The Daily Mail URL has a sketch that suggests there is "Neck Head
Support." It also shows the pilot/passenger/specimen/spam in a mostly
upright position - there is bend in the knees with "buttocks support."

My question is "how does one launch a finned rocket from a submarine?
I suppose they could fold-out after leaving the tube but still... Or
is the "submarine" just that red-painted rig and it is going to launch
a la Sea Dragon?

That would be heavy; so, instead, make a reasonably close-fitting "suit"

I wouldn't be surprised if he wears an inflatable "G-Suit" like is worn
by fighter pilots:

The test launch of the rocket is now scheduled for today (Thursday) at
the earliest, although they have a launch window that extends to
September 17th.

Isn't he only supposed to pull 3 g's though (at least on the way up)?
That sounds survivable without injury if he's fairly light in weight and
in good health.
I'd be more concerned about reentry G's...on Shepard's flight his
Mercury hit a max of 11.6 G's during reentry, so I hope the top part of
that rocket is designed to come down sideways rather than nose or tail
first, or otherwise the pilot is going to be in for a world of hurt.

It lifts off from a catamaran raft towed behind the sub:

The Danes don't have missile submarines.
So why not just launch it from a surface ship or a raft towed behind one?
So if the rocket blows up, the sub can just submerge.
In fact, I suspect the sub will be submerged when the rocket launches
for safety's sake
The sub involved is so small it is nearly a minisub from the photos of it.
Apparently, they built the sub also(!):

Well, Saturday has come and gone, and no news from Denmark concerning the
rocket test.

They were supposed to launch today at 1200 local time, but had to
postpone it until 1300 because of seasickness. They needed an hour for the
pills to take. Now it's almost an hour past 1300, and in Osten nichts
neues.

Scrubbed. LOX valve failed to open.

Yeah...that old problem.
That happened on a Viking rocket also, when frost caused the vent valve
to freeze shut, and they had to go out and shoot a hole in the Lox tank
with a rifle to prevent it from over-pressurizing and rupturing.

The plan to command the valve to shut in case of deviation from the
flight path seems a bit shaky. They better have a backup charge to blow
the LOX pipe.
