[PSUBS-MAILIST] Shark Skin Effect

[Garry Muir <garry.muir4@virgin.net>]

Hi Folks

There was some discussion a while back about sharks skin and the way the 
denticles produce a laminate flow over it reducing drag. I was looking 
through some scratch notes I made a few years back on trawl doors and I 
am quite sure a company tried rolling a pattern on steel plate that 
would replicate the effect and for some reason I think it may have been 
NETS of Seattle.
I will delve into my files or should I say large confused heap on the 
floor and get some more info, it may not be a practical finish for a sub 
hull but it may have some advantages on control surfaces and appendages.

Regards, Garry
