her size and horsepower.
I don’t know if the comments regarding inward turning screws had twin rudders. My experience was with a single centre line rudder and it was a dog.
In all fairness my experience was with twin rudders
Inward turning CPP or outward turning fixed pitch are best for manoeuvring obviously combined with twin rudders.
Really ![]()
the handover notes regarding the vessel in question with its single rudder were:
See what ever way it wants to go and help it hoping for a happy ending.
Well yes it is astonishing that many ship handlers do not know that including those who work on twin screw ships.![]()
The number of outwards turning CPP ships there are also demonstrates that some naval architects and engineers do not know that too….astonishing ![]()
I drove one of those for a single trip one time too. It was a total dog. Had to carry a scary amount of headway in order to get anything out of the rudder. Anything below 2-3 knots, might as well not even use it.
Yes KaMeWa
(as shown on pitch ind.)
You need to get the fenders out when a narrow lurrsen is backing in beside you.
Most are huge beam but Izanamai was well known, had to back in fast…
A lot of the old graham utility boats (g-boats) had inboard turning wheels. Boats didn’t pivot the best but they walked sideways like a champ.
Yes they did. And they were great. I held upwind under the crane for crew change in 25 kt winds and 12 ft seas with the Ray G, one of the 96 footers equipped with 12-71s. It was fun watching the other captain immediately bailout as I was going up in the basket.
Plenty of quad screws in the past also. If the outboard wheels were NOT inboard turning, you knew that you were in for a tougher time.
I ran a couple of quads also. I just remember if the outboard mains were outboard turning you used the opposite inboard engine for the walk. Long time ago, my memory is fuzzy about it.
