I don’t think anyone is suggesting that you not count passengers toward displacement, rather we’re just saying it doesn’t matter how many passengers we have we’re still going to fill our bags as long as our boats will pull them.

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.

Love it. This amplitude bar measures hull draft—basically—yes? Excellent idea. I could learn the limit and know before working the piss out of the motor in vain.

Except that prop is the one thing you can’t control ... I’m the perfect example for that. Ordered the SL400with the 2277 prop because it worked well in my 2017 Malibu 23LSV ... except that the SL has a 1.5:1 tranny and not the 1.76 ... call me stupid because I was ...

So you would need to know pretty much every prop combination and test it to tell if the boat can do it or not ...

I learned the lesson quickly as nothing was happening when loaded up so got a different prop ... and it runs fine since. But with 5 people, 4 dogs and the additional 800 lbs of ballast the engine is running at 3800 to 4000 to push the weight ... and the wave is marginally better ... snot like your getting another 10 feet to play ... maybe 1 or 2 ...

As said before by others ... there’s only so much the boat can displace effectively regardless of engine ... except you consider a submarine a great surfboat
