I think you should compete in something called the micro transat. Its a competition held every year where autonomous sailboats try and cross the Atlantic unassisted. I think to date only 2 boats have successfully finished, but some have come close. It would be a really cool build/testing series.
Transat not transit btw. Microtransat
The best idea EVER!
I wish I could like this more than once
now you have my beer bro
That's awesome! I would ABSOLUTELY watch a series about that! Multiple series, actually!
We come for the RC, we stay for the tunes.
PLEASE tell me this is the return of your friends doing song covers for your videos. Always make me smile.
I cant figure out which is the best part of the video, the project or the song
amazing music indeed! so creative!
look up his cyclone series for more ^^
This Sail Remix fits so well :D
Super cool! Get some solar panels on the sail then it could sail forever 😎 also with the keel if you removed the front facing ‘spike’ off the bottom any seaweed would just slip off the bottom rather than getting snagged if you happened to catch any.
This made my Tuesday so much better! SAIL! 🎉
Just so you know, that wasn't a gas spill, its called a wind line. Gusts of wind and strength of wind is inconsistent across a body of water and sailors will use "dark" and "light" patches on the water to understand better where the wind is and what to sail towards. When the wind picks up it causes those micro waves or ripples on the water that make it appear darker, sailors will tack into those patches, aim to do any maneuvers within them, and sail from patch to patch avoiding the light spots. Great video but wanted to clear that up, a wind speed indicator would be really cool to see those patches and how they impact the apparent wind and tacking angle on the boat!
Try using RC boat hull tape, I use that on my RC boat to secure the hatch and keep water out.
the lighter coloured area was not the oil spill. Its just an area with less wind relative to the rest. As a sailor I can say that we use the dark spots in the waves to identify swells of wind, and we try to stay in them. Also, a few drops of gas spread really fast, it can cover a lot of area, so it probably wasn't as much as it looked like, because the layor is so thin.
I see now that you say the same thing about the dark spots later in the video, first watch then comment ig.
You can buy Marine sealant tape. Rooster 3M Slot Gasket Tape would be a good double-sided tape which is waterproof and can be used to prevent 100% of the water ingress unless it's coming from other locations.
I’ve always got slightly enthusiastic to watch your videos Daniel, content arrangement and transparency is as good as it gets
But I’ve become way more excited to hear what personal song or cover you’ll do a rendition of, skills of legend. We’ve got a true OG right here everyone 😎✊🏼
I am always really excited whenever you release a video. The mix of vlogging ang building is just awesome. Reminds me of all the projects I would love to make but never do
I'm a solo sailor of a single-sailed (junk rigged) sailing boat whose sailplan resembles your models a bit! Tacking through the wind can be an issue for me, especially when there's a lot of short waves hitting the hull. I can imagine your model has quite an issue. A foresail really helps with this on the commonplace bermuda rig. You might get some improvement from a two-element wingsail with a slot. Also, I recommend replacing the foam with butyl mastic tape if you want a better water seal. Looking forward to the next!
wow dude, rad mission, make it go to a lakeside bar and bring back a cocktail? re tape, try silicone (non adhesive) tape/wrap (easy to remove) or rv roof seal tape (super waterproof but maybe hard to remove)
I would say it’s not heading upwind at a high enough angle but I only sail big boats
And I would add a bigger more loose sail to catch better wind and heeling (leaning) is fine in fact it’s a good thing which means it is working great
You could also add wings to the keel/center board to make it shallower
Thank you for sharing this interesting and excellent project. I have a couple comments on the rigid wing and control system. I have been thinking about this problem for a while. In 1984, a friend and I built a 1-meter RC boat in your configuration. It worked quite well. First comment: I think you may be using too much “up elevator”. It appears that your wing pivots about the wing’s quarter chord. Full-flying elevator deflection should translate to about twice as much deflection in angle of attack. For example, five degrees of elevator deflection should yield about 10 degrees of wing angle of attack. This 2:1 magnification results from the downwash field in which the tail operates. Your symmetrical wing airfoil can handle roughly 10 degrees before stall, maybe less. In the video it appears that you are using much more than five degrees of elevator. This is quite apparent at 0:23 in the video. The result is that the wing is pitched up to and beyond stall angle. The wing may then make nearly as much lift as at maximum un-stalled angle of attack but will make far more drag. This drag is subtracted from the wing’s thrust, reducing speed and optimum upwind angle. I suggest that you do an engineering experiment. Find a steady breeze. Place the boat in a cradle pointed into the wind. Do an elevator deflection sweep and measure the wing incidence on the hull. What I expect you will find is a linear relationship up to wing stall. Then increasing elevator will provide little additional wing incidence. The break from linear to rollover will be close to maximum lift and a good operating angle of attack. My bet is that this will be to near five degrees of elevator. Adjust the control settings to limit elevator deflection to the determined value. This should give considerably better upwind performance. Second comment: Your boom-mounted mass balance decouples boat heeling angle and wing angle of attack. This is good. However, the low location of the boom is below the wing center of gravity. This means that the angle of attack _is_ coupled to roll (heel angle) oscillations. If you move the boom upwards so that the wing is dynamically balanced, roll oscillations will also be decoupled. If you place the boom even higher, you can passively damp roll oscillations. Third comment: It appears that you have a apparent wind direction vane at the bow. Consider if this sensor is redundant. The wing incidence with respect to the hull, in combination with the elevator deflection, can be used to derive apparent wind direction. The experiment from Comment 1 can be used to calibrate this relationship. Now, how to measure the wing’s incidence? I hope these comments are useful to you. This is an excellent effort. Thank you very much for all of your interesting and novel videos.
