It's a shark....haven't you ever seen a hammerhead? I thought you were
in Florida? 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.

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.

Now that's interesting. I wonder if a shark-skin suit will people off my
back?

You really should attribute things like this; otherwise its just
plagiarism.

Nahh, you will find the link and post it for me..

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

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?

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.

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.

When I was a teen, I had a boss with a big motor yacht. At
haulout he'd take three of the lowest paid shop guys down on
a Saturday to wax/polish it. We got paid overtime and were
happy to do it.

I pay you a low wage plus 1/2 to come over and wax/polish something of
mine!

I put this jerk Capt. JG in the blocked senders list. 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.
