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.

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.
