Abstract: A water spray device for cleaning the hull of a boat is disclosed. The spray device includes a handle and wand portion. The handle portion has an angled portion separating an upper and lower part, a channel formed through the handle and a top and bottom open end. The top end engages a hose connected to a water source. A shut-off valve is disposed within the handle channel proximal to the top end. The wand portion is an elongated tube having an channel formed therein, an open top end for engaging the handle bottom end, a closed bottom end and a plurality of spray nozzles disposed along the wand. Water enters the handle portion, flows into the wand portion and out the spray nozzles. A user of the novel water spray device simply positions the spray nozzles towards the boat hull from the deck of the boat while holding the spray device and walks around the perimeter of the boat to quickly, easily and thoroughly clean the boat hull.
