One more airboat


Finally, May have come. I think to test the ekranoplan this month. To do this, I need several things to coincide. I need a van on which I will transport the boat, but I seem to have agreed on it. Good weather is needed where I will conduct tests and the help of several people, preferably with a boat equipped with a motor. All this stuff need to be organized.

Since the ekranoplan has been packed for a long time and is waiting for its time, moreover, there has come universal quarantine because of which I lost my job, but I did not lose access to the workshop, so I managed to construct another small airlock, a copy of the first so that I could ride together race. Today I already pasted it with fiberglass. It remains to paint and build a mount for the motor.

Another thought haunts me. I would like to install a fiberglass cabin left over from a paratrike and install it on a boat and put the engine on the front like on an airplane. I set everything until it was screwed down, sat inside and it seemed to me that this is very cool. If I still decide to do this, then we get a super boat, outwardly somewhat similar to the air boats of the era of the 30s participating in the legendary raid Pavia – Venice. I am inspired by that era and those cars. For a complete buzz you had to get a leather helmet. I sewed it from a piece of leather that I have. Still need glasses and a white scarf, developing at the back. I don’t know how stable the boat will be in water in such a layout, but it will look great and the thrill of riding will be cool. It remains to be decided which steering wheel to install – air or underwater. Both options have pros and cons, you need to think. Below is a photo of the work done.

Airboat tests in wind and waves


Today I tested a boat on a big wave. I went to another lake closer to home. A strong wind rose and I decided to test the stability of the boat to the wave and wind. Initially, there were problems with the engine, he is already a veteran, so I had to conjure a little and eventually it all worked. I’m a small backwater and it seems that the wave is small because that ripple that seems a little further but when I left closer to the middle of the lake I was met thirty centimeter waves. The boat went against the wind and fought with the wave. Against the wind, I accelerated to 25 and then the wave started to turn around and met me aboard, but the boat was surprisingly well able to hold the blows, it jumped from wave to wave and didn’t even splash too much. In the opposite direction I gave full gas. Forty-one scored instantly, but the shaking was unrealistic. To be honest, on such a rodeo the gas did not turn off too much and shook and shaken. Nevertheless, the boat was controlled and there were no prerequisites for capsizing. This was my second time on this boat, and under such conditions the water surface I felt completely safe, but I worked with gas cautiously and I only had full gas accelerated against the wind and, having gained some speed, I already cleaned the gas. Unfortunately, it was not possible to remove a lot from the cabin because of the shaking. Only my friend Karlis took me off his phone and for about a minute, the video will be from this test. Thank you very much to Karlis for help in these trials. Yes, and more from the shaking or old age exhaust pipe to the muffler broke. He was alert before and could not stand the vibration. In general, it broke down and the tests ended there. Need to order a new part. In general, I am satisfied with the tests. The boat keeps the shock wave well controlled and accelerates the wave. The motor is a bit weak in still weather, still ok against the wind. I think for the following tests to make a small fairing in front and remove the protection of the screw, it brakes the boat a little. You can try to measure the full speed with these changes. In the meantime, I will do something else until the item arrives. below the photo and a short video.

p.s. The most amazing thing is that during the test I forgot to put a small oar in the cockpit of my boat and put it on the deck where it was safely and rolled during all my jumps and shakes, and did not fall. I safely used it after raking up to the shore.

First airboat tests


Yesterday, on the 12th of May, I tested my airboat. For the first time it happened in my life that not one fear was not confirmed, but all hopes were fulfilled. The boat turned out to be very stable, very maneuverable, very fast, considering that it has a 10 kW motor. His thrust is about 45 kg, which means that all my work was not in vain and the cross-flow on the boat’s hull does its work – reduces the wet space of the bottom of the boat, this leads to the fact that the boat is already on the floor of the gas going to the hydroplane. Unfortunately, my GPS broke down and I could not find out the speed. According to my feelings and the feelings of my friend who has a lot of experience walking on motorboats, my airboat is about 40-50 km per hour. On the water is a lot. I didn’t even expect such a result, but to be honest at some points I personally felt that speed was over 50 km per hour. And this is the smallest paramotor engine that is. I can imagine what will happen if you put the motor on the boat at least 20 HP. The speed will increase significantly. Of course there may be various problems with increasing speed, but at the moment the boat behaves well with this motor. I also did not weigh the boat, I think it weighs around 40 kg. This is a bit much. But I deliberately over-tightened it trying to make it very durable. Therefore, the next boat can be made a little easier, because now I know where you can remove the excess. In general, I am very pleased and eager to take the boat to any river. Now need to wait until the summer weather settles and you can continue to test the boat. As always below, I attach photos with the latest events and attach the video I took on the phone and quickly assembled it. I think in the future to approach the process of filming more responsibly and get an Action Camera. And I also wanted to say a big thank you to my old friend Oscar, who sheltered my boat on his territory in his spacious garage and helped me with the water tests! For this, I am very grateful to him without his help, I would have had difficulty.

And here is the video
