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.
