Real world anchor winch cable size

[RupertW]

I don’t know, hence the question. I don’t think so, but i do wonder why, when according to the theory ( as I understand it) it should be a problem. It bothers me when trying to learn stuff that what I’m told doesn’t relate to whats on the ground.

According to what theory? A temporary voltage dip under load may not be ideal and might suggest the battery bank is undersized if it’s sustained but no reason why a winch won’t work perfectly at that voltage.

80a for 24v,150a for 12v is what the specs say here , just going from this.

We have Lofrans Kobra 1000w windlass on (IIRC) 35mm cable run of about 11m one way. Breaker is 100 amp and doesn't trip.

Manual here, see section 4 - Lofrans windlasses and Installation manuals

The only thing I have found affected by temp voltage dip on start is the ebispacher which supposedly takes 39A briefly on start. However if that drops voltage at the heater to 10.5v or below, refuses to try and turn on.

So what if your anchor winch is sluggish to start, so are many of us?

The Eber should be on the domestic batteries and the windlass on the engine battery, problem solved.

If you have old 1 switch 2 like our old boat there is no engine battery. Current boat has engine bat (feeds winch) plus 2 aux but not all have same battery system

You said "The only thing I have found affected by temp voltage dip on start is the ebispacher" so i was addressing you, not "everyone"
