I cant comment on anything Supra at this time, but i can tell you the moomba sensors are NOT on the bag or tank. They are standalone sensors that measure the water level regardless what bag you use. So as long as you get a bag that has the correct fittings, you can add a bag and it will turn off when full. I will try and elaborate more later but this is an industry first and should fix a problem the entire industry has been facing of inaccurate ballast timers, gauges, etc. AND we are working with wakemakers so they can make custom bags with correct fittings that will hopefully be available later this year.
Also, on the debate about ballast and capacity, dont forget we have draft sensor to also measure that accurately. I dont understand the idea that passengers should not be considered toward displacement (???), but at anytime you should be able to look at dash and see what your displacement is and that will directly relate to how big the wake or wave will be. We also changed the Moomba amplitude bar so it is now in 3 sections. If you want a decent size wave, you need to be in the upper displacement zone. On the Makai, you need about 5,000lb displacement to get there. So full ballast and 5 adults, or 2 adults and larger bags, or 2 adults and some lead will all give you the same result. Anything more that 5,000lb starts to get really awesome.
Hope that helps.

Looks like the Supra info may hit as early as this week according to a post I saw from Drew last week. Should be a fun week.

Really no place to write this post, but I just spent some time on an SL 550 in 11 feet of water with about 1200 pounds of passenger weight and 1000 pounds of lead.
Ummmmmmmm....YEAH. Holy balls. Incredible!
I truly wonder if a 450 could move that load. Simply because there are more 450s available out there than 550s at a nice price.

I think the point is simple, it’s a hulls design that determines max ballast for a given boat.
It’s up to the manufacturer to determine how much of that is adjustable ballast, occupancy load and added content and features.
If the hull doesn’t change you can’t keep adding adjustable ballast without reducing occupancy load rating.

I believe you were at 11300# and if I read what goose said about a fully loaded out makai at 11700# with a 400 and a wake prop pulling it fine.
I think a 400 would handle your 11300#, the difference in the 400 and 450 is 27ft lbs of torque.

That makes sense and we know that and expect it. Maybe thats another value to the amplitude bar. I've always thought of it as a way to set expectations on wave or wake size. But it can also set expectations on how much load you will have on your specific engine and prop. As you said, all boats eventually have a max displacement that the engine can push. With amplitude bar it makes that visible before you attempt to accelerate.
