The Craziest Hydrofoil Concepts You'll See Today [Trailmakers]

[@Krokmaniak]

Basically: Catamaran uses buoyancy like normal ship but has 2 hulls in the water. Hydrofoil uses lifting force from wings in the water to lift the hull out of the water after reaching certain speed

[@evernewb2073]

close: the hydrofoil is the system for lifting the craft out of the water, catamaran refers to designs with 2 main hulls. there is no reason that a boat can't be both designing a hydrofoil as a catamaran layout makes particular sense in videogames because physics is always going to be a lot more napkin-mathy and your tools for interacting with the game physics are a lot more limited making the stability of the layout rather helpful

[@Xeno1798]

@@evernewb2073 That last part is the specific one to focus on for the question. Catamaran's aren't hydrofoils. A hydrofoil can also be a catamaran given the foils are on the extended hulls

[@evernewb2073]

@@Xeno1798 I...um, yes? your' phrasing says you are providing a counterpoint in a nice clear matter of fact manner but what you are saying agrees entirely...am I missing an interaction with the exact phrasing in the video? I made the comment after it was finished so that sounds fairly plausible. I did leave a bit out: it looked like a lot of the "hydrofoils" in the video were simply...what's the boating term for it again...planeing? skimming right up on the surface of the water with only the bottom tip of the hull engaged (not a hydrofoil but similar design goals and methodology) usually with some system to maintain engagement cleanly like how racing boats form a vacuum under themselves or the control systems in some of the builds in the video

[@evernewb2073]

@@Xeno1798 oh! oh I think I get it: hydrofoil and catamaran aren't their own similar but unique things in and of themselves like, I dunno, hovercraft for example. like how a "jet" is really just a shorthand term for airplanes with a specific category of engine acting as their primary powerplant. aaand now I'm wondering if you can get away with calling something like a P-38 a catamaran, heh.

[@maxcalabrese5962]

@@evernewb2073 you're very right about it being napkin-mathy. What you seen this game is very unrealistic. In real life a hydrofoil will stop lifting as soon as it pops out of the water - when it reenters the water it has to overcome the resistance provided by the surface tension as well as "restarting" the laminar flow around the foil. My experience is just with kite foils but breaching usually means the board slamming down hard into the water and losing all your speed so its something you want to avoid. The exception here would be if the hull has enough lifting area for the boat to actually fly - an idea that was tested a few times with seaplanes but that turned out to be a horrible combo.

[@Nefrea]

Hydrofoil literally refers to the "wings" shape in the water. Think aerofoil. So a hydrofoil boat is just a craft that has "wings" that go beneath the surface.

[@MurseMorris]

[@the_worst_youtuber_ever8583]

Second time

[@edwardgravit2072]

A catamaran has two hulls, (trimaran three, etc.). A hydrofoil raises a hull out of the water. There are examples of foiling catamarans (see America's cup 2021), but a basic catamaran has the two hulls remaining in the water with a structure and usually a trampoline connecting them, whereas a foiling boat has a hull that is raised by foils. Hulls are buoyant whereas foils are almost always just aerodynamic.

[@darklingnz8017]

Lol couldnt have said it better myself. The new hydrofoiling Americas cup boats are insane to watch and are incredibly fast. Even in the water they move faster than the regular boats they used to use in the comp. Getting to thw point where tjere are loads of things that foil. Theres a vid of a dude that used a foiling board to recreate an aladdins magic carpet scene and it looks great.

I remember making a 6 powerscore hydrofoil-ish vehicle that can go 600km+. Was pretty proud of it since it was pretty big and used no glitches. Managed top 3 in the scoreboards, too.

[@69production60]

I would say catamarans aren’t hydrofoils because the part that stays in the water and the part that stays out of the water stays the same when your moving and when your stoped

[@tropicalvikingcreations]

Hydro foils don't need moving parts to count as a hydro foil, you can have the WI vs attached at a preset angle to do the same thing. However compared to one that does move it affects the efficiency towards the ends of the transition.

