Bottom washer

So...Useless idea #3738 marinas should install boat bottom cleaning systems like car wash brushes except for the bottom of boats. This would keep down the slime on boat bottoms and also prevent hard growth if done every now and then in places without severe fouling. I imagine some sort of brush system that scrubs your boat bottom like car wash brushes do. What could they charge for such a service? I have already published, and bequeathed to the public, my idea to eliminate all bottom growth resulting from 'parking' the boat. A 'water garage' consists of a plastic bag in the water, possibly floated with pop bottles, which you draw around the boat when parking it. One section is allowed to sink, so the bag may be drawn under and around the boat and then raised to the surface to completely surround the vessel. A pump in the boat draws out the water inside the bag until the hull is dry, except for those areas such as fixed propellors or rudders which cannot be lifted out of the water. 'doghouses' could be devised to surround such areas, guided into place with lines. Small smooth hulled vessels are easiest to protect using this idea. A medium sized rock inside the bag attached to a hose pickup will sink, forming a sump and keeping the pumpout hose pickup under the deepest part of the boat. Since the water would not need to be lifted, large capacity, low head pumps, even possibly a *PWC, could be used to pump out the water. Treated wash water, or an anti growth compound, or a solution tailored to dissolve only barnacle shells and zebra mussel shells could even be introduced into the bag once pumped dry, and recovered and recycled before departure, possibly stored in the mooring float, if it is made from an oil drum, whatever. Perhaps it would even be possible to concoct some paint that could be introduced, possibly attracted to the hull material with an electrostatic device, so as to chemically bond to the hull? If it did not adhere to the bag material, bottom painting might become very easy, and the true waterline would be automatically painted on the hull in calm water. To depart, a little water is introduced back into the bag, the gate is lowered, the floatation boom manoueverd to one end of the boat, the doghouse, if needed, removed, and the vessel departs. All fouling due to being moored is eliminated, since the hull remains dry while the bag is pumped out, and all water dependant growth and electrolytic galvanic corrosion ceases once ''parked' in the 'garage.' This idea could be used at the dock or at anchor. It is particularily attractive for 'weekend' type boats, especially I/O's, outboards and centerboarders. Furthermore, bilge pumping becomes uneccessary so long as the bag is intact and the floatation boom is tall enough. It could be raised above it's floatation level with lanyards, high enough to keep most waves out of the bag. It would work best in calm anchorages, and could be kept pumped dry during heavy weather episodes with smart standby pumps. Rain water might be welcome if it flows into the bag from on deck. Salinity sensors could be used to trigger standby pumps. What type of plasic film would be best for the bag? Is there a material that would sink, or be neutrally bouyant, or would ballast weights be required in addition to the 'sump weight?' *Incidentally, why not use a PWC jet pump in the PWC, in the water, connected to a fire hose to fight fire or provide irrigation on or near the shore? The PWC might need to be restrained, but the water ejected from the pump could probably be squirted high above a road beside a shoreline, and could land in an area where it might be pumped further, to croplands, etc, obviating the need to pipe water under a roadway. The hose connector fitting on the pump exhaust could be a quick disconnect wing nut setscrew or even a threaded connection. Talk about smoke jumping! A floatable para wing would enable easy launch from a ferry aircraft such as a C130, and could provide a safe controllable landing on a lake or river near a fire, etc. Two or three could be dropped, and one used to retrieve fuel drops and other supplies while the remainder pump water. A 70 horse pwc could move a lot of water! Long lengths of polypropelene fire hose could be dropped and recovered for use if it floated. -- Terry K - My email address is MY PROPERTY, and is protected by copyright legislation.
