This project established the most suitable potential design for a fully renewable energy powered boat that requires minimal to no stationary charging. The variations of battery being assessed were a standard lead-acid, absorbent glass mat (AGM), and lithium-ion batteries. The motors assessed were outboard and inboard motors, as well as whether or not to be voltage regulated. The power sources assessed were tidal, current, wave, and VAHT power. I After examining and assessing a variety of batteries, motors, and hydro kinetic technologies, a final design could be created. It was determined the best options was an AGM battery (due to the rapid charge time and compatibility with battery management systems), a voltage unregulated outboard motor (due to the use of alternate current), and a tidal power/VAHT hybrid technology was the best-suited. The innovative power generation design utilized a bi-rotation VAHT system with a blade diameter of twenty-two centimetres, attached to a steel shaft. This shaft was attached to the main mechanism by steel filaments, which were suspended and stabilized by four neodymium magnets. This shaft could be released or withdrawn by inducing a spool of the steel filament. Once the technology was entirely within the cavity, the same technology used to monitor the lower shaft, would seal the cavity.
