WAFA will spend all week on that one.

that I'm trying to make into a mini-houseboat,
sort of like a camper. I only expect to have
about 200-300 pounds in the roof and walls,
and the roof will only be about 48" above
the gunwale. The hull will weigh a *lot* more
than what is added, so shouldn't that alone
be enough to keep it from being top heavy
and flipping over? If I add weight, like a
couple hundred pound bags of sand down
in the hull to counterballance, shouldn't
that take care of it? If so, should they
be placed on the sides, or in the center?

Use a tent! The thing will add only 20lbs to the boat, is easy to remove,
and can be configured all kinds of ways. Check LLBean for a tent that will
fit. Put a couple thermarest mattresses on the deck and you're good to go.

David,
Get a book on Naval Architecture and read about GM.
Every boat has the center of gravity above the center of buoyancy.
Weight added alone might not keep it upright.

Matt,

Haven't heard from you in a while. Nice to have you back.

I remember that you knew my boat in her previous life. Take a look at her
now

http://home.maine.rr.com/rlma/Boat.htm

Have you heard anything about the previous owners? Last I talked to them,
one was having some medical issues and they weren't sure if they were going
to be able to go cruising. I've now lost contact.

Container ships sometimes have a slight negative GM, or used to 30 years ago
when we would watch them come down the harbor with a slight list, make the
turn, flop over, and continue on to sea with a slight list the other way.
They have enough freeboard and flare in the ends that the righting arms
would go positive after a couple degrees of heel. This loading made for
minimal rolling and least strain on the upper layers of boxes. You can only
get away with this in a very large ship though.

The mini houseboat fellow won't get very far trying to apply what he reads
about GM in a standard textbook to his problem. He should weight a sheet of
plywood or get it's weight, calculate how much he needs to make the cabin,
add about 50% for framing and other stuff, and then add the estimated weight
of anything else he plans to put on board. Next put a table on board with
the legs propped up a bit to get the top to about 75% of the cabin height.
Pile the table with the estimated weight and go aboard. If the motion feels
drunken and sluggish with very slow rools, the boat will probably be
uncomfortable as well as dangerous. Keep removing weight from the table
until a couple of people can walk around with the boat feeling solid and the
rail getting close to the water. Then figure if he can build a cabin
within that weight allowance.

Strong winds are another issue but it sounds like this is a lake boat to
spend most of its time on a mooring.

Roger,

I like both your practical answer and your pictures.

You're cruising my old stomping (sailing) ground. I do miss the coast.

Tom had recovered well and was looking good last time I spoke to him.
I'll send him the URL to your pictures.

I was kind of hoping that this guy would get the plan that there is a
whole lot to know before his question could be answered effectively.

A tanker I was 2AE on had a negative GM and a slight port on the way
out. Every wave made it snap to Stbd, stall a couple of seconds and
snap back. It was all a guy could do to stay on his feet. We did lose
the fire in one boiler, but the FM lit it off the bricks. My chief
called the bridge and told them if they tried to make for sea this way,
he would shut them down. - They believed him, but he still had to
listen to a bunch of griping because we lost two hours while they
finished correcting the ballast.

Well, at the risk of being simple. I still suggest it's the wrong boat
for the job. He just needs to start with the right boat. He can
justify, defend, and make any excuses he wants.. Still water,
whatever.. But once you leave the dock, things can change quickly to
something you have never seen before.
Anyway. Have a great fourth, go out in your boats for me Scotty
