I still worry about accidental child knock down of the control levers though!

Well, in fairness the concern about children playing with levers is even more understandable with traditional mechanical levers, since both stations are always engaged and mirrored in their movements - so, they could be a sort of children magnet, I suppose.
Though nowadays most kids are likely to learn how to take control from an electronic station in a no time!
Hard to think of a solution to that. Maybe a keyed control unit...? Not that I've ever seen any, just saying.

But in contrast on my brother's Aquastar 74...

Yup, I can imagine that she's more akin to my old lady.
Still, I seldom used throttle levers also with her. The main difference with P boats is that I had at least one prop spinning almost at all times while maneuvering, which in my experience actually grants a more accurate control, compared to P boats where you must constantly engage/disengage to avoid going too fast.
That said, I agree that if and when you must combine gear engagement/disengagement with a bit of throttle, single levers are more intuitive.

The time delay with electronics isn't a problem in real life

Agreed, but it's nice not to have that anyway!
For some reason, whenever I used boats with electronic throttles, that split second sometimes has been enough to make me nervous at the thought "WNS, if the actuator jams right now...?"

Maybe that's what you meant

LOL, naah, you know It wasn't - your Maretron installation is very interesting indeed.
Thanks (a lot, I guess... ) also for the EN explanations!

PS: apropos of your previous pics, just curious: have you got rubber fuel lines also for engines?
I half recall to have read somewhere that they aren't allowed in coded boats.

Yep you need to be careful with mechanicals and small children.

Thanks a lot = perfect. Merci beaucoup!

Rubber fuel hoses are ok under UK coding and I've never heard of them being non compliant. Obviously you need some rubber in the line because engines move. I have much higher liquid pressures in other rubber hoses in e/room: watermaker and hydraulics for example. Every car on the planet has rubber fuel hoses and most fuel pumps on the planet are diaphragm pumps with a rubber diaphragm in contact with the fuel. I think I'll file it in the "Don't worry" file, alongside Delta* and dreadnought anchors
