Thanks all for the encouraging comments.
The only thing, i don't see the enter on the bridge? From where we will be able to enter/exit the bridge ( i hope we'l be able to enter/exit bridge ).
Gosh... silly me, I've forgotten the doors for entering into or exiting from the bridge! Oh, that's not a problem after all, here's the solution to solve that: put the crew members there directly in the shipyard during the construction of the ship and before the ceiling of the bridge is done, then let them be enclosed here for the rest of their life or until the ship is scrapped some 30 or 40 years later...
Seriously, joke aside, you can see 2 doors on the aft bulkhead, on each side of the charts' chest of drawers. They both lead to a transersal corridor that leads to the outside through 2 doors, one starboard (below 1st screenshot) and one port side (below 2nd screeshot). This transversal corridor is mainly for crew, captain and owner use.
On the 3rd screenshot, you can see a succint layout around the corridor: 1 is the bridge, 2 are the captain' quarters, 3 is the owner private area (however, his/her large stateroom is located 2 decks below, behind the 4 large vertical portholes you can see on some previous external shots of the yacht), 4 is the downstairs access for crew only and 5 are the downstairs and upstairs accesses for everybody, but the owner or captain can choose to close that access to the guests if needed.
So, like some other yachts, there's not necessarily a direct access from the bridge to the outside (and as far as I know, MCA regulations, for instance, don't impose that) but, for mooring manoeuvres or sailings into narrow chanels or locks, these 2 doors you can see on the above bridge screenshots can be left open as well as the ones leading to the exterior (the 2 first shots below) for a quick and almost direct access to the bridge wings. The distance to go from the bridge to these wings is very short anyway.
The advantage of this layout is to allow a better security in the owner's and captain's quarters and in the bridge from potential agression or attack from the outside (this kind of ship can sometimes be very exposed and rich yachts owners tend to be sometimes a bit paranoid -justifiably or not).
That layout allowed me to resolve the independant crew/captain/owner access from the guests if needed, as well as the use of the flydeck above for everyone, without entering the internal private spaces there, as long as the owner or captain allow it.
When I build a ship model, it is not just an excercice of style or a sort of "3D showcase" only but before all the design and validation of a nautical/structural/architectural/functional/commercial concept where many thoughts are put and searches done, in order to make it as plausible and credible as possible. When I design a ship, I'm a big fan of realism, in all domains and I don't really like improbable creations. In a simulation, the immersive experience once aboard is far greater because of realistic graphics and behaviour, but because of a credible feeling of the ship herself as well.
Starboard access.
Port access.
Layout of the Bridge Deck near the bridge: 1= bridge, 2= captain' quarters, 3= owner private area, 4= downstairs access for crew only and 5= downstairs and upstairs accesses for everybody.
Again, thanks all for your comments, a new update will follow soon.
