How do I do it? I can feel (and see) the bow rising as I accelerate, leaving the trim alone; then the boat levels as it gets "over the hump" and onto the plane. This when I start to trim out; a little at a time to let the boat settle; the boat should accelerate more without additional throttle as the drag is reduced. Eventually no more benefit is gained or the boat slows - trim in a touch and enjoy the ride!
(Turning: big wide turns - leave the trim alone, probably; tight, fast turns - trim in to prevent loss of hull grip and/or ventilation).
There are people on here who know far more than I do; and if you haven't already I can recommend the RYA powerboat courses.
Each boat will vary, and each journey will be different; and as loads change through the day so the settings will change. The dials and numbers on the console are only guides - as you get to know your boat you will feel what the right settings are for each occasion. This is part of the fun of driving a fast boat...
