Makes total sense to me. Breaking the surface tension will reduce the percent of the bottom that is wet. There in no denying the dryer the boat the faster it is.
What I get from the theory behind speed coat is that is basically roughs the surface up. It's kind of like a flat paint. There are millions of little peaks and valleys as opposed to a shiny surface where it is pretty much smooth. Each of those valleys ( or peaks depending on how you look at it.) is a place for air to hold. To exaggerate the theory if the valleys = 50% of the surface you have just reduced the water contact by 50%. By this theory, what Scott says makes total sense.
Kinda like indexing plugs, it's a tiny advantage BUT to the guy out there looking for every last fraction of a HP it can make the difference.
Just My .02 I'm kinda new at this though so I could be completely of base.
Well said, and when your talking tenths or hundredths at the track, every little bit of tunebility counts. For us weekend warriors, we are probably not going to see any "seat of the pants" difference. Fixing a leaky ineffcient pump thats been neglected for years will probably help out the average lake guy more than anything.
