OK, so I'm trying to get everything in order with my 23' Marquis and
put some creature comforts in it. I plan on using a battery isolator
and I'd thought of installing an 8-D battery, but there goes about 130
lb.s in one solid chunk, so I'm opting for a couple or three extra car
batteries which will add up to about the same weight if not a bit
more, *but I can distribute them around the hull for a better balance.
Plus, I'm taking a friends Min Kota 24 v. troller for 'emergency use'
in case something might happen to the engine or drive. Therefore I can
switch a couple batteries around into series to make 24 for the
troller. It won't be much but it might help us to make it into
somewhere or out of the way of something heavy if need be.


I have a Nord refrigerator that got taken out of a camper that runs
on 12v.or 120vac. I bought it for cold drinking water, juice etc. and
it was cheap enough. OK so there's another 50lbs.. Plus I'm adding
about 6 -12 gal. of fresh water in a plastic canister like for an
outboard gas tank which will be supplied by an *electric pump to a
hand held shower head. *I figure I'm adding about 300 + *lb of extra
gear to an already heavy hull, (Not counting anchor) *but the boat
has a weight load *on the spec tag of 950 lb.


Now *I'm trying o figure out the best weight distribution formulas to
make it easier on the boat concerning handling, fuel economy (Proper
prop and trim tabs *comes next) etc.


Oh yeah, I forgot to mention I'm thinking on adding an extra 10 gallon
fuel tank out of a derelict boat I stripped out for parts.


And with all that , plus the wife and myself, I'm figuring to still be
under the weight limit on the boat.


How long are you planning to be out for one trip? A good cooler will keep stuff
cold for four or five days, and weigh a lot less than 50 pounds (empty).

John, the boat has 'captains' chairs in the front and the pilot side
is ok, but we're thinking on pulling the port side chair and
installing the fridge in it's own dedicatated and insulated cabinet
under it then putting a short chair pedistal and chair on top of it.
Actually from what I can tell this fridge is actually 120v with it's
own built in power inverter to convert from 12 DC to 120 AC. But it's
all self contained and water proof.

This is to utilize the space better instead of having a big cooler or
the fridge hanging out where you have to walk around it or me trip
over it (yes I'm clumsy!) Power is provided to it though the
auxillary batteries and those in turn are charged via a battery
isolator which will feed them and the engine battery off the
alternator. at the refridgerators 3.5 A draw, the auxiallry batteries
should be good to run the fridge over night that is if it doesn't need
to run 24-7, and the least that can happen is the fridge can run the
aux. batteries dead and still leave the engine battery alone. Start
the boat and you charge the engine and aux batteries at the same time.

Anyhow, We'd still be taking a cooler to keep the drinking water and
juice etc in and the food stuffs in the ice box.

Anyhow, that's my views concerning using a 12v refridgerator instead
of a cooler for main stay refridgeration.

Oh yeah, If we can hhole up at a marina with shore power for a night,
we can plug the box right in at the dock.
