## Abstract

A boat-mounted wind power assembly for powering devices of a boat includes a first shaft that is rotatably coupled to and extends vertically from a boat. A plurality of blades is coupled to and extends from the first shaft. A generator is operationally coupled to the first shaft. A rectifier is operationally coupled the generator. A battery, which is rechargeable, is operationally coupled to the rectifier. The battery is selectively couplable to devices of the boat. The blades are configured to convert kinetic energy of wind into rotation of the first shaft. The generator is positioned to convert rotation of the first shaft into unstable alternating current. The rectifier is positioned to convert the unstable alternating current from the generator to direct current so that the battery is charged by the generator. The battery is configured to supply direct current to power the devices of the boat.

## Claims

### Claim 1
