If you are willing to spend $100k+ on an oversized jet ski, I would at least demo it, a Cobalt R3, a high level Tritoon, and an Axis A24/T23 or Mastercraft XT22 and see want kind of boat suits your needs and that you prefer to drive. If it’s the wakeboat style, every brand pretty well has a $100k option at this point. If it’a the I/O style, there are plenty of options out there sub $100k.
Wakeboard boat - best option for pulling anything, most suck to just ride around on if you want to just cruise because of the hull design
I/O - decent option to pull especially beginner wakeboarders, best option to run up and down a large lake on.
Pontoon - ultimate party barge and cruiser, will pull anything but definitely for beginners or just tubing.
Personally, with no boat experience I would take Troph’s advice and pick up a decent used boat fairly cheap that isn’t going to make you sick the first time you hit the dock/sandbar with it. I have never bought a new boat in 20ish years of boat ownership. Too much crap happens to them and I want to have fun and my kids have fun and not worry every time something touches it.
I am a wakeboat guy. I love them, I’ve had 7 I think, I’m looking for a new one now, etc. Saying that, my pontoon and even the jet skis get used more than my wakeboat. If you’re building a lake house, you really need to think about multiple reasonable options rather than 1 high dollar one. I have a reasonably cheap pontoon that gets used to ride people around, a floating dock on the lake for people to tie up too and swim off of, all eating takes place on it, etc. I have jet skis for the kids and adults to screw around on individually. Then I have the wakeboard boat (not currently because I sold my last one) that pulls everything. The last group was probably $65k combined in all of that and every use is covered. Most every house on our lake has a similar setup although most have spent way over that for their toys.
