How do you plan to lift the mast? If you don’t have a tabernacle (hinged mast step) you will have to lift the mast about 1 ¼ inch to get it off the step and then you will have no way to control the lowering f the mast. The mast was stepped on my boat by the previous owner by using the halyards of two other boats tied up alongside to lift the mast. I used a boom truck to un-step the mast when I hauled my boat.
Do NOT try to lower you mast by hand. You will get hurt and destroy stuff.
The picture is of the step mounted on a prototype of the tabernacle I am building. I am using ½ inch aluminum for the tabernacle.
