I would like to create a RC tugboat similar to this one to carry my kayak around but using cheap PVC tubes and a pair of BlueRobotics T200...
An update to the thread, I'm almost done with the hull, I will soon publish some pictures. The result is pretty nice, but I am left to design the...
At the local Maker Faire I’ve seen a very interesting concept for a high performance keel with integrated propeller in the bulb. The keel is...
What about thickness?
Back here, the main hull is finished, now I'm thinking about the keel. Considering the 1.5m final size, the keel will be 38x25cm, simple, no NACA...
I see your point, interestingly sail buoy managed to survive for almost three months while being remotely controlled. The boat could try to avoid...
I'm actually using part of their code, it is very detailed. Just to mention a small example, every 5s the controller checks wind direction and...
Haha well depends which city you go to. I asked the A-Tirma boat designers for some more detailed hull measures, I'll try to determine how many...
I don’t have any limit for the boat propeller size, but considering the LoA will be between 1.3 and 1.5m there’s an obvious limit to its size....
SeaCharger used an anti-vegetative paint to avoid barnacles and other sea life to grow on the hull; there should also be non-polluting...
I can think of extra drag, but I will make the keel detachable for an easier storage; then it will be fully solid without any air inside. What...
I know, but I am now moving towards a mixed wingsail+motor solution. The A-Tirma looks great but unfortunately their design is not open source...
Won't s Kort nozzle get easily tangled with seaweed? If I make a the keel empty and let the water flood it to save on weight?
Advancements on small sailboats are mostly bond to wingsails. A very interesting hull shape, which interestingly resembles a shark, is the A-Tirma...
Yeah I plan to make the wingsail with Oracover transparent film, similar to (cheap) balsa RC plane wings. For the flexibility of the sail I don't...
No I will use a belt for the first tests then move to a proper gearbox.
Haha good reference. Now I'm following calculations on this paper in order to dimension the main wing properly. Are RC sailboat hulls able to...
I've come to the conclusion that having a small wing-sail is necessary. I will still cover the hull with mono crystalline solar cells but I will...
Bluebell I have a colleague who makes VAWTs with adjustable pitch and can lend me one of their prototypes, 50W at max, three-bladed and 60cm,...
What's your suggestion in that case? I've been in the open sea in several occasions and experienced winds up to 7 on the Beaufort scale, that's...
