When you have to go all the way around the long way to tack upwind, that's called wearing. It's how the square sailed ships usually did it, since it was easier on the hardware, and less effort for the crew. Also, square sailed vessels were not always the most windward in the fleet. The three masted boat is not a schooner, which has gaff rigged lower sails, and also loftier masts as you proceed aft. The sloop was indeed a sloop. Add a headsail (jib) though, and she would be a cutter. Your upwind problems were likely causes by insufficient lateral plane area (keel needs more surface area). Also, the usual guidelines for proportions won't work well, as you've scaled down to, basically, a different set of rules/guidelines. The sail on a boat works just as the wing on an aircraft: pressure differential. For practical knowledge of sailing, nothing beats holding the tiller in your hand. I have plans for a small, inexpensive sailboat you could probably build in a weekend. It's a catamaran, because the other road to stability is width, rather than low down weight. Please note, however, that the mutlihull approach can only keep up with the deep keel approach about 95% of the time. After a knockdown, one person can right even a good sized fin keel sailboat. A catamaran, having no low down weight, is just as stable upside down as right side up, which is little problem on a lake, but, out at sea... Enjoying the videos immensely. Keep up the good work!
You are totally awesome! When I was a kid, my friends and I found a discarded SURFBOARD...stuck a broomstick mast, and a bedsheet sail...set it out to sea...⛵️....can only imagine what the coast guard thought when they came across it!
This may have already been mentioned. One of the main reasons you were having trouble sailing upwind was your keel design. It should basically be designed as an underwater wing of sorts. Take a look at your model sailboat keel and compare it to your boats and I think you'll see the issue.
Not sure what I laughed at more... "blow me 2" or "eight" unexpected laugh was unexpected for 2x4. If one wanted to sue over it I guess you could say it is actually 5.25 since that lawsuit that forced them to give actual dimensions of a damn 2x4 as 1.5x3.5....

11:01 - during this abrupt change of course the wind throws the sail to the other side of the boat which can damage the rigging. i experienced this myself on a windy day at a sailing club when the rail whacked off my glasses, but luckily they did not fall into the water. to avoid this i learned to turn the boat the other way around (with the nose facing the wind side instead of the rear facing the wind side) until the boat faced the other direction.
If you try this again, make your keel have more vertical surface area and sail a zig-zag route (tacking) into the wind. The keel/centerboard of a sailboat helps convert the sideways force of the wind into forward motion.
the ballast ball does kind of keep the boat from tipping over but it is actually is called a keel and it makes it so the boat goes straight without it, it would just drift sideways. and also most keels are shaped like an aerofoil what helps it a lot and that is why sams boat did not go upwind in the second race because he used a straw and that will not work. Just some tips so if you do it again you will bet him even more. :)
The key to sailing is to first find out how close to the wind your boat can sail and still be going forward. .... then tack and go toward the wind at the same angle as you did before. ..... the maneuver you talked about to turn your boat is called a jib. when you go with the wind to get on the other tack. ..... This can be done by all sail boats. It's a great sport in full size or R/C boats.
No sail boat can sail directly up win. Jus bring your sails in close to the boat and when they start to flutter turn your boat away from the wind until the sails stop fluttering. When you run out of room tack to the other side of the wind and off you go as close to up wind as your boat will sail.
Some years ago I made an RC sailboat from heavy balsa and RC car parts. I attached the drive motor to a spool to let string out or snatch it back in really fast. And then I attached the steering motor to a rudder. It was fun, though sluggish in the water since I balanced it with a bit of chain instead of a long ballast bulb like yours. It eventually got damaged and I didn't want to fiddle with it anymore. Though I DO wish my kids could see it, so maybe I'll build another sometime.
I think an improved keel would help both boats. I might also try independent sail controls for the fore sails and the aft sails on the schooner so that the aft sails can be pulled in all the way to help bring the back of the boat around when tacking into the wind. Those boats definitely look like fun, I have a Victoria that was much improved with the addition of new sails from Carr sails, the stock sails from the late 90s kit were terrible.

