Sorry, we were a bit in a rush so these are the only shots we filmed. You can find some photos on www.proas.is. Basically it's a massive steel frame that we welded and got galvanized. The wheels (cadkat catamaran slip trolley wheels) are mounted in between the hulls for better maneuverability. The passage through the dunes is quite narrow and we can not make it wider for conservation reasons.

@proasisproject2 ай бұрын
@@gregory1778 Fore my taste it would be too much effort. Preparing everything takes time (at least 1h until the trolley is under the boat) and is a job for at least two due to the weight of the trolley+wheels. Taking the trolley off the boat in the water is surprisingly difficult due to the buoyancy in the tires, again a 2-4 person job. We take everything out and off the boat before we move it to reduce the weight. Even then we are close to what the tires are rated for. Bringing all the stuff down the beach and setting it up takes about 2-3h. So a clear no for taking it in and out on a daily base. You could use stronger wheels (old car wheels for example with stainless steel ball bearings) to support the entire weight and safe on that time but it would still be an annoying job to move the trolley under the hulls/take it off and make sure it sits on there nicely etc. I'm happy we have to do it only twice a year!

It's lucky that western (white) culture isn't so zenophobic and has shared our knowledge of all our technology with the world..medicine antibiotics, communications technology, mobile phones, internet, sanitation, running water, himan rights, westminster system of law etc, if we acted like the Marshallese with their canoe tech the world would still be in the dark ages!

Been following this project for quite a while and somehow missed this video, great explanation on how a shunt works! That rudder linkage design is super cool too. I imagine that a great deal of time and moving about could be eliminated through the use of a "tack track" as found on some other oceanic lateen-rigged proas, but I understand that for the Proasis project simplicity and low cost of construction were key considerations, so it makes sense to stay traditional in that regard.
@proasisproject5 ай бұрын
Thanks, that's nice to know :) Yeah, we keep it like this on purpose. As simple and possible. We don't mind the moving, it's really much less of an effort than it looks like (with the right technique of course). We use proasis quite often for story telling events about climate change and other ocean related activities. For the guests it's always a sensation to feel the wind in their hands and move with the waves and the boat. To be honest I like it alot too. Having a track might make the shunt a bit faster by forcing the sail to the other side but the direct connection is lost. The feeling of a manual shunt is difficult to describe but I don't want to miss it.

Well you asked - I'm always concerned in videos when the music swells and a soothing voice leads me through an experience - especially when I'm told what to feel about it. Turn off the sound and the whole procedure looks involved, janky, and cumbersome. At least for inshore and coastal daysailing. Of course, offshore, long-haul is a different story. I think the proa is a craft of a particular context, a situational solution.
@proasisproject7 ай бұрын
Absolutely agree with your last sentence. A proa is definitely not the best design for inland sailing. That said, we only do inland sailing over here, the Baltic sea is just not a real ocean. We've logged well over 1000 nm with Proasis, considerable stretches singlehanded. Believe it or not, shunting our canoe is really as easy as the soothing voice tells you :D If you are still not convinced you are very welcome to join us sailing and see for yourself. But be warned, the girl with the soothing voice might join too 😅

how do the rudders behave if you run aground? will it slide up or kick up? It looks like if the rudder kicks up (say by sailing into a sandy bottom) it would still provide some steerage, which is ideal rudder behavior in my opinion
@proasisproject9 ай бұрын
Both (kind of). The foils themselves (old F18 daggerboards) run in casetts up and down. They can be adjusted for the water depth or even completely retracted. The connector tube has a fuse which allows it to telescope and kick up the rudder so far that they clear the surface, even if all the way down. The fuse is reset by simply pushing down the rudder frame. It snaps back automatically. The entire setup consists only of two tubes, a round piece of PVC and a bungee cord. No metal or complicated mechanic. So the draught of the rudder can be preset. If something goes wrong (shallow spot, rock, reef or heavy floating object) they kick up.
@dominictarrsailing9 ай бұрын
so is the fuse a notch that the bungee grips? so it pops out and is then free?
@proasisproject9 ай бұрын
@@dominictarrsailingno it's never free. There is a smaller tube inside of the yellow one. Both tubes have a semi circular cutout. The cutouts are lined up by a PVC cam which is tensioned by bungee cord. If the rudder hits something the inner tube is pulled out about 30cm to kick the rudder up. Sounds complicated but it's as simple as it gets. Don't worry if my explanation is difficult to follow, there will soon be a video showing that part in detail 😅

Love the linked rudder design. Question: Is there a reason the leeboard is on the vaka and not the ama? My understanding is that typically the leeboards are on amas on shunting proas to make it easier to keep the ama to windward. Is this a non-issue in the proasis design?
@proasisproject9 ай бұрын
Thanks! No, the placement of the lateral plan (leeboard, foil, hull shape or whatever) on the windward hull is the exception. It's mainly promoted by designers with a western background, there is no traditional design with this feature. The reason is that the lateral plan on the windward hull puts a lot of bending moment on the entire structure, in fact really counteracting the design idea of a proa. Proasis has no problems with getting caught aback whatsoever. In the last 3 years it only happened once in zero wind because of a 180° shift. Most of the time the reason for getting caught aback is either an imbalanced design of lateral and sail plan or wrong handling. As pointed out in the video it's important to work with the wind, swell and canoe instead of fighting the elements by applying force.

It's a bit scary to me that there are no other stays and not even a halyard or brailing lines, that's because this is the racing style, right? would hate to drop the sail in the water during the shunt but it could make for some exciting changes of place when racing!
@proasisproject10 ай бұрын
The shunt is actually not a particular good one because the tip of the sail didn't really fit to the canoe and we had to improvise, resulting in a lot of tying. Same for the steering paddle, I set it up in a wrong way so we had to deal with it on the water. I kept at least one shunt in to show the great boat handling needed to sail these canoes. Performing the maneuver without the stays requires a lot of practice, especially with a large and heavy sail in strong wind. If anything goes wrong and the shunt is not in perfect harmony with the motion of the canoe the sail drops. It feels almost like a dance if performed more fluent and beautifully than shown in the video. When the good guys go racing they hardly drop the sail, so its not really a thing :D
@pakde800210 ай бұрын
On sailboats in Bali the setup is really simple as with other traditionally rigged crab claw sails. Some don't even have anything tied to the sail at the bow, just a basic forked stick type arrangement so shunting happens really fast, basically the amount of time it takes to walk from one end to the other and back again with the rudder paddle. And those balinese boats are crazy fast. Google Balinese jukung race.

Using the same amount of material, you can build a proa with a longer waterline than a cat, which makes it both faster and more seaworthy. So it's lighter than a cat with the same WL, which means it doesn't need as much sail area, which means the rig can be smaller, making it lighter again! the comparison with a trimaran is even more favorable. The disadvantage is that hulls cannot be optimized for the direction they travel, they are just long and skinny same at both ends, and also the complexity of the shunting system. but my favorite advantage is that you are sailing a floating conversation piece that's very unusual, unless you are from a small atoll in the pacific!
