I did a lot of waterskiing behind a 14 foot Dura Craft with a 25 Merc when I was a kid.
I've also skied behind my 16 foot Dura Craft jet. In fact, I just got through doing some modifications to a nice ski pole, made entirely out of stainless steel.
It's about 6 foot tall, fits into the pintle mount on the stern of my boat, with tube bracing that bolts to the gunwales.
Initially, I used some small diameter SS cable as guy wires to brace it, then quickly found out that didn't work when I snapped one of the wires while skiing behind the boat last summer. :roll:
The guy wires were really not a good idea to begin with, as they were small diameter, and it would be too easy to 'clothesline' oneself, possibly cutting off some body parts. :shock:
So, I did away with the guy wires, and instead used some thin wall SS tubing. The tube bracing is welded to the main tube, but I cut those brace tubes, near the main upright, and put internal sleeves made out of solid aluminum stock, turned on the lathe to fit snugly inside the SS tubing, then drilled for a SS bolt on each side of the joint, on both bracing tubes. This way, I can break it down into 3 pieces when I'm not using it.
Haven't got to try it out yet, as I'm currently replacing the steering cable in the jetboat as I write this. But I'm anxious to see how it works out! When I do, I'll get some video and post it to my youtube channel.