That's because sailboats typically don't sail straight into the wind, they TAC from side to side into the wind in a diagonal crisscross path to move upwind. If you want to get an idea, try ATLAS for it's sailing dynamics. They use wind and sail direction to steer the ships the same way you would a real sailing vessel.
Peter this brought back memories of my childhood as well, although we only raced from one side to the other in a pond. Sure do miss those days it was so much fun. My friend and I moved away and only saw each other one more time. They were good times.. thanks for making the vid and bring back those fun times. Take care..
Makes sense to me that the schooner was better in the maneuverability test during high winds. More sails on shorter masts usually means less keeling for the same sail area, and was thus less likely to capsize than the sloop with a much taller mast. Downside is more standing gear to cause drag, so in ideal conditions and with properly trimmed sails, a sloop will generally be more efficient when sailing to windward than a schooner.
The basics to sailing....sail into wind you will stall so you must "zig zag" or tac. Going down wind let your sail out. When going across wind pull your sail on. I know its not that easy but hey its a good start
When sailing upwind you go zig and zag up the wind. To turn up wing the front sail gets pushed into the wind to push the bow of the bout around. Its a bit complicated but definitely replicatable in RC....
That weird 360 move is call a "jibe". Helps when the wind cause trouble on the upwind tac. Gives a relaxed monument by letting the wind come across the stern so you can set the main sheet for the next tac. Anyway that was good sailing fun I bet.
Hey I made one of those about 20 years ago, 8" long, cat rigged with alloy mast and clingfilm sail. 2x NiCad AA batteries for both servo power and keel ballast. Wanted to practice sailing. Also dug a small pond in my garden to sail it on. Worked OK until the pond filled up with weeds. Over the years since then I've upgraded to a 30' ketch on the Irish Sea.
You need a longer and broader keel for the schooner . You could also add a bow sprit and put on headsail, this will allow the boat to point to wind better, plus the broader keel should address some of your issues. You will loose a little steering it won’t turn as quick but you can add a deeper rudder .
The trick to sailing upwind is making a zig-zag 45° off from the wind’s direction, and tighten the sheet until the trailing edge of the sail starts to flutter. Think of it as a wing: when it flutters, it’s stalling. Also, if you are only running 2 channels, nix the jib sail, otherwise set a 3rd servo and channel to tighten/loosen it separately. If you want to do a 2 channel, a setup like a Lazer (brand of small sailboat that is great for beginners) Finally for some extra fun, make an adjustable daggerboard on yet another channel so that you can lower drag at the expense of stability, or vice versa
I have a good idea for your sail boat to be able to sail upwind. You forgot to add a daggerboard (center board) which is one of the main reasons why you did not have enough power to sail upwind.
Hi Peter, my name is Leonardo. I'm student of Naval and Ocean Engeneering from Federal University of Rio de Janeiro . Analyzing your project, he could have been better doing two changes, first is a more hydrodynamic hull, and the second is a higher weight in the keel.
The hull shape certainly will have made a difference, but another couple of factors that will have influenced the maneuverability of your ships would be sail size and tautness. Peter's boat had much smaller sails, meaning that it was able to more efficiently utilise the energy the wind gave it. Rather than simply being pushed backwards because of the large surface area of the sail compared to the keel, it was able to move forward while being angled more towards the wind. This is why sails would be reefed (made smaller) in a storm. This could have been further improved if you had had any control over how taut the sail was. You had some minor level of control over your sails using the servo, but there wasn't much stopping your sails from billowing out or flapping around. That means you're losing most of, if not all, the energy the wind is providing you, and you will move much slower. Greater control over your sails means a sharper angle to the wind, meaning it'll be much easier to reach and maneuver around a buoy.
Peter: *sets tiny wooden sail boat with a dead mouse on it and loses it* (Washes up on shore) Random 4 year old kid: *finds the boat and screams because there is a dead mouse on it*
Next, you need to combine the sailboat and hydrofoil projects and make a radio-controlled hydrofoil sailboat. My interest was sparked in the late 1960's by B.K. Smith's "The 40-Knot Sailboat". The "Yellow Pages" hydrofoil looks to be similar in design to Smith's original design. Using rigid airfoils should make remote control somewhat easier than using traditional fabric sails.
I think sail and rudder need to be independent , that way you can also run rudder opposite side sail is on to help with up wind and keeping boat strait. nice video!

Love your work dude. Even your add for the sneakers was entertaining.
Your weird 360 manouver to go upwind is basically tacking (sailing left and right, 45-90 degrees of the headwind)
Such a cool project. I'll have to try this with my kid He took sailing lessons a few summers ago, maybe he still remembers how to go upwind.

Needed a better keel to go upwind.
Not enough to have a ballast at the bottom, you need a large flat surface to help keep the lateral movement down.
