In Response To: Skin Friction reduction (John Umlah)

Hello All:

I suppose I am kinda answering my own quetion now but I have been doing some reading on the skin friction of hulls of boats. I have found that if a surface is textured properly then the water cavitates due to the reduction in pressure in the zones of the small "pockets". The resulting air bubbles act as small ball bearings reducing the surface area in contact with the water. The theory is good but can it be done with conventional building techniques? Is it practical for a recreational paddler?
