Top heavy?
 
I've got an old boat very much like this one:

http://www.warnersdock.com/images/Fr...fores15yel.JPG

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?

This is a bad idea on several levels. Even if you can make the math
seem to work, the hull is designed to sit at a certain level in the
water so as to be safe during all aspects of operation while cruising
or in emergency conditions. Pitch a tent up there, or get a different
boat. It's like pulling a trailer that is too heavy for the vehicle.
The vehicle might get it rolling, but in an emergency can't react the
way you want it to, or the way it was designed.. You might get away
with it for years, but it could also get you killed in seconds. In a
nutshell, you have the wrong tool for the job. Change your plan, or
get a different boat... Just my opinion, but I am always against
modifying a tried and tested design..

It's not the weight. It's the moment.


I think it all depends on how the OP intends to use his "houseboat".
3-4 footers in the ocean? No way.
A lazy, small lake somewhere? Go for it.

I have programs here that will calculate any of it, but I was trying
to keep it simple for a layman.. At the same time, a note to the
OP... I defer to Eisboch in this case. He has much more experience
than I in this area... I have booklearnin' he has boats;)

It is on a lake. I wouldn't try it in the ocean. It's not as wide as the
houseboats around here, but it's not as tall either so I'm hoping it
will sort of balance out and be about the same thing. And when I
think about the cruisers in the ocean, with a flybridge, and then
a flybridge on top of the flybridge, and sometimes a flybridge on
top of the flybridge on top of the flybridge...how does all that work?

I have absolutely *no* experience in converting a small lake boat into a
houseboat.

Yes, but you have probably been in boats that size, or similar
configuration.... I have not..

Yes, you missed the first line which suggests that this is not his
boat, but one with a similar hull configuration..His boat could be
spotless for all we know...
