I don't have a horse in this race a my boat already has speed & launch control but on the knob vs button question, I'm leary of knobs with as many Polk audio knobs we've had coming off! But those are in a much wetter spot.....time will tell.
RideSteady: Hands down the best cruise control system for a YAMAHA, if you ever try it I think you will likely agree.
I've taken my R-S just about anywhere by now... And I mean... Bimini 2017 crossing was... no joke and all salt, I've used the R-S for over 200hrs total. Peviously I've had the PP for maybe 100hr (total engine time, not PP use) but used very sporadically not constantly like I use R-S (for various obvious reasons, the old PP servos would burn and it was not easy to change setting under way).
The buttons/arrows require some dexterity to push and hold, the R-S knob is easy to grab or slide your finger over it, even gloved hand which I do a lot in the Fall/Winter. In my situation, I can lock/support my elbow on the coaming/side of the helm and easily operate the knob even in the most ridiculously rough conditions.
Maybe if the buttons are as big as the buttons on the Connext joystick pad it would be different? - those are super easy to push and hold. But if the new PP buttons/arrow shaped are the same as old, this is not even remotely close of a contest, IMO.
If they use the same screen, about half of those die about a year or two in. They turn black (easy replacement, BTW, for ~$300).
But really, I'm wondering as I write this: has ANYONE used the JBP PP in a Yamaha, yet?
EDIT: BTW - the patent battles in that space is actually interesting story. PP got caught stealing the patent from Econtrols/Zero-off, and
promptly settled to basically be allowed to continue providing servo-based speed control in non-fly-by-wire boats. But the original patent expired recently (2016?), anyway. Search for PerfectPass / ZERO OFF agreement if curious. Looks like no one can touch factory (OEM) fly-by-wire systems for speed control (Zero-off has that covered?).
