    May be an idea that gets responses:

    How about building a hull around a 40' steel shipping container?

    Using these has been discussed on these forums before.

    Sailing barges (which is what you're basically asking about) don't necessarily sail well but they do sail, though you'd probably want some fuss fore and aft to have finer ends.

    There are for example long shipping containers that I've suggested (with the addition of a aforementioned bow/stern extensions) could be used for a catamaran houseboat.

    For a monohull you might set one on its side, have it be a bit wider and not as tall, to improve stability and get a somewhat shallower draft. Not sure how that would affect things structurally.

    One worry I would have is if you had a shell to fair the hull (or get some rocker) that it would provide a place for moisture to collect and rust to set in.

    Most containers these days have a compressed wood bottom, so is not waterproof for a start.

    There are bigger yachts designed to fit into a 40 foot container
    http://www.containeryachts.com/

    but they have to have a bolt on keel to stay upright.

    Bear in mind, that the steel for a yacht is the cheapest part of the whole project, so having to work around the corrugated sides will save very little in time or material costs

    Thank you Mr. Watson.
    And what is the good news?

    Hey, I'm a bit dumb possibly, but is this about designing a boat to fit inside a 40' container ?

    No. I just mentioned one that could to illustrate the buoyancy issues.

    OK, so it is about a 40' container being the 'core' element, and a boat hull is built around it, somehow ? Sounds more like a double-hull really.

    Who can say . the vague concept could be anything. Container boats have been discussed for years in these forums and no benefit for using containers in any way has been found for serious boats. Maybe as emergency flotation with a bit of work but little else.

    Must be a case of people seeing a cheap "box" and trying to figure out what use to put it to, but making a boat around one is a bit of a stretch. Not as crazy as the train sub, though ! Perhaps "son of train sub".

    The idea would be to build a hull around a 40' steel container.

    What advantage(s) do you see, in this ?

    Better to build a boat beside the container and use it for storage. I can't see what you could achieve trying to make a boat out of one. If you bought a good container here it cost about 2500 plus delivery. That would buy a lot of ply and epoxy.

    Advantage: (maybe)
    availability of container
    foam filling between hull and container
    structural strength

    there might be more

    disadvantage: (I learned here) corrosion between foam and steel by saltwater

    Difficult to find a place to build anything.
