Not me Ian, probably Rachel at the helm as I'm frightened to go fast
Whte Lady is a deep V or a modified V which gives less lift for each kt of forward motion than the type of hulls Perry and I have, they are thick at one end, much, much thicker in the middle and thin again at the other end, no wait, that's Dinasaurs.
They are (unlike Dinasours) quite pronounced V at the bows then quickly flaring to much flatter sections aft so a bit like a tea tray that gives more lift for a given speed, it also requires a bit more power to reach that given speed. Also as Perry has said they are able to behave better at river speeds, especially if they have a bit of a keel. However, as in all things there is compromise, if I were to be able to shoehorn enough power to reach White Lady's speeds then in aything other than a flat calm she would slam, crash and probably break the hull (oh no not again) A deep V entry, leading to say a medium V at the stern will give a much softer ride in a bit of a chop at higher speed. Yer pays yer money, yer takes yer choice.
Trim tabs only make a little bow down difference and I really can't see why they were fitted to the Serie 9, on a deep V however they are essential, not really to assist over the hump, drive trim is better at that, but rather to help reduce list in a side wind or beam sea.
I'm really sory about your wine and I will have my man "bring round" a case to replace it when I am able
Edit to answer your last question Ian, yes, loads, the more stuff and peeps at the back, the worse it becomes.
