Abstract
A boat lift mounted on a plurality of spaced masts secured in suitable foundations are provided to support an equal number of spaced rails extending angularly into the water to a depth below the draft of the boats to be elevated on the boat lift. A plurality of boat carriers slidably mounted on the rails have spaced rollers engaging the flanges of the rails to facilitate movement of the boat carriers relative to the rails. The boat carriers have horizontally extending extensions secured to their lower ends to underlie the boat which is chocked to hold it in an upright position on the boat carrier extensions as the boat is moved out of the water. A winch housing having a power actuated winch therein is provided to wind up a cable secured to the boat carrier to pull each of the carriers and the boat on the carrier extensions up the rails to elevate the boat out of the water. In boat lifts as heretofore constructed the cables extended over the top of the rails and down the front of the rails to engage the ends of the boat carriers to pull them up above the rails. These exposed cables posed a dangerous condition for anyone standing in the area of the boat lift, because if a cable broke it would fly with a terrific force, and if the cable struck anyone it would inflect very serious injury. With my improved boat lift I have succeeded in connecting the cables from the winches to the boat carriers beneath the rails, and therefore if a cable breaks the parties standing in the area of the boat lift are protected because the cable mechanism is nested beneath the top of the masts and the lower sides of the rails and therefore the cables are prevented from flying in an uncontrolled manner.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
