Jockey ergos

Does anyone know how far away their jockey seats are from console please? Trying to figure out the ergonomics of a jockey

When I put mine in I had to consider the console hinged back so the steering wheel missed the seat, also you need room for your legs to pass between seat and console other than that set it for comfort backrest and arm length IMO

Whilst it is aimed at suspension seats, it does have some good stuff on arrangement.

You then may need to compromise to allow locker doors to open, for example.

Stand up at your helm. One hand on the wheel, one on the throttle. Lean back a very tiny touch and yer bum should connect with the wingback. Sit down and you should still have good ergonomics. You may have to move the throttle or fit an adjustable wheel. Either way - make it fit you personally.

Appreciate the responses.

To be more specific. How far away is the front face of jockey seat to console or steering wheel I understand it’s unique but want to acquire opinions

I put mine at just over the length of my feet so I could get my foot through the gap and it also allows me to fully open the locker in the rear of the console.funny enough it works out just over a foot 35cm

If you stand up at the console, then you can get away with having the jockey seat about 100mm aft of the console. This is enough to get you foot out sideways but beerbelly's 350mm is also a sensible figure to get your foot out lengthways.

If you sit down and your jockey seat has a back, then sit in a chair and measure from the back of the chair to the ends of your knees and add 50mm to make sure your knees don't clash with the console.

Generally (and IMHO) consoles don't project the steering wheel far enough aft so you end up either standing or sat but reaching forwards or without enough knee room. Knee cut outs in the console work but impact on locker space or you could plant a box on the aft face of the console that houses the wheel and throttle.

I wandered around a couple of boat shows armed with a tape measure when I was trying to answer the same question but I came to the conclusion that there wasn't a 'standard'.

not gat a measurement but some idea of both seat set ups on my old rib if i was to guess 250mm back but thats for me hope that helps

Thank you. Great replies. It’s difficult with a blank jockey canvas

I did some digging today. My jockey is set back 470mm+ from the console footings, but my helm and throttle mounting are on a moulding that projects backwards. It works well.

I have an undercut console that puts your knees under the helm. I can sit back in the seat & comfortably steer & throttle. The trade off as mentioned is reduced space in the console. Another thing to consider is the position of the helm in relation to the seat, the helm & throttle should be either side of the seat centre line. The helm shouldn’t be central to the jockey. This isn’t always easy to achieve given the space constraints of a RIB, but do what you can.

I also set the passenger jockey slightly further forward of the drivers. my mrs has shorter arms so she can reach the grab bar on the console if needed and so our knees don't keep clashing. I only fitted single jockeys and the valiant console sort of curves back towards the driver so when seated I can reach the controls with my back against the back rests

Modified it for you.

Is your console in place and you are looking for the optimum jockey seat location or do you have an entirely blank canvas?

New console and seats. Latest design Console is undercut so steering face protrudes by 280mm from console footings.

It feels like steering console face should be about 500mm from seatbacks but I am not a giant so seek other perspectives.

I have a 280mm protrusion in theory like yours. Is 470 from console footing to jockey front footing? Or seat back rest?

I won't be on the RIB until Wednesday and if I remember, I'll take better measurements and a side on photo. The 470mm is from console footing to front of jockey footing - I measured the mat I had removed and had at home. It seems huge but there is is - at least 470mm without a doubt - maybe a touch more, depending on my mat cutting skills

If you sit on a stool with your back against a wall and hold your hands on a pretend steering wheel, that puts the wheel around 600mm forward of the seat back. If the centre of the hub of the wheel is 280mm aft of the vertical part of the console which is what both you and Willk suggest, this puts the vertical flat part of the console 880mm forward of the seat back. If the jockey seat is 400mm long, this would put the forward end of the jockey seat 480mm from the vertical flat part of the console which aligns with Willk's measurement.

TBH there is no substitute for mocking it up yourself because as you have discovered in this thread, there is no standard.
