[Rhodes22-list] advice on ground for battery

[Lou Rosenberg]

>  Roger,

  Sorry about the confusion.   I will be doing separate HD cables, 
AWG#4, to the chain plates and Mast but dont really see how to 
install a ground plate where you originally said below the stb side 
near the midship point where the companionway is located?   Am I mis 
understanding you here?   My R22 has floor boards which I dont really 
want to disturb here for now.. How about fwd underneath the V berth? 
to the stb side of the keel?
  Lou