[@69production60]

@@tropicalvikingcreations I didt mean moving parts I meant when you have a boat with a hydrofoil it doesn’t pop out of the water till it gets at speed a catamaran’s body stays out of the water even when it’s stopped

[@supersmiley5587]

I think the difference is that a catamerans main body (the middle part) is always over the wa'er even at 0km/h but a hydrofoils body is ontop of da wa'er at 0km/h

[@anteshell]

Hydrofoil "flies" in the water. Catamaran just floats on it like normal one bodied boats. The difference between a catamaran and normal boat is just the amount of floating bodies.

[@neogalford]

MK 5 is on the workshop. I've fixed the high speed dipping issue; mostly. Still committed to building the fastest non glitch, wing turning boat. I do have another one that uses glitches and has a faster turning method. I think I uploaded it as the Hydrofoil Mini.

[@gokselaras9002]

I made a boat with 1 power core which is one underwater propeller with the top speed of 278 kmh and easily goes up to 250 kmh even in short distances. ( No glitches or bugs, full aerodynamics ) Edit: For the ones who wanna test the name of the boat is: 1 Prop 277-8 kmh boat

[@MrMattkid]

Something to note in that definition is a hydrofoil is specifically a wing that reduces the drag on a boat by lifting it out of the water. So calling a boat itself a hydrofoil is actually the wrong use of the word. In summary: A boat is not a hydrofoil, it can have a hydrofoil on it to reduce it's drag. However it is still a boat not a hydrofoil.

[@Tyfu39944]

7:13 Scrap missed the PERFECT opportunity for the Lego brick break sound effect

[@UR_Mind]

I'd say most of those were hydroplanes, a boat skims across the water with a small part of its hull in contact with the water at any given time. A hydrofoil would have the hull contact the water, and it would require some structure below the water to lift it out. A catamaran is a twin hulled boat, which can fit into either category above.

[@karstsn]

I miss this guy, i haven't watched him in 4 years.

[@gamerraider2600]

[@THESLlCK]

6:05 is quite clearly a hydrofoil. Any boat that uses a flat surface to create lift to push itself mostly or entirely out of the water is a hydrofoil. Look up top fuel hydrofoil boat racing. Same design, but they make 10,000+ horsepower minimum to compete. Some hell of a sport.

The way you win is which ever team lives the longest and the way to win the first 2 is to shoot down the enemy 2 person plane in with the fastest time. 4th time posting this and if you think its a good idea can you please like this.

[@1mariomaniac]

The 0-drag hydrofoil around objects just reminds me of F-Zero X lol

[@Not_Dane_Heart]

A catamaran is a multihull boat, this means that it has more than one hull allowing it to lift it’s center out of the water. A foiling boat has wings on the bottom which push it out of the water at speed. This means that they only work once that speed is met while a catamaran always has less drag, so a catamaran is not a foiling boat. However, you can get a foiled catamaran which would have a very high top speed and would be the sort that would win races such as the fastnet.

[@Not_Dane_Heart]

Hope this helps

[@Codename_Shadow]

[@Snarfyy]

Strange vehicle for you to check out - the soviet Ekranoplan. It’s a large boat that uses aerofoils to lift it completely out of the water, much like a hydrofoil but more extreme.

[@robmonks8930]

A catamaran is a type of aquatic vehicle. A hydrofoil is a feature of an aquatic vehicle. A racing catamaran can be equipped with hydrofoils, raising both pontoons out of the water.

[@BubbyGamingOfficial]

I miss that intro theme

[@RobertCondonSunnyTurtle]

Hydrofoil is just any lifting surface under a boat. You might want to look at Australia II from 1982 America cup. There was some arguments there about hydrofoil state. But for sailing I think the you need have a lifting upwards force to be considered a hydrofoil. Would love to see a sailing hydrofoil build there are so many variation in hydrofoiling sailing I love it

[@fun-damentals6354]

try to build an ekranoplane , a russian water craft which used the ground effect to stay just above the water

