Will my boat plan float?

[Dr.Smart]

Hi, me and my friends are making a barge for us, will it topple over, or sink?

Thanks!

[Dr.Smart]

Um, anybody want to response?

[TeddyDiver]

What's the hollow space below?

[Submarine Tom]

Will it topple or sink?

Well, it might.

Tell us more about the design and it's construction.

Air. So that it will float.

It will be wielded by me, and it will be made out of aluminum.

And what sort of engine do you think we will need? We want it to go at least 10 miles per hour.

[Dirteater]

Well Doc,

If I see it right?
its about 12 feet high and 25 feet long. and how wide?
It looks like you have 6 x 25 feet of "air" for a hull? (weight perhaps?)

It'll float fore sure, but I'd almost think it would float better upside down.

that's quite the drawing to try to read my friend.
Just trying to help you out and clarify.

Do you mean contained air, like a balloon?

Yes, it is 12 feet high, 25 feet long, and 12 feet wide.

And 6 feet on the bottom is the "balloon" is that to much? Could it be less?

How come it would float better up side down?

Exactly.

Hi Doc,

Well, now I see the picture a little clearer.
ie: I didn't know it has a balloon/apron?, (kudos to SamSam),
Please understand Doc, I'm no engineer.
and when I see your drawing it appears top heavy.

too me, its kind of a huge raft?
why not a pontoon boat approach?

Just a thought and a reply,
I have to leave it to the pro's from here.

thanks,
DE

Do you think it could blow over?

The bottom drawing is the front view.

[Zurael]

it'll float as long as it displaces more weight in water than it weighs
but a square hull makes a lot of drag
also with all the weight above the waterline I would think it would be inclined to topple over
if the width increased with height I would think it would be more stable, but I'm no naval architect

[kerosene]

it would float better upside down as a lot of the weight is way above the "cavity" that provides the buoyancy.

25ft long boat - 10mph - no way in displacement mode - very inefficient - needs way more power than if it actually looked like a boat.
Structure is not that short of retarded.

You don't want weight that high - no reason to be near that high - even if you wanted a closed cavity for buoyancy.

Why is that area closed anyway? so it it "unsinkable"? I bet it would be easier to bail if a rock pierced the bottom if it was actually open. Now all will happen is that you see that the boat is swimming "kinda deep". Until it swims real deep.

[Dr.Smart]

Actually I want it to be more of an unsinkable raft. I am a beginner wielder, and it is easier to make a square then a round boat.

What if I make the front more of a triangle?

[Dr.Smart]

Hi, here is exactly what we are wanting to build:


Does anybody have any good plans for a beginner wielder? And is that small enough to be puller by an suv?

[PAR]

Nothing personal Dr.Smart, but you don't have the skills to design a boat, frankly not even close, so lets move to the availability of plans.

Metal boat plans aren't especially common in trailer boat sizes. Aluminum usually is too thin to weld in these sizes and is riveted instead. This said there are a few, start here;
