Question about silent running and engine noise

Canovaro · 03-15-07, 07:00 AM

Is there any documentation or knowledge available about how much noise the engine makes at let's say onethird power compared to let's say full power at silent running?

In other words:
How much difference does silent running rig make?
I hope my question is clear

IIRC you need to be at less than 2knotts to be in silent running.

Silent running is a state where the engine is turned down to 2, no reloading or repairing etc. What I mean is that the engine is not technically in silent mode but going at slow speed makes it quieter.

Thanks for your answer.
So "silent running" is not a technical engine / equipment thing, but only means slow movement and no/little noises being made in the boat?

Correct. Electric engines on 2kts and crew very quiet. No torpedo loading or repairs to be made.
