Bob, on Pegasus I have a 4d (house 1) under the port q-berth, a pair of
6volts under the companion way (house 2) and a pair of group 24 for starting
and windlass on the shelf to port of the engine. This keeps all heavy battery
cables (except windlass) in short runs, lessens the voltage
A couple good points were made here. At the present moment my second (44-lb)
anchor and rode are not on the bow--once I add this, it will help with weight
distribution.
The other benefit of moving batteries around would be space gains in the
starboard cockpit locker where I now have two batter
How about more water tanks instead? Cruisers can't have to much water.

I think ABYC is a little to conservative on this issue if that is their stance.

When you add the windlass you'll have the battery!

If it will be very rare to ever need a v-berth house battery for engine
starting, how about, if the need were to arise, disconnect one of the
v-berth batteries, take it aft, and use some jumper cables to get the
engine started.

Technically vapors are an issue. All battery types - wet/sealed/gel/AGM -
are subject to ABYC venting guidelines. There are some solutions - venting
the battery enclosure or having vented caps for wet cell directed overboard
somehow.

I DO use AGMs--so, vapors are not an issue. I have some space just forward of
the mast under the settee but close to the boat's centerline that might work
for battery storage--I have to check out the dimensions but this would remove

Bob — I would consider sizing the wiring aft from the forward batteries to
allow at least 100 amps, with a maximum 10% voltage drop. This would require
at least 4AWG cabling from under the v-berth to the electrical panel aft;
better would be 2AWG, which would allow you to pull 30 amps with a 3%
Bob,
as you said, the current from the house batteries should never be high, so the
wires should not be an issue. However, if you calculate your load at 30 A and
select appropriate gauge of the wire (for distance), make sure that you install
an appropriate fuse (probably not larger than 50 A) (
