I found wet sanded with 600 grit was the fastest but only lasted one or two races, because it would pick up crud.
Then I went to polished, and it would last one or two days until it picked up dirt, oil, grime, etc. from the sea.
I was never into cleaning the hulls every day. I ended up going with teflon polish, though it wasn't the fastest,
it had the best longevity over a week long regatta for an overall average, by keeping the grime off.
This was mostly gaged by how often I got clear air off the starting line, and butt dyno.
There may be something even better than Teflon by now to keep the film off.
