So much for the rant about charges.....see what your new inverter capacity is and then add up what appliances you think you will use to draw from this, that should give you an idea of your new needed battery capacity and type.Sometimes when you start adding up you find the needed size for the inverter is larger than you think......Mike

I recently had a 320 Cruisers, in which I installed four TROJAN six-volt golf cart batteries, for the house, and successfully anchored or docked on islands without shore power for two weeks, with proper input from the onboard Kohler genny, and I took along a Honda 2000, since I already owned it, and it's so inexpensive to run for hours.

Needless to say, I kept the fabulous six-volts, but have not yet had a chance to review what's in the Carver - I only know there are two twelve-volt house batteries in parallel.

Interestingly, my first impression is that there seems to be less room in the Carver engine room for additional batteries, but I'll probably find a way by moving or adjusting the battery trays, if possible.

If you have room, and want to switch to six-volts, you will be most satisfied with the increase in amp hours. Four six-volts will beat two twelve-volts every day of the week. A little more expensive to set up, and you'll need some extra cables, but well worth the effort.

Here's a close up of two of my six-volts. I use the T-105.

And a link to Trojan for all the specs.

p.s. we boat The Bay annually, lurking around Beausoleil, not far from you, so perhaps we'll cross paths and can compare notes. Feel free to keep in touch over the next year, as I'll gladly share any knowledge I obtain with respect to good Mariner battery management.

So far I'm planning on 3 group 31, a separate battery for each engine, and 1 for the genny. I will upgrade the charger to a promariner 50amp 3 bank, and also install a promariner isolator 2/3 (2 alternators / 3 batteries)
We'll be moving from Krates to hindsons after the long weekend.

After Taxes wrote:Hi Fraser,

I haven't tackled the battery job yet. My beautiful Trojan six-volt batteries are in my basement on trickle charge!

My research with Carver, shows that the Mariner was factory produced with only ONE house battery, which was located beside the two engine start batteries, in the area in front of the generator. (the genny batter was factory installed directly in front of the genny)

In my boat, the previous owner had the genny battery moved to the starboard side of the genny, and a second house battery installed directly in front of the genny, where the genny battery used to be. So, it's a little tight in that space, but there are four batteries, two house and two engine starts.

With some other pressing jobs, I haven't taken the time to measure and determine how or where the six-volts would best fit.
