I've designed a 3d printable hydroplane that can be launched across a pond or lake with rocket engines, and you can print it with this kit.

I originally made two versions of this three-point hydroplane boat, which is similar in principle to Donald Campbell's Bluebird K7: a smaller version featured in this video, and a larger one, in this video, that hit approximately 60mph (before taking off!). This 3d printable kit is for the larger version, although it has been since redesigned to be more easily printed, stronger, and simple to set up for a run!

This large multi-part kit provides you with the required information and files to print, assemble and launch a huge rocket-powered hydroplane. Included among the print files is an assortment of motor mounts allowing various launch options, and a blank motor mount allowing adaptation to fit with any motor size available.

Here's a link to where to get rocket motors.

I’ve been taking my 3D printed rocket boat to the next level through scaling it up and adding more engines! With the success of my micro hydroplanes, the natural succession was to do more testing.

Read More About This Project

I scaled up the boat on CAD and got to work printing out all the parts I needed. This boat is twice the size of the previous boats I was playing around with last month which should help with stability when going over small ripples and waves at high speeds....
