A BOLD ATTEMPT - The Voyager did not make it as far as the Scout, but the basics of the mechanical design were sound. In theory the boat should not have sunk, but it is impossible to predict events

The project was started by Isaac Penny and Christopher Sam Soon in the year 2013, for the sole purpose of achieving a daring task: Building an autonomous boat from scratch that would be able to cross the earth's ocean. Both of them spent their spare time from work to craft the boat. Christopher being an electronics/firmware engineer, handled the electronics and software aspects of the project while Isaac, a mechanical engineer, worked diligently on the mechanical design. Over the course of the project, a significant amount of help and assistance was provided in the mechanical build of the boat. In particular, we would like to extend our sincere gratitude to a talented and dedicated tradesman, Randy, who provided his skills, dedication, and effort towards the realisation of the project. Lastly, we would also like to extend our appreciation to David Penny, Isaac's father, who has provided much needed infrastructural support and advice for this project.

MAYFLOWER: This is a boat built by a consortium of suppliers and academics in 2020, with backing from IBM. The idea is to complete a transatlantic voyage without any humans onboard. Being larger than the Scout and Voyager, we think she stands a fair chance. We will be reporting on progress in 2021.

The current energy autonomous (solar powered) transatlantic record holder is the Tûranor PlanetSolar, seen below. Note, this boat was manned, not crewless. Nevertheless, with an autopilot and collision avoidance sensors, in our view, she would easily make it across the Atlantic Ocean - from one waypoint to another.
