    You may have overlooked that they are using a bus system! So, rewiring is never a issue.

    Good point. We'll certainly leave enough space, including for future wiring and antenna cables .

    Always remember the top of the line bus system today is obsolete in 5-10 years
    Install raceways, lots of power and flexibility to change from day one.

    I doubt that CAN bus, Ethernet and NMEA 2000 will be out of use within the next 25 years. CAN was developed in 1983!
    But naturally additional space, power and raceways are never wrong. Especially if one is a kind of tinkerer.

    For sure I know!
    CAN bus, Ethernet, and NMEA 2000 are still the standards in the marine bus- industry, that is what we see in ten years.
    That is a pretty safe bet, because it is a time consuming and expensive task to install a new industrial standard worldwide. I.e. NMEA 2000 did not completely replace NMEA 183 until today! After almost ten years!

    What is wrong with last one, I kind of like it, looks a little cramp.

    Well, the flat surface in front of the instruments is useless, the cup holder in front of the E panel is not the best place. The monitors are out of direct sightline (good) but here they are a bit too much out of sight, should face inwards a bit.
    Passenger seating is too close to helm position (this is a 45m Format not a 60´ blue water sailer where you want your wife close to you), and do´nt face forward.
    Yes a bit cramp, I would prefer it a bit opener, you usually walk around on longer watches if possible.
    But the helm seat is a good one (Recaro i guess).
    All four are more or less good, I should´nt have used the term acceptable. Hakvoort is a premium Yard, they do´nt do crap.

    Good eyesight Richard. I missed cup holders. Maybe good to hold spare breakers... It is a little cramp in spite of being pretty big. Would you say chair is well position with steering wheel at least for foot steering. I never steered a ship sitting down.

    I am thinking of putting monitors on top of windows. I have height in my bridge. These monitor would be used for video of surroundings, news, and miscellaneous stuff. What do you think of this idea?

    I am also thinking of placing lounge area under windows and putting steering console toward one side. I have outside upstairs bridge that would be getting most of the use, so inside bridge is for bad weather. What do you think of this idea. I am trying to do some drawings.

    Monitors above the windows- I suppose it could work. Looking up is not comfortable for very long, so anything up there would have to be for things you aren't constantly checking- CCTV camera feeds from the side decks, that sort of thing. It would look way cool, for sure.

    LCD monitors should really be within 20, maybe 30 degrees of normal to the line of sight. A large, flat array (like the last picture in post #9) looks cool, but the outermost screens are at too big an angle to the helm to be useful. If one person will be conning the boat, that one person should be able to view all necessary information just by turning their head, without leaving the helm. Monitor banks would thus take the form of semicircular arcs, centred on the helm chair.

    Also on this note, control panels for frequently accessed functions should be within arm's reach from the helm. Anything more than 80 cm from the centre of the helmsman's torso is too far away to use without moving around. As I've mentioned before, I'm a small-boat guy and don't have most of these gadgets. If I were setting up a big-boat bridge, I'd want (at a minimum) the engine controls, autopilot control, radar keyboard and the keypad of the VHF within arm's reach.

    As anyone with a laptop computer will testify, a comfortable position for controls and keyboards is somewhat too close for a display screen, especially if you'll be just glancing at the display before looking back outside. A two-tier setup, with controls at about 60-80 cm from the operator and displays in a large arc somewhat farther back, is often a comfortable way of setting things up.

    Pulling key controls close enough to the helm to be easily reachable will almost certainly result in a control station that more closely resembles a jet aircraft than a ship. If you want the big open bridge look, some sacrifices in ergonomics for the one-person case must be made.

    If you will always have multiple crew on the bridge, of course, things can be different. In this case it may make a lot of sense to spread things out among two or three stations.

    Well, it is nesseccary to have some sort of vast overview if one has to command a ship, I guess.
    The chair is in the right position (always just a bad compromise). Today the AP does the job and steering is usually done by hand in tight quarters only (even then mostly with a tiller). And I do it like you, if handsteering is choosen I do it standing at the wheel.
    The monitors overhead is a nono, they produce senseless pictures (too small), disturb the eye (fatigue) and are inconvenient to read (high angle). Security monitors as Matt mentioned could be placed overhead but not within 1,2 meter from centerline of the wheel (that means you cannot read them anyway). The overhead panel is good for searchlight control, windvane, and the displays of your backup systems (if low dimming is possible) and all the fancy little chistmas gimmick gifts, bridge clock, baro, inclinometer etc. (all in brass naturally). Never allow a TV connected monitor at the helm, never! (except it is only you and your female admiral doing the job, of course).
    If there is no Palm tree at the foredeck (where some silly people hang fabrics at), I prefer a centered steering position and would not give it up for any sort of convenience. But of course that is just a very personal preference, and I am talking about passagemaking (as in all of my statements) only, not weekend sailing.
    That is the industries luck, that 99% of theyr customers do´nt know that 99% of the boats a far below a sensible standard of ergonomics.
    The pictures 1 and 2 show pretty much what I prefer (pic.1 is about ten years old now, the PC monitor is a flatscreen now), a single purpose bridge. A no nonsense, no food no beverage at the helm, this is a workstation, bridge. And this is the boat from the outside:............the right one..

    "Security monitors as Matt mentioned could be placed overhead but not within 1,2 meter from centerline of the wheel (that means you cannot read them anyway)." Why?

    What do you all think of these three...

    To be out of the direct sight line at night, mydauphin. And the pictures you posted show all pretty much reflections especially the last two (I guess a fast passenger CAT bridge?). Who will handle the VHF radio in the first pic. ? What does the second show? A wheelstation in the basement?
