Congratulations Simon.
We were out on ours in flat water yesterday and never fail to be blown away by the handling of these things. If feeling bold (and secure within the boat) you can be going along at full chat (say 17/18 kts) and pull the tiller right over and the thing just grips and turns in a ridiculously tight circle with no skidding or washout - look back at the wake and perfect 'S' trails are left.
I guess it's technically not possible given the clever two piece V floor design but it would be fantastic if Bombard could somehow flatten the rear of the (draggy) deep V towards the transom (like a RIB) to improve top end speed and also hopefully lose the waterjet out back.
If not already seen I posted in these topics with minor mods and set ups:

At the weekend we were running slightly lighter and I was pleasantly surprised at the (relatively) large increases in speed - by ditching the drybag I normally have in the front and using the regular 25 litre hard tank (rather than bladder) right against the transom I even saw 19.4 kts max on my own. A bit flightly up front though with the lack of weight (still had the heavy Peli Case midships though) so for bigger seas I prefer the improved feeling of being 'planted' with some bow weight.