[@K41-g6p]

a hydrofoil is defined by its use of airfoils submerged in water to provide a minor amount of lift, enough to push everything but the wings themselves, and the underwater propellers, out of the water for minimum drag. a catamaran is defined by the ship possessing multiple hulls resting in the water, rather than a single hull, that together provide more stability. if a regular boat is a wide wheeled motorbike, then a catamaran is a car if that makes sense. something interesting is the idea of the ekranoplan, which as far as i am aware is the official name since the only other one i know of is 'ground effect vehicle'. this is basically what happened when you take a hydrofoil, and give it enough lift to bring the wings out of the water as well, since water resistance is affected by how much of the ship rests in the water, if the ship lifts out of the water completely, there is nothing for water to resist. the result is a 'too fat to fly properly' aircraft.

[@RichardSJTol]

Pls make an episode on flying, boating and submarining on highseas with these creations and ones you made in past episodes it would be soooo cool

[@nateolmsted22]

[@bboss1738]

I think a catamaran has floating parts touching the water while a hydrofoil has non floatable hydro dynamic pieces lifting it

[@goldfishwings]

I would define a catamaran as a boat that lifts the majority of the craft out of the water using buoyancy, where a hydrofoil lifts the boat out of the water using hydrodynamics.

[@DrJiKentauriuzHero]

A hydrofoil is an underwater wing that lifts the boat's hull out of the water. A catamaran is a boat with 2 hulls.

[@Snarfyy]

A catamaran has two boat hulls and works like a normal boat, a hydrofoil (like an aerofoil on a plane) is a wing that uses fluid dynamics to lift the hull(s) out of the water. A catamaran would not count as it wouldn’t have any hydrofoils and the hills would still be in the water

[@rainbouncebecable5047]

I am not an expert on boats, but last time I checked catamarans just have two hulls on the sides of the main body rather than normal boats having the one hull under the main body. So technically a regular catamaran would not be classified as a hydrofoil because they are not wings and they don't lift it out of the water any more that where it is at standstill sitting in the water

[@thegamingentity8460]

Finally workshop hunters is back

[@tropicalvikingcreations]

The comments already did a decent job and Scrapman seems to get the idea so there was no need for me to comment but I wanted to anyway XD. But yeah basically catamaran is a multihull body while a hydrofoil is a hull being lifted out of the water by wing surfaces. Not all of those were hydrofoils as there was no lifting wing body but instead used a plane effect, which is very different an just makes it a speedboat.

[@vale.44peru]

My guess with the difference between hydrofoil and catamaran, is that an hydofoil is a wing thus it produces the upward force needed to sustain the ship weight via lift, while a catamaran uses buoyancy and archimede’s principle, keep in mind that this is just an educated guess, im not an expert

[@lemontrout9434]

the catamaran at 6min is plaining rather than hydrofoiling basically the shape of the hull pushes the water underneath pushing the boat up meaning that you have less resistance and go faster more efficiently and fun fact if your hydrofoil comes out of the water (unintentionally) u will almost most certainly pitch pole (capsizing but forwards) edit look up the nacra 17 for a hydro foiling catamaran

[@paritybit7830]

For that rocket hydrofoil, I'm gonna say the backwards cockpit is totally on purpose. I'm betting the creator is a keyboard & mouse player who wants and expects W to be up and S to be down. At the least, the built-in flight control drives me crazy for that exact reason... I hate flying with keyboard and will grab the controller if I get into anything that uses cockpit flight control. Maybe I was blind, but I couldn't find anywhere to change the control scheme, and on keyboard I really expect W to pitch up and S to pitch down. Pull back to pitch up and push forward to pitch down feels natural on a controller, but on keyboard... up=down/down=up just doesn't work for me, not on arrow keys and not on WASD. When I can I'll always flip it. Similarly on controller I always have forward=look down/back=look up, regardless of whether it's a character or vehicle that I'm controlling in the game. ... also, it's just possible that the creator actually does use a controller, and has just been trained by too many RPG games that forward=down and back=up, which is the default orientation for basically all of them anymore, much to my annoyance. But I tend to keyboard & mouse whenever possible except when driving vehicles... when driving vehicles the analog controls are, IMO, really desirable.
