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.
I know some of these words
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.
Thank you. the whole time I thought, “What happened to the keel idea?”
So I think the little bit they added is still there, but it just wasn’t nearly enough. TBF, there’s nothing inherently “wrong” with making a boat wider rather than deeper (e.g. the aforementioned partyboats), but as they saw it doesn’t scale quite how you’d think, and much of the benefit they got from the pontoons that did work would have been there even if they’d left it flat.
Also, I guess the apparent half-assery is part of the appeal? I am not familiar with this Emily. I kind of assumed it was going to be an Emily Calandrelli video, but then I’m a dad who’s watched a LOT of kids’ Netflix.
Her videos used to be mostly about 3D printing Iron Man suits, but she found a (likely more profitable) niche doing sillier things with 3d printers and her engineering knowledge.
You know what boat stands for right?
Bust Out Another Threedeeprinter
I’ve actually been thinking of printing a kayak like this.
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.
Honestly, some two part epoxy smoothed around it and you’d be gtg. And getting high off the fumes it gives off for the next three years…
watertight boat and a free high? seems like a win win
The 3d gloop mentioned in the video is a solvent that’s used for welding PLA. You could definitely use that to properly seal it. And being built from blocks like in the video (which is due to a limitation of the size of a 3d printer) means that any leak would probably be limited to a single block at a time and probably not catastrophic.
I suppose that would work too, just solvent and then smear the outer walls of the boat. PLA is not exactly water safe though and will break down/become mechanically weak with long enough exposure. So it would be better to ideally seal the plastic entirely with a laquer
Alternatively, build a siphoning drain tube so your movement over the surface sucks the water out as you go.
Then you just have to not stop paddling.
You could also use a hydrophobic impregnator. Dichtol is a pretty good impregnator for 3d prints.
Oh I remember there was a guy that used it to make tiny 3d printed pressure tanks and put propane or something in them.
It always irritated me that the most prolific benchy design was a boat that isn’t useful for anything (besides being a benchmark itself) and doesn’t even float.
almost unwatchable due to the use of the word “bro” non top. Otherwise it was fine.
Bro , it’s fine. I swear bro, don’t worry bro… It’s just a prank bro
They clearly weren’t a Vince Russo guy
Y’all are the worst.
Ah c’mon bro don’t be like that, we’re just foolin’ around with the bros!
I’m sorry it doesn’t cater to your specific linguistic preferences, bro.
I think you’re being a tad oversensitive here, bro.
