Thanks Mike.
But that's not one of mine. I just grabbed the pic from the web whilst looking for info on stepped hulls.
But yes I do generally keep the tips just above the keel line. Just dropping them down a bit for windy weather & rough water is sometimes all you need to settle the bow down a bit.
Here's one of my favorite pics of my Arowana with the tips just barely cutting the water.
I did find some info that corroborates what GotRPM said. COG just ahead of the first step. But also with the stinger set parallel with a line from the front step to the transom. At the moment it's parallel with the last step. Something to play with now.
