Hammerhead sharks have sort of like fins on the sides of their heads. The eyes are out on the end of them. But their heads are still streamlined if you look at them from the front. They are like streamlined stalks or wings. It's sorta like having an extra set of fins like porpoises have on their sides where the arms used to be before they went back into the sea and evolved. But hammerheads have them on their heads. Cheers, Ellen Shark skin saves naval industry money Covering ship hulls with artificial shark skin could help ships sailing smoothly. The growth of marine organisms such as barnacles on ship hulls is a major cause of increased energy costs in the naval industry. Shark skin offers a structural design that prevents this so called 'bio-fouling'. Ralph Liedert from the University of Applied Sciences, Bremen, Germany, is presenting his work on the application of artificial shark skin in a new anti-fouling strategy at the Society for Experimental Biology Annual Main Meeting in Barcelona [session A7.66]. Shark skin comprises scales that can flex individually from each other. Liedert produced a synthetic shark skin of elastic silicone, which has a significantly decreased contact surface. This reduced contact surface makes it harder for barnacles to attach, and reduces fouling by 67%. When applied to the ship hull, this artificial surface enables ships to ´self-clean´, and a speed of 4-5 knots would remove all organisms attached with little adhesion. Until recently, paints containing a biocide were used to prevent growth on submerged surfaces, but these were banned because of the the toxic effect of the highly toxic and unspecific biocide component on marine life. As barnacles, mussels and algae cause up to 15% increase in the drag resistence of ships, this research is providing an alternative anti-fouling strategy of great importance. Joe Now that's interesting. I wonder if a shark-skin suit will people off my back? -- jlrogers±³© |

You really should attribute things like this; otherwise its just plagiarism. http://www.scienceagogo.com/news/200...runc_sys.shtml Nahh, you will find the link and post it for me.. Joe |

Duh! That's a lie. You can still buy anti-fouling paint around here. They have biocides in them. Cheers, Ellen |

Too bad ships hulls don't flex. If they do they're too thin. It won't work if the hull doesn't flex. Duh! Maybe it would work on MacGregor hulls? Cheers, Ellen |

"Jeff" wrote You really should attribute things like this; otherwise its just plagiarism. I think plagiarism is when you try to take credit for something somebody else said. Everybody knows Joe's not a shark skin researcher. He'd never be able to come up with the shark skin thing on his own. I think he was right not to give the source. It's embarrassingly dumb and it'll never work. You have two choices. 1--Kill the growth with poison paint or 2--Get it off with a scraper, scrub brush and sandpaper but you have to do it about every month. Cheers, Ellen |

Cheers, Ellen I use to have a boss that once a month would invite some of his employees to his lake house to go sailing. Then he'd hand them brushes and scrapers and put them to work on his boat. Very few ever accepted twice. -- jlrogers±³© |

But now he's probably got kicked off Supernews and has another ISP. Hee heee! Gilligan was talking like he was gonna get gayganz tossed off. It looks like he succeeded. So now I'll just have a good laugh and block sender one more time. It's easy enough to do.... Now, if only he'd get a good case of the AIDS so we can be rid of him once and for all. Cheers, Ellen |
