What is CAD? CAD (Computer-Aided Design) is a technology used to create precise drawings or technical illustrations of physical objects. It is widely employed in engineering, product design, and architecture to produce 2D and 3D models.
For this project, I am using SolidWorks. This work highlights Design for Assembly and also Design for Manufacturing.
Overall assembly of the Hydrofoil Tow Boogie.
Our hydrofoil tow boogie project requires a series of parts to be designed. This page focuses on two key components:
The Main Boogie Board, which serves as the structural floating boat core.
The Fuselage Attachment Mechanism, which connects the motor to the board securely.
Tow Boogie Board Design
Design Choices: The main board is the central structure of the tow boogie, composed of three layers: two of plywood and one of foam. The foam is carved to allow cables to run between the battery and the ESC controller/electronics box. This modular choice improves repairability, weight distribution, and prevents part movement.
Motor pod depth: 20 cm from the base plate to the center of the motor pod.
Motor distance from rear: Half the board length, adjusted for planing stability.
Tow point placement: Positioned 250 cm from the motor for optimal control.
The overall shape takes inspiration from boogie boards, commonly used by DIYers, but it is adapted to fit within the foam body dimensions of 20ft x 40ft x 2in.
Design Choices: The motor attachment mechanism ensures the motor is mounted at the correct depth and securely attached to the board. Key features include:
Cables threaded internally for a clean and safe design.
An aerodynamic shape to minimize drag while maintaining strength.
Sturdy construction to handle the forces and vibrations during operation.
