@Horton Thanks for your help. I suspected maybe the two different lakes (shallow and deep) might make a difference (I've heard it can make a difference with surf and wakeboard wakes.) I'm going to try a few variables of the tower off... stripping the back seats and bow cover off, etc and also run the Prostar on the shallow lake with the same config that I've been running on the deeper lake. I haven't been as thrilled with the Prostar wake at 15 off 30-34 mph... but was thinking that might be more due to the lake depth, course set up...or the extra stuff I have weighing the boat down. I have skied a Prostar with no tower and seats on the shallow lake and it seemed pretty comparable to the Nautique. Could have been my mentality and technique too.
@eleeski I'm not sure what exactly a "troll thread" is. If you're implying that I'm trying to be negative about the Mastercraft or something compared to the Nautique or bash the Mastercraft then you're dead wrong. It's a fantastic boat... it is rock solid in every way and I wouldn't have bought it unless I did some vetting before hand. My wife loves the wake at 28 mph and we love the layout.
My intent was to get a boat that was a little more multipurpose and family oriented without compromising the adult speed ski wakes. My focus is not "drilling" the kids on slalom... it's to let them develop and succeed in whatever they want. They even love tubing behind the boat and I love driving it for them. I'm not trying to start any rumors about this hull or anything of the sort. I have no such agenda. I'm throwing these questions out to an experienced community of skiers who may have juggled some of the same variables in order to better understand how I can maximize the performance from this fantastic machine.
