A high speed, reduced clearance lift has a lift platform that is raised and lowered by operation of a telescoping hydraulic ram that has at least three telescoping sections, such that, the retracted height of the telescoping hydraulic ram is minimized while the deployed height of the telescoping hydraulic ram is such that the lift platform is lifted the height needed to, for example, lift a device out of the hull of a watercraft. To better stabilize the lift platform both in the retracted and deployed positions, locks, preferably in the form of actuated locking pins, interface with receivers mounted in a frame in which the lift platform travels. In such, when the locking pins are extended into the receivers, the lift platform and any payload resting on the lift platform are held steady without the need for hydraulic pressure.
