What's Included in the Plans
Full-Scale Plot Templates
Forget time-consuming measurements. The plans come with 1:1 full-scale plots, printable on any A4 printer. Simply tape the sheets together, align the codes, and trace the shapes onto your chosen material. With no guesswork, you'll be cutting and assembling in no time.
Build Options for Every Maker
- Basic Plans: Ideal for hand-cutting your parts with a sharp knife or blade.
- CNC & 3D Printer Files: For makers with access to CNC machines or 3D printers, the plans include STL files for components like the rudder and daggerboard and DXF files for cutting plywood parts.
Clear Build Instructions
From detailed assembly notes to material lists, the plans provide everything you need to get started. You'll even find creative tips for using tools like a serrated knife for cardboard and hot glue for rapid assembly.







After 3 hours
this is what I ended up with. Still lots more to do, but it was quick to cut out and glue together. Cardboard is a great material, it's structural, it's everywhere, and it's free!
There are plenty of notes with the drawings and in the build notes, to get you started. Also a material list of the major materials you need (not much) to build. With a coat of outdoor paint she will soon be ready to sail.

Simple Assembly, Stunning Results
Cardboard or Plywood—Your Choice
Cardboard is surprisingly strong, easy to source, and free! In just three hours, you can have a fully assembled hull, ready for the finishing touches. If you prefer something more durable, use plywood for a longer-lasting build.
Remote Control Capable
Take your Geelong 850 to the next level with remote control functionality. The tiller design is optimized for RC steering, and the plans include everything you need to integrate a simple servo setup.
Daggerboard Design
Just like my larger boats, the Geelong 850 features a high-performance daggerboard. Whether you craft it from plywood or 3D print it using the included STL file, this essential addition ensures your model performs exceptionally well upwind and downwind.






Steering
The Geelong model includes a simple and effective rudder setup for precise steering. If you have access to a 3D printer, the plans include a rudder design that integrates seamlessly. The assembly uses a sturdy shaft with bearings and a protective housing to keep water out, ensuring smooth operation.
For those without a 3D printer, alternative materials like plastic tubing or straws can be adapted to create a functional steering mechanism. With basic tools and creative problem-solving, you'll have a reliable rudder system ready to guide your model effortlessly.
