Remote-Controlled Boat for eSMART Competition (2020)
Design and development of a high-speed RC boat with comprehensive hydrodynamic analysis.
Project Overview
From February 2020 to June 2020, I participated in the eSMART Competition where we designed and built a remote-controlled boat optimized for maximum speed in actual sea-water conditions. The project involved comprehensive hydrodynamic analysis, stability calculations, and validation through both computational and physical testing.
The remote-controlled boat design for eSMART Competition.
Technical Analysis and Development
Key Contributions:
- Conducted static stability analysis by calculating the boat’s metacentric height
- Developed Python-based simulation tools for performance prediction
- Performed comprehensive drag calculations using the Guldhammer & Harvald method
- Implemented thrust calculations using KT-J and Kq-J Charts for Wageningen B-Series Propeller
- Validated design through two-phase CFD simulations and physical experiments
Performance Simulation
We developed a comprehensive simulator that integrated various hydrodynamic calculations to predict the acceleration, velocity, distance covered in water.

Sea water testing of the RC boat design.
New Design
This is the new design of the RC boat. It has a more streamlined shape and a larger aspect ratio for smaller resistance.
