Dome


Actually the forward dome was round.Some photos and early P.R illustrations have an elliptical look based on the angles they were taken.If you look at other photos,blueprints and models of the ship you can clearly see both domes were round.Besides ,what would be the logic in having one dome round and the other more oval in shape? When it came to all the basic features, these two ships were almost interchangeable,including the domes over the staircases.As for the dome being a later feature,that is improbable as the early illustrations( about 1910) done while both ships were under construction show a dome over the staircase.

No the forward staircase dome was oval, look at the plans Iv attached. The oval shape is the same as the funnel stacks. A circle dome would not reach both the wall with honour and glory and the curvature of the well down to A deck, so it had to be slightly oval. The aft staircase dome was circular, this is because the staircase is smaller in size and could fit a smaller circular dome.

I recall reading that the aft dome was oval and the forward dome was circular. Anyone know which dome is currently on the seabed? I reflected the second image to see what it might look like intact.

According to the Bruce Beveridge blueprints (Hosted on this site), the forward staircase dome was oval, the aft was circular.

The dome may have been a feature added afterwards, but the staircase and funnels were always meant to be exactly where they are. This is integral to the ship's design all the way down to the keel and the boiler placement. Basically, the boilers determine the position of the funnels, and the staircase just slips in between funnel #1 and #2.

The forward grand staircase is just grander than the aft staircase. Among other things, it has a larger vestibule, and the dome covers part of the vestibule. If you think of each staircase as a stack of round balconies surrounding a courtyard, with a staircase attached. The forward grand staircase has a rectangular court (with an oval dome), and the aft has a square court (with a round dome). So it's just an aesthetic choice. It would be totally impossible to put a smokestack there.

The debatable 4th funnel would have been the last one, which is over turbine engine room. No smoke is generated there, so there's no need for a smoke stack.

It's also used for ventilation for the turbine room, and I suspect a safety release in case there was a steam line rupture in the turbine room. But that's only what the shaft was for. The funnel which sat on top of the shaft would have hampered the ventilation more than anything else.
 
Actually there are a few more things to clarify for the round dome idea. First- Honor and Glory which has done a METICULOUS,bang up job recreating these interiors shows a round dome.I know the forward stairs were bigger with the extra balustrade and all, but maybe they made the dome bigger just to fit over it all.2nd-early illustrations including Britannic's staircase looking towards the pipe organ wall show a more rounded shaped dome. Finally, the glass covered casing above the boat deck covering the dome to protect it, is square.If the dome were truly elliptical wouldn't this structure be more rectangular as it wouldn't make sense to have a square covering over an elliptical dome?Every model, drawing and painting including those by renowned expert Ken Marshall all show a square structure. Don't jump on my case- I'm just throwing a few more things out there for reasonable discussion.

Shouldn't you check your facts before you make such statements? See attached images of the dome from Honour and Glory, models, and also James Cameron's staircase. They all show a oval dome or rectangle casing.

Well then I guess I learned something new today. If I'm not mistaken, the skylight was rectangular and the dome was ovular, so is this model inaccurate?

It shows a rectangular skylight with a circular dome.
