      I would be worried about water getting into the voids in the infill. You would probably have to fiberglass it to make it actually usable.

        Fiberglass may be overkill, but you would absolutely need some kind of sealing lacquer around the entire print or it will definitely fill with water.

          Oh I remember there was a guy that used it to make tiny 3d printed pressure tanks and put propane or something in them.

    Of course the Southerner headin’ out to the lake thinks of pontoons like a partyboat instead of a daggerboard or other weighted keel. LOL. This tracks with my life experience.

        This discusses the pontoons and the partyboat or “pleasure boat” as it’s referred to in the article. They can be very stable, but they need to be pretty wide and as they saw in the video, you still want the boat to ride pretty low in relation to the size of pontoons you use.

        A daggerboard is a type of centerboard that can be pulled up through a slot in the hull. Centerboards are mostly used in sailboats, but the reason they’re needed is that in terms of forces acting a boat, sailing makes it top-heavy as fuck. This benchy is naturally top-heavy, so having a fin sticking down in to water helps, and having a weight on the end of it helps even more.

        Ultimately, I imagine they ran across most of these concepts in preparing the video, but it wasn’t as fun for their intended audience as a silly low-stakes 3D Printing YOLO meme, and TBF the 3D printing seems to have come off very well.
