Did about 5 years on an azipod ship.
Emergency stop procedure was to turn both drives pointing in and give it some welly.
Very effective at:
a) stopping the ship,
b) setting off all the UMS alarms as the on-demand engines kicked in.

Win/win really - avoided collisions and annoyed the engineers.

That's got me looking at azimuth thrusters.

Azimuth thruster - Wikipedia

Has this developed into the pods on floating blocks of flats they call cruise ships? Again watching these arrive and depart at various harbours fascinates me as to the degree of control they have in heavy airs.

Yes. I am not generally an enthusiastic supporter of Carnival Cruise Line, or of Rolls-Royce, but I think the Queen Mary II is a true masterpiece of modern shipbuilding.

ProMariner expresses, pretty accurately, the feelings of all professional users of the sea towards naval personnel, anywhere in the world.

On the other hand, professional seafarers get to have their own cabin, which is nice, they get to see the sea, and before Covid-19 they sometimes got a run ashore in places more interesting than Portsmouth and Plymouth.
Since ISP(is)S, they've been pretty much confined to quarters when in port, no?
Since Covid, they've been even more stuck on board... some were doing 18-month tours as they couldn't get repatriated during peak lockdowns.

I don’t entirely agree, which is unusual as we usually march in lockstep on this stuff.

The ISPS issue only really applied to the US of A ( I’ve got a friend who makes a point of marching down the gangway to use the landline phone, just to annoy the Homeland Security goons) and that was US domestic legislation - anywhere else you could get ashore although in a few places (Venezuela…, Mogadishu…) you might want to think about it.

Covid has made things far worse. The low point was reached when Australia, who made it completely impossible to change crews, detained and fined a BW ship because some of the crew had gone over their contract dates. I kid you not. And BW are good owners.

However my own outfit have been lucky and have pretty much always succeeded in getting people home in time, although this did sometimes involve crew transfers by boat OPL Singapore! My former employers have also generally managed it.

More than happy to take your word for it; you're a lot closer to the sharp end than I am.
But I do remember quite a bit of talk about seafarers not being able to get ashore when ISPS was introduced. Apostleship of the Sea and other charities were quite concerned.
From what I understand, the fast turnaround times these days don't allow a lot of shore time either.
I'm glad your lot managed to get repatriated, but a number of the carrier ceos I talk to were getting desperate about having crew they couldn't get home at the end of their contracts during the peak of the pandemic.
I think things have improved now but for a while seafarers were persona non grata, even though most had been isolated at sea for several weeks before they showed up in any port, so if they were carrying Covid it would have already showed up.

A friend of mine has recently qualified as a Third Officer and her first appointment has been to a cruise liner. She sent me some information about the use of thruster pods; it was very interesting to see that they have to be coordinated quite carefully to avoid placing unnecessary stress on the system.

My friend was still a cadet on a bulk carrier during Covid. She couldn't get back and her cadetship was extended several times. She ended up having her sea-time in when she did get back to Hong Kong, so in one way it was good!

Yeah, every bit of machinery on any vessel has its operational limits.
