Abstract
A positive drive boat lift apparatus includes a support structure located proximate a body of water. There is an elongate threaded shaft disposed adjacent to the support structure and extending in a substantially vertical direction. A nut threadably engages the shaft. There is a boat accommodating platform and one of the shaft and the nut are attached to the platform. The other of the shaft and the nut are rotatably mounted to the support structure. The shaft and the nut are rotated relative to one another in a first direction to raise the shaft relative to the nut and in an opposite second direction to lower the shaft relative to the nut, whereby the platform and a boat accommodated thereon are selectively lifted and lowered relative to the body of water.
