If the sea conditions allow it, my "cruise" speed is 45, just for the fun. Sometimes 30-40 knots with more waves and a hard ride. However, unless I manage to ride the tops of the waves I have to drop to a slow 20.
Your speed observations are similar for my 7.2 ballistic / 250 single.
She loves going fast but like you say when you can't skim from wave to wave you have to drop from 30/40 down to 20. This only happens in quite significant waves, however.
25knts seams an unpopular speed with this hull.
