The aircraft carrier Cavour after launching. She currently has no bow.

Keep it in mind though, most of these examples are newer ships, what about 1920's/30's building practices?

AFAIK Germany at least built several ships or boats on one slip at the same time. but that is only a hazy memory. apart from there already have been period examples given in this thread.

So can we have a show of hands on this question,

I propose that multiple vessels can be built on a single slip (or in a single dry-dock) providing the following contidions are observed....
1 - Hulls must be in single file, line astern. ( Drydocks may, space permitting, have 2 files )
2 - A working space of 10 metres/ 33 feet between 2 hulls
3 - The turnaround period for the slip be equal to the maximum that size of slip needs.
4 - No ship may be launched while another ship is building "in front" of it
5 - ALL vessels on a slip or in a drydock must be launched on the same day.

Your thoughts please!

If we add...

4. No ship may be launched while another ship is building "in front" of it

...then I'd support it.

I'd suggest that ships building in a drydock could be built side-by-side - provided that they are launched at the same time.

Otherwise 1-2-3-4 all OK with me.

Sounds fine. I'd mention that some slips are parallel to the water so the ship slides of broadside first (submarines are famous for this) instead of end on.

Seems fine to me.
