Well ... I had a rib that did this from new, I varied the engine height and the improvement was negligible, the steering input on a 5.8 M boat is impossible to correct that fast from the helm, when the chine walking takes place .. .. in short the answer is too much power which ever way you look at it IMHO .. and the thought of getting thrown from a RIB at full bung is not a happy one when it slaps to one side and hooks as has been said ... been there got the T shirt

BTW Wilk .. I got it .. that wigglers a naughty boy

"overpowering" can certainly be a cause of it
good so we agree its a potential downside of overpowering.

I assume you mean iso 6185.62?
.62 ?? Given its size probably 6185-4 (section 7.2) https://law.resource.org/pub/bg/ibr/...185-4.2011.pdf

I'm not entirely sure why the distance from helm to motor would matter, hydraulic or manual should still be direct, with no delay. If there is, then you have air in the system, a slack cable, or a problem with the motor!

Yes, it has the potential, but then so does 101 other things. My original question as to why it would make it chine walk was asked because I read your reply as you stating "fact". (it would definitely occur) where as it's quite possible it would as someone else asked "just go faster"

As I said I'm rusty on all this now, haven't studied it much since i went to all the federation seminars pre 98. Having had another think on it though, I reckon if we assume by over powered we're referring to it from a CE point, then it probably wouldn't be, as I suspect it's a "commercial" boat, so is exempt from the rulings. IMHO of course

Actually, that's what we call a "trip and stuff"! there was no backing off, and there certainly wasn't a "hook" involved. Not really any chine walking either, as the driver had that under control. No driver error either, just a racing incident.

Here's a vid that shows how overpowering can be controlled, with a lot of knowledge, and a huge amount of ability...
