As long as you're running your boat just for fun, having a high gloss running surface is OK, but it adds drag.
I scuff the running surface of my competition boats wit 600 grit (length wise!) until it is dull.
A waterfilm will cling to it and act as a lubricant.
Tests with identical hulls showed the scuffed hull is quicker, both in topspeed and acceleration.
Once the boat is up and running, you can GPS test it for yourself.
