Permanent Hydrophobic material

Apparently, its permanently anti-fouling as well. Maybe in the future, aluminum hulls with this technology with by the norm.

Re: Permanent Hydrophobic material

"Commercial use of the technique will require further work to scale up the process, the researchers acknowledge, since it presently takes an hour to create the patterns on a 1-inch square sample of metal."

Lets hope they can scale this up some or we will have to have very small boats.

Re: Permanent Hydrophobic material

I still like the old nickel alloys. Some are still sailing around, slime free.

Unfortunately "Hydrophobic" and "Self cleaning" do not imply any antifouling properties.

If a technique like this did work imagine how paranoid you would be with anything contacting the hull and damaging the finish .

The article specifically mentioned anti-fouling.

That true regarding the paranoia! You would be paranoid.

At the very least it could be used on things like rigging pins, split rings, electrical nick-nacks... or imagine never having to clean your stainless.

In any case, I'm an ever eternal optimist when it comes to someone figuring out how to scale new technologies up. If there is money to be made someone will figure it out. For example, they could use the same technique as us used in CD manufacturing, where the laser burns an image into a photo resist and then a chemical is used to etch the surface.

Re: Permanent Hydrophobic material

Hmmm, the same web site has an article on scientists claiming they have found proof of alien life.

Well it's on the internets it must be true.
