I've been watching the olympic swimming and notice that nearly all of
the swimmers wear the new performance swimming suits. I did a bit of
research on the web and came up with the following quote from Speedo:

The LZR-Race suits promise to have 5 percent less drag than Speedo’s
previous best FASTSKIN PRO suits that have helped break world records
in the past year. Speedo also claims swimmers will have 5% better
oxygen intake efficiency thanks to stronger core compression section
along the abdomen area.

I wonder whether this phenomena applies to boats? Should we be
attaching shark skin to our boats?

I have seen the dinghy sailors polishing the underwater surfaces of
their dinghys with 2,000 grit sandpaper and wonder whether this might
actually be the wrong thing to do.

Is there any empirical information regarding the application of this
technology to boats?

The skin from a couple of Great Whites would just about cover my underwater
hull. Do you know anybody who could sell them to me?

Probably best if you get your own.

Forget it, Bruce. It would never work on a boat like yours that stays tied
to a dock for thirty years.

3M made a boundary layer film years ago. Presumably the results were not
stellar, or we would still be seeing it.

Give it a few years. U. Florida has been studying shark and porpoise skin
for some time trying to produce a low friction non-depleting non-toxic
anti-fouling coating for the Navy. Last I heard they were in full scale
testing.

I was under the impression that anti fouling paint, or copper sheets
for that matter, work only because they are toxic.

Seen a boat with the 3M Teflon based undercoat. Did not last long and
was a major bitch to clean off for something that would last and work.

Thats true, unless you can find a new material that will not allow
anything to stick. Ever see a barney on a shark?

There were some "Snake Skin" coatings that were rolled on in 6 layers.
Once anything stuck the friction would make the paint layer shed. Ok
but major hassel to apply right.
