RC Boat
DESIGN OBJECTIVE: I will DESIGN and CREATE a RC high-performance powerboat with a classic V-bottom hull or a “Cigarette boat”. My initial thoughts are a modern take on a classic v-bottom cigarette boat. My plan is to use a RC outboard motor which will drive my design, but may change as my research unfolds. The boat model will be 18-24" in length. (10/27)
I was inspired by a jet speed boat design and have changed my design. (11/15)
Long Cigarette Body Design
Covered Cabin
Single Outboard Engine.
*I also want to keep in mind how I will be assembling the boat and do not want to keep the design too complicated.
10/27: Initial Plan Outline/Schedule
Here is a list of the things that I think I will need to know or do.
Get Inspired by other speed boat designs
Breakdown what designs I like and what is feasible
Explore the anatomy of a boat.
Create thumbnails of possible designs
Further develop and explore 2-3 thumbnail designs
Finalize a concept design
Make a simple 3d model the boat
Finalize the 3d model design
Slice up the design to create ribs and keel structure.
Create additional structural supports
Prepare the parts for laser cutting and cut out parts
Assemble hull frame
Prepare model for cutting boat shell and cut out shell
Attach/glue shell to boat frame.
Prepare boat for water test- sand edges and seal hull
Perform a water test. May need to add weight in boat?
Write a reflection and evaluation of the the boat design.
Focused Resources 10/6
How to design a stable high-speed boat was a very good resource for design the front chine of the boat and how it displaces water.
This was a good intro video on the types of hulls.
This video gave me an idea of rc boat construction.

An Introduction website on making RC Boats
Just found this . . . Very Cool!
11/2: Personal Speed Boat Inspiration Board
Some of these boat designs are really cool, I particularly like the cigarette style boats.
11/4: Exploring and Defining My Boat Characteristics.
I annotated my inspiration board noting what designs would be good for this project.
11/5: Thumbnail Sketching Boat Design Tops
I used Krita (Free) with symmetry active to play with possible boat shapes from the top view. After drawing an initial design, I cut and pasted the shape and edited it with the eraser. Then repeated.
The chine or lower portion of the boat is very standard, but I will explore possible designs as well.
I feel that I need to spend a few more sessions playing with more designs.
***I think I need more sketches . . . I only explored one basic hull shape
11/7: 3D Sketching Designs
Playing with potential designs in Maya. These are quick models. I started with the initial top view, duplicated it and played with different forms. I used booleans to subtract the back section.
Top View: I really lo like the far right design.
Front View: Here is the front view showing a portion of the chine. I like the far right model.
11/14: Total Direction change - From Outboard Motor to Internal Jet Power
I watched a video showing how this guy designed a 3D printed RC Jet Boat. I thought it was super cool and it really got me thinking how it could be integrated in a custom boat.
This is a video of a 3d printed RC boat water jet propulsion design test
I found a RC boat water jet propulsion design that I can print an integrate in my own design. Super excited about this find.
11/14: Imported the RC Boat Water Jet Propulsion Design
I imported the Jet Propulsion Design in Maya and rigged it to test on the rudder nozzle turn radius.
11/15: Integrated Jet Propulsion System With My Boat Model
I tested to see how well I can integrate this jet propulsion system with one of my designs. And I have to say that it went fast and super smoothly. I am even more excited.
11/16: Side Direction - Boat Model Hull Prototype.
Took a break from the propulsion system and focused a bit on the hull shell prototype. It was also very easy and went smoothly.
Testing it out helped with my over all design and how it should be built.
*I decided to cut off the tip and 3d Print it instead.
