Lift for water entry/exit and methods of manufacture and use thereof

A method for mechanically lowering a person into and out from a water-containing structure having a usable maintained water level, an exterior deck, and an interior vertical wall surrounding a volume of water having a waterline at the usable maintained level, the method which comprises:

• configuring a waterproof lift with:
• an upper portion comprising a lifting beam defining a rotation axis;
• a seat assembly:
• comprising a chair having a bottom seat surface;
• and
• being attached to the lifting beam in a rotatable manner about the rotation axis to permit movement of the chair between a wet position facing an interior of the volume of water and a dry position facing the deck;
• and
• a waterproof drive assembly configured to move at least a portion of the lifting beam between a lowered state and a raised state;
• connecting the waterproof lift to a waterproof base housing having an upper surface such that:
• in the lowered state, the lifting beam is at least partially contained within the base housing;
• and
• in the raised state, at least a portion of the lifting beam is above the upper surface of the base housing at a given height;
• fixing the base housing to an interior wall of the water-containing structure at a level to place the upper surface of the base housing below the waterline of the water-containing structure such that:
• in the lowered state, the lifting beam and the seat assembly are completely submerged in the water;
• and
• in the raised state, the bottom seat surface of the chair is above the waterline and above the exterior deck sufficient to permit a person to sit upon the chair.
