Placing battery

[Jari Hjerppe]

Soon it's time to start installing all necessary equipment into the Humber. What would be the best place for the battery. There is a battery hatch in the helm console just below the surface where the compass will be installed. I'm worried that if the battery is close to the compass it will affect compass' accuracy?? Is there any common or "normal" place in a small rib that battery is installed in?

thanks

Jari

I don`t know what you call it in english but after you have installed the battery into console you by a calibration plate that you put under the compass, it will take away all the magnetic field around the compass.
Offcourse you have to calibrate the compass by driving a fixed course.
We use it in our boats here in Swe even if battery is sitting somewhere else.
There is always magnetic fileds from electronics etc.
The plate does`nt cost very much just a couple of €uros.
Go to Silva in Finland they have a great one that we are using.
