Bottom Paint "orange peel"

[tj55]

I have just put a first coat of bottom paint on my PocketShip. I'm using Interlux TriLux 33 with the recommended 3/8" nap roller. I have never used antifouling bottom paint before and am wondering if the "orange peel" effect is normal or am I applying the paint incorrectly? I am used to "rolling and tipping" with Interlux Brightsides paint to get a smooth paint surface but bottom paint (or at least the one I am using) doesn't seem conducive to that technique. Any suggestions or is an "orange peel" effect the price you pay for bottom paint?
