1. A hot tub cover hoist mechanism comprising:
an overhead mechanism configured to attach to a ceiling structure above a hot tub and comprising housings with shafts comprising at least a first housing and a second housing with the first housing comprising a first shaft with a first end region and a second end region, and the second housing comprising a second shaft with a first end region end and a second end region;
a system of cables comprising cables that comprise at least four cables with first cable ends and second cable ends where each cable comprises a body that extends vertically downward, and the four cables comprise (1) a first cable having the first cable end attached to the first end region of the first shaft and the second cable end attached to a rigid cover, (2) a second cable having the first cable end attached to the second end region of the first shaft and the second cable end attached to the rigid cover, (3) a third cable having the first cable end attached to the first end region of the second shaft and the second cable end attached to the rigid cover, and (4) a fourth cable having the first cable end attached to the second end region of the second shaft and the second cable end attached the rigid cover;
a lifting mechanism within the overhead mechanism comprising a direct drive lift in communication with at least the first shaft and the second shaft and the direct drive lift (1) is in communication with the first cable ends, (2) is configured to exert a vertical first force through the cables, and (3) is configured to turn the first shaft and the second shaft to rotate the first shaft and the second shaft in a first direction and a second direction in synchronized movement to lift and lower the second ends in unison;
the rigid cover having a weight with a vertical second force that is not more than the vertical first force from the direct drive lift through the cables, in communication with the second ends of the cables, and comprising (1) a first edge with a first end region attached to the second cable end of the first cable and a second end region attached to the second cable end of the second cable and (2) a second edge parallel to the first edge and with a first end region attached to the second cable end of the third cable and a second end region attached to the second cable end of the fourth cable that are configured to distribute the weight and the vertical second force of the rigid cover equally when the cables are under tension; and
a cable-tensioning mechanism attached to each cable and configured to maintain each cable under tension when the rigid hot tub cover is resting on the hot tub.
