Up until now, boats with dirty hulls needed to be hauled or cleaned by divers—both expensive propositions at over $3 per foot in many areas. With the new Davis Scrubbis Underwater Hull Cleaning Kit from Davis Instruments, one person can easily remove algae, marine life and waterline scum from almost any houseboat while standing on the dock or deck, or even seated in a dinghy. With a clean hull, the boat will be up to 30% faster and offer as much as a 20% fuel savings—it's a marine product that actually pays its owner back. Davis is introducing the product at IBEX, Oct. 2–4, Tampa, Florida, booth 1520.

The magic of the Davis Scrubbis system is its unique buoyant cleaning head. Once pushed down the side of the hull, its 4.4 lbs. of flotation lifts it back up. Since it doesn't need undue pressure or rapid back-and-forth motion, it's not a backbreaking chore. A video is at bit.ly/scrubbis.

Designed for fresh or saltwater, the 5" dia. x 16" wide Davis Scrubbis cleaning head is made of a durable foam-like material, so it won't remove toxic and expensive antifouling paint. Soft cleaning fins take care of most accumulation. For stubborn areas, the head can be flipped to reveal a stiffer fin.

With its 43"–86" telescoping aluminum handle and 43" extension tube added, Davis Scrubbis has an impressive 12' reach. Attach the angled end section and it easily cleans most remote underwater parts of the hull. Strakes, steps, keels, rudders, and around thru-hulls and other fittings are no match for the innovative device.

Davis Scrubbis will clean a 30' boat in 20 minutes. Best results are achieved using it once or twice a month, in conjunction with a hard antifouling paint.

For hulls that need most robust cleaning, optional attachments make the job even easier. Groovy Scrubbis' bristles remove barnacles, worm casings and other tenacious organisms. The Waterline Brush features soft cleaning fins on one side and a replaceable scrubbing pad on the other. It's perfect for waterline scum and stains.
