I think Emily's is better in terms of being an actual benchy, not a different model. But in terms of being a boat, this guys is better. EDIT: not taking sides, they each have their strong points
@@real_e Emily just sized up a model... She put effort into assembly, but this guy actually made a functional boat, and I think most people would associate this boat with a benchy. Don't get me wrong I don't dislike Emily's video but this is way cooler and much more functional.
Oh, I think Emily would fully accept that this boat is functionally much better; as, she's all about the janky, she's the queen of the bodge, the matriarch of the kludge

Hi! Small correction at the 27:02 mark: the foam inside the hull does not alter the displacement of the hull and, therefore, does not provide any surplus buoyancy compared to an empty hull shell. On the contrary, it adds weight and pulls the boat a bit lower into the water. It only provides any surplus buoyancy in the case when the hull is breached, since it won't allow any water ingress into the cavity inside the hull shell. As long as the shell itself is intact, the foam literally only adds weight to the hull and does not improve buoyancy one bit ;)
Thanks again for making a long format video rather than the 16 part series on how to “tap a nail”, even with forced sponsor ads it doesn’t detract from the entertainment. Thank you for staying original throughout, it really is appreciated
I feel I owe you an apology for my doubt/impatience. This was truly an impressive build that had far more complexities and challenges than I could have ever imagined. Well done! In the medium size range, you could print a benchy large enough to wear as a hat... but then it'd be capsized.
What was the thought process for picking the Archimedes chord infill pattern for the hull? Wouldn't grid be better since it would provide more area to support the front section?
So any infill that overlaps in the same layer is difficult for my extruder to push through due to the larger extrusion widths and is more likely to cause the part to come unadhered. The reason I selected Archimedes is because it is the longest most continuous infill, which minimizes non-printing moves. Pellet extruders exhibit more extrusion artifacts when starting and stopping.
Not only the largest Benchy, but the most functional. The last one made required ballasts to keep afloat, and that took away from the original design. You added a keel, but they are low profile and you can't see it in the water, so that's a big win!
@@DrDFlo Yes, it will take you forever to hand sort even 100 pounds. Also, I would put a metal detector in thee auto sorter just in case there fine metal shavings the sifters in it don't catch so that you can stop it since apparently anything can fall into the plastic production line.
Great project and great video! Im so glad someone finally made a REAL Benchy! But one criticism I have; really, displacement is the *only* way to float. It might be useful to think of the density explination in some cases, but it ignores the fact that the mechanics at play are exactly the same. It's just that density directly correlates mass-displacement to volume, without any geometry tricks. Also, floatation is independent of surface area; there is no correlation between depth of float/displacement and surface area. I imagine you ment cross sectional area?
You are right! Sorry, the reason I brought flotation vs displacement up is that if a boat is constructed from a material denser than water, then it will sink to the bottom of a waterway if it capsizes. I had an irrational fear that my boat would sink due to gaps in the layers or some other miscalculation and I wouldn’t be able to get it out. I appreciate you taking the time to leave this comment!
This is so cool! I tried to float a freshly printed benchy, but I couldn't get it to stay upright, it capsized immediately. I concluded that a benchy doesn't really work well as a boat 🙂 Color my surprise you are sailing around in one! Mega kudos!
I have been waiting so long for you to do this and totally does not disappoint! As usual, you went above and beyond and I can't wait to see this in person. Maybe you can rent it out to shows around the world! I know it would be a great attraction even if it wasn't floating. Great, great job doc. Thanks very much for all that effort. You have been promoted to Captain!🙂
We like people who design, modify and produce instead of producing ready-made designs. This was a really impressive project and I watched it breathlessly.
Hey, I love this project. Can’t believe your printer made it look soo flawless! :) good job. And I wanted to say you should try to make a speed boat next.
This won't win any speed benchy contest. Still top notch. It is very clear, that just a sized up original model won't do it and it has to meet certain features to be registered. Has some Steamboat Willy vibes.
50K in 2 days ain't bad. In fact, I'm pretty sure your most recent videos aren't hitting that many after weeks - and they deserve 10x more views as well!
You can buy handles for the Anderson connectors, and considering every use of them I see has a handle attached, I think you need them, especially for the larger sized connectors.
I met you all at the TN Maker Fest back at the end of September. I shared your video link with my robotics group who are always very interested in all things maker. You probably met several of our members at Maker Fest as well! Excellent work! Such a fun project and you have it very well documented here!
Ever since I first heard about 3D-printers I've always wanted to print a life-sized boat! You give me so much motivation to actually do this crazy project some day
Awesome project! In my opinion it's the benchmark for a life sized benchy. Very smart to add the foam into the hull, doesn't add much weight but prevents the hull from ever taking on water!
what you couldve done in the boat design is including a keel/center board inorder to make it easier to navigate against current and wind, but also lower the center of mass.
Print hollow and use foam like a real boat. Less weight and when you get a puncture that void won't fill with water. The foam is closed cell structural and adhesive all in one. Place a shallow heavy keel under the boat to counteract the top heaviness.
Longships actually had rocks at the bottom of the hull to lower their center of gravity since they were made to be able to navigate shallow bodies of water and the north sea. It could be something to think about if you ever do another boat.
if you do decide to do a version 2, I think it should be 2 segments wide and 4 long. and design it so you can fill the bottom of each segment with cement.
about 39 minutes in, I hope you aren't too sick of boats to not try and make a boat for peak efficency! Obviously had to do benchy for the meme, but I would love to see an attempt at a real deal badass boat! or even a submarine! amazing stuff!
It's always great to see people push 3D printing to it's limits for amazing projects such as this. Some might say that you've really pushed the boat out with this one.....
@16:00 No, no ship displaces more water than they weigh (at least once equilibrium is reached); if they did, the buoyant force generated would lift them upward, reducing the displacement. All vessels displace almost their entire mass of water, with a (typically negligible) bump coming from displacing air; this is fundamental to how flotation works. Even flotation cells work this way, since the flotation material displaces, but because it's aggregate density is less than that of water, even when fully submersed in water, the buoyant force is at least that of the force of gravity.
I love this. it turned out really well. I also enjoyed the quirk of his accent that made him pronounce hull as hole. Lots of tittering when he talked about flat bottom holes etc.
Bravo! Considering the original Benchy doesn't float, I'd say anything past that is an improvement. Congrats! I just noticed we're in the same city. I hope to randomly encounter this some time.
If the hull of the boat gets wider above the water line then the center of buoyancy moves further when the boat tips than it would with vertical sides. That’s why small boats don’t need a keel.
I don't know what's more impressive...that you made a full size benchy, or that you printed a benchy while sailing in a benchy! IMPRESSIVE for sure. BTW, what do you do for a living?
The reason I selected Archimedes is because it is the longest most continuous infill, which minimizes non-printing moves. Pellet extruders exhibit more extrusion artifacts when starting and stopping.

You need a lower centre of gravity. Deeper sides and ballast would get the waterline looking like a real benchy.
I love the boat's name.
This is TOO COOL for RUclips!
If the hull of the boat gets wider above the water line then the center of buoyancy moves further when the boat tips than it would with vertical sides. That’s why small boats don’t need a keel.

I'm curious about why you decided on a concentric infill, instead of a 3D structural infill like gyroid, which can also pass foam through it.
The reason I selected Archimedes is because it is the longest most continuous infill, which minimizes non-printing moves. Pellet extruders exhibit more extrusion artifacts when starting and stopping.
