ABSTRACT:
The watercraft dry storage assembly includes a cylindrical port bladder and a cylindrical starboard bladder. Both bladders are made from sheet material with a substantially non-stretchable polyester or nylon scrim encased in a poly vinyl chloride plastic, a urethane plastic or a mixture of poly-vinyl chloride and urethane. The bladders are attached to each other. A blower system blows air into the bladders to lift a boat hull out of the water. The blower system also sucks air out of the bladders to lower the boat into the water. A guide system indicates the location of the bladders under the water and guides the bladders as they are inflated. One or more envelopes with open tops are attached to the bladders if required and receive rudders, keels and propellers as they are raised by the bladders. After the open tops are raised above the water, water in the envelopes are pumped out by a pump.