*** *** *** I have used for a long time, the famous Dragon Force 65 (also know as joysway), that for a lake (but I have used also on mediterrean sea!) is perfect (give you a lot of speed).
Flat water has less wind. You could use more sail area with a canting keel.
I was so insanely distracted by the banger cover I had to watch this one twice.
Hi there you mentioned about weed on the Keil. If you put a few degrees of back sweep and the main ballast starting from the front edge of the Keil then there's a good chance of the weed just sliding down and off
How about building a virtual anchor? Kind of like DIY/Cheap minn kota with gps that will keep boats on location. It would be super useful for many people. Should be easy enough with RC modules
You can redesign the keel to have its front point of the weight flush with the border of attack. It may require to rebalance your weight distribution and your center of effort.
There are some free plans for performant RC boats out there. Search for IOM plans. Another keyword is Racing sparrow. Strip planking thin strips of wood will cut down on the resin and fiberglass you have to lay down. A boxy hull shape from plywood also works well - the angles dig into the water and cut through the waves.
Finally, try to add two thermal probes - one at the surface and one at the end of the keel. Sea temperature is the kind of simple data collection that scientists love!
I have normal size sailboat. For long distance mini sailboat to avoid seaweed need to have full keel so boat is like shark fin underwater. And up top have catamaran hull and normal sail. Then see if can get to Alaska!!!!!!
Great content as always, but that music just took this to the next level!
OMFG the intro music. Dear god. SO FUCKING GOOD.
Amazing video, really hope to see more and perhaps see you enter some competitions 😁👍🏼
Can we just take a second to acknowledge the music in these videos? It's always perfect.
A wider hull would probably help since the ratio between width and length is always larger for smaller boats.
Wow!
Well done!
You should put some solar panels on top of it. With those and with fixing the leaks this boat could sail indefinitely.
The triumphant return of Truck Daddy Beats!
You need a better sailboat !
I have a DF65, it's kinda small to embark all your electronics and a bigger battery, but the DF95 could have that stuffed in. The upwind performance should be really better, also the stability in the waves, just need to find some place for sensors for the autopilot (might be able to hang them on the back).
Then there are a lot of much more expansive options, there's the 1 meter class which can hold a lot of stuff and are really fast but they can be so expensive, maybe find a used one.
I come for the video, I stay for the music
lets start this large scale. i know it probably alerDY EXSISTS but we can improve
It was awesome seeing you at opensauce! Been watching this channel for years!
I love the music, You should release an album...
Great mission / video.
Could you place that system on a catamaran hull with 2 weights (1 bow and 1 stern) that go across the deck on screws (much like how humans will move across a deck and hang over the edge in high cross wind environments)?
Now make it a trimaran! With hydrofoils! ❤ ⛵️
the alownation sail flute send me rolling
Thankyou for sail love you
possibly the best musical cover of the 21st century
love the music
very beautifull music!
Oh shit my new jam
Silicone grease on the foam would help a lot
The music was the best part, we definitely need more music!
brother, i just saw your video of the fpv seaplane, if this request is not too much to ask, can you try to recreate the Caspian sea monster?? its one of the coolest things ever created in my opinion
Yay! The songs are back!
That music tho..l. amazing
You should add some solar so it doesnt need the batterys to be charged and can run forever
0:32 It was when I realized what the background music is.
Is it possible to print an o-ring groove? O-ring material is available to make whatever length or shape you need and would definitely seal, reusable too.
The music is the best! Again! 😀
The music❤❤❤
7:27 oh nooo last cookie
Been waiting a while for this video ❤
eine "LED" RUNDUM BLITZLICHT
.. dann findest du es leichter (auch in der Nacht)
Suggestion: pressurize the hull to prevent water infiltration.
Fun project
If you can't manage to keep stuff out of the hull, how would you manage to keep stuff in?
Amazing!
Yoooo that music was 🔥🔥🔥
This song slaps.
Nice! Interestingly some companies are actually working on a commercial version of this - see oshen sail
Subscribed for the content, stay for the tunes :D
So dope!
Amazing 👍🏼
Thumbs up for music alone
Hey man love this project and your candor and musicianship! Been following this since catching up to the first vids but wanted to poke about the sponsor. I'd be curious if someone like polymaker might even be able/willing to sub out your sponsorship as they've picked up on a lot of ingenuitive engineering/tech channels and I could see them being interested in this content and engineering. Best wishes m8, excited for the next vid 🙏
you friend is too good at the recorder
When I was in Highschool band we played this song, I wish we would have played it like that tho :/
Took me way too long to realize what the background song was, lol.
Sail one across the Pacific or Atlantic!
sooo...where can i get that "Kazoos Can SAIL" track!?!!!
Great video.
Could the tiny tacks be due to strong water current?
maybe change the rudder to a twin rudder
Put solar cells on the sail for extra coolness.
Hockey stick tape works better than electrical tape
The firmware should be called ArduSailor
The next mission... fix the water ingress issues and go transatlantic!
SAIL!!!
lmao recorder version of Sail goes insane
Awesome video man!!!
The first song is amazing 😂
Would be cool to let a boat sail around the world in auto mode.
next mission: inifite range, just add solar panels to the sail :D
Cold the water get in around the mast?
i want that cover of sail..
background music soo good
bro is going to get hired by the department of defense to make autonomous vehicles.
is this Seattle? Looks like a pretty place to live
Scale up and solar!!
Nice job!
Can u not put solar on it to top up the batteries
chuck a few tampons in to deal with the little leaks
solar panel to charge battery for more range?
yeah the song
What hardware was used for the ardupilot?
Have you built an underwater glider yet?
