Re: Malibu RCB trunk delete
So with the theme of dropping weight, moving around the swim platform is ridiculously heavy. I mean holy crap after 20+ years of ski boat building in the new age you think they would do a lightweight platform. The platform sits behind the hull and as far as a leverage aspect is more important than weight loss inside the boat. With that, I like working with aluminum, so an all aluminum platform only makes sense to me. The aluminum I used is 1 1/8” x 6”. It is the same stuff that is used for outside bleachers and joins/hooks together to make it very strong and light weight.
Got the size I wanted and cut out the pieces to shape.
Put a 1” tubing frame around the whole outside. The bent tube that is closest to the boat was kerf cut every about 6” to get a nice radius to match the fiberglass hull.
Then had to weld a piece of flat stock on where the brackets were going to attach.
Put the bracket on the boat, mark, drill, and bolt brackets on.
The aluminum plank had the no slip ribs/textured top and I was going to wrap the platform with EVA foam so I did knock those down with a sanding disk/grinder somewhat. Also put plastic cap inserts into the ends of the 1” tubing so there was no exposed sharp metal edges.
Wrapped the whole thing with EVA foam I got from eBay for fairly cheap. Had to notch the corners get get them to wrap around the corners nicely. It’s not perfect but I am happy with it.
The foam had sticky back on it but I was not going to rely only on that to keep it attached to the platform. 3/4” strips of aluminum pop riveted around the whole perimeter of the platform hold it on nicely.
Finished product. I love it. Original platform was 50#. New platform is 25#. Platform never really gets soaked as it sits about 6” above the waterline.
Re: ProStar MTS Ballast System and Storage
are correct in their comments. The tank's level is controlled via the touch screen. Its basic purpose is to balance out the boat so the wake is not adversely affected by not having an observer; just a driver.
I believe the new system is still on a timer like the 2014-20 ProStar. The factory told my dealer that the leaking issue at speed has been fixed for 2021 by using new Tsunami style pump (see my first post in this thread). I don't know whether it is one or two pumps. I assume this fixes the leak at a stand still also. The ballast tank level is also able to be saved and assigned to user profiles so when they are activated, the ballast will fill or drain to that saved level.
Hope this helps.
Re: Fin Settings - Personal Standard?
Yep, did the math. Fun exercise if you're really really borred. Had to digitize a fin into CAD to get the raw data. It was a Radar fin if I remember correctly. The resulting equation is quite accurate. Never got around to doing it for a CG fin.
For what it's worth, i don't use the math, i did it more as a sensitivity study to see how depth and length effect surface area. As you can see in the equation, you pick up quite a bit more surface area for every thou of depth than you do for every thou length. It is definitely not a 1 for 1 relationship.
Fortunately for me I figured out several years ago that all I have to do is call up
and ask him what he's running, then i pull about .020 of depth out and take off a degree of wing and that usually works pretty darn well. Basically i let him do all the voodoo then just free up the ski a bit... I don't pull as hard. I'll tweak a bit from there, but he puts me in the ballpark. It helps if you're riding a ski that is very forgiving to setup.

Re: It is time for your yearly Who Are You Guys thread:
Hi, I'm Larry. 65 years old. Learned to ski at around 9. Fortunate enough to have a family boat and a summer place on the water. A few years later, my dad traded the old woodie for a 66 Correct Craft Mustang. Became enthusiastic about the sport around 16 - 17. For my age and experience, I should be a much better skier and barefooter, but I was never exposed to or had access to show skiing, a slalom course or competition. I just did it for fun. At 17, a friend and I taught ourselves to barefoot, certainly a novelty on our small lake in 1972. Fast forward to post college years, and a move to Houston. My own boat, regular skiing and footing, but still no course work. Stepped up barefooting by graduating from dropping a ski to deep water starts, tumble ups, tumble turns, one foots, toe hold. Never got backwards despite a few futile tries. Next chapter, family and kids. Little to no more skiing with "ski buds." All family time on the water. Kids became good skiers/wakeboarders. That lasted about 15 years. Now its about 2005-2010, kids are pretty much grown and on their own. Super rare access to a course, but met up with some footer friends that reignited my interest in going backwards. In my late 50's early 60s taught myself short line then long line back starts. In this recent chapter, also getting some exposure to courses, in fact, have custody of one now. Again, despite having over 55 years of experience, I am just now graduating from being a 15 off to a 22 off skier. But the challenge is real and fun and making 22 for me means as much as making 39 means to someone else. Here is a little video recap, its a little crude, but it is now 15 years old. I did it at the infancy of do-it-yourself videos.
Re: Hilltop Lake ProAm by Syndicate Waterskis
No Elite Points? What a shame that the arbitrary, mostly useless, ill maintained Elite List won't be a part of this event
Thanks to everyone who's helping put this event together. Very exciting to be able to do some real skiing in a year like this. I'm very much looking forward to it.
