There’s an old German saying, “If at first you cannot boat, boat and boat again. That is, two hulls are better than one.” The saying, origins unknown, applies almost too perfectly to the experience of wersy on Thingiverse. When wersy designed, printed and tested out his remote controlled motor boat, he found that his high powered plane out-runner motor was too strong. And, so, he added an extra hull.
You can see the designs for wersy’s first iteration here, and in the video above. Running on an out-runner motor for an RC plane, the boat continually capsized when the throttle was pushed too far. While some may be impressed by the design of the 3D printed RC boat, others will marvel at the doggy that barks at it without cessation.
To improve the design, wersy went for a hydrofoil design, based on the hydrofoil specs for a typical sailboat. Still, wersy found problems with the RC ship, unable to achieve an optimum balance between the pitch of the boat’s wings and the drive of the throttle. The little fella couldn’t seem to swim smoothly.
Finally, the designer settled on a boat with two hulls, which could fully take advantage of the RC motor’s power. For those thinking of building one at home, you’ll need a strong motor, like wersy’s. His dual-hull design has the least chance of capsizing of all of his designs and looks sweet, to boot. But, if you’re new to constructing RC vehicles, wersy recommends that you start with something simpler, as the dual-hull ship is still experimental and the impeller can be dangerous running at high speeds. Watch the experimental boat below!
