Why are Sealion threads so hated on this site?

Yeah your more than likely right, on a similar note I doubt the S-H boilers were as capable or even worse as reliable when pushed as they initially where (given it's decades long non combat role, and tight operating resources of the RM/KM). So that power disparity is likely even worse, and the S-H even more comparatively underpowered. We can go into stuff like armour plate in 1906 probably isn't up to the same standards as WW2 stuff, what was the state of those hydraulic pumps for the turrets etc, etc. Basically lots of issues with putting ageing and for what of a better term earlier generation stuff into fight.

Well she's not even an earlier generation, that would mean she was a Dreadnought, she's two generations removed from modern vessels. And very good points about her engines, they'd be worn out, its the nature of a triple expansion engine and how they work, that many moving parts and this causes wear and loosense the machinery. Its what made triple expansion engines so darn maintenance intensive, because after lots of running or use for a sustained period you get a lot of play in the engine and this can be bad as you'll then be getting vibrations as the engine rattles around, needing more power to do the speed as it looses energy from being loose.
And its why triple expansion engines couldn't really be run at full power for sustained periods, you're basically inviting the engine to be damaged and it WILL work to damage itself just through sheer mechanical force. So whilst when commissioned she might have been good for 18 knots, probably 19 if you forced them, that would be reduced by time and wear and tear to probably something around 16 knots and that would probably be her maxium speed but you'd not want to maintain that speed for a long amount of time not with engines made in 1906 and its now 1940.
In the late 1800's Admiral Fisher became the Commander of the Meditteranian fleet, and when he took over, the fleet would normally carry out manouvers at 12 knots and this is with a line of battleships that were all mostly capable of 18 knots at full speed. Because Fisher loved speed, he manged to get the fleet speed up to an average of 16 knots during exercises and this was something that could be sustained for long periods of time, but going to full throttle, you only did that if you REALLY had to and even then for fairly limited amounts of time and forcing them (basically using fans to force more air into the furnaces which gives more fuel to the fire alongside the coal making more heat thus more steam) would be something that would be done either in extremis or during a ships initial trials and even then, this would be for short periods of time as you could cause so much stress on an engine that you'd never hit that speed again without replacing the whole damn engine. Even modern turbine powered ships could do this, on her trials the Battlecruiser Princess Royal flogged the guts out of her engines and hit an impressive speed, but she never hit it again.
Basically forcing an engine is this.

but do that for too long and it leads to this
Whilst the SH in this (dumb) case is rated for 18 knots she's now 34 years old and could probably be good for 16 knots at the most, if you REALLY flog her guts. But she'd probably be able to sustain 12 - 14 knots with a good crew and an engine cheif who knew his engines.

hah all true, cheers for lots of interesting stuff on triple expansion engines!

Hi lighthorse,
I don't think there is any real need to call other members child-like.
Cut it out,
Thanks,
Dom
Sealion threads are something of an in-joke on the forum like the Frisian island invasion or German carriers so we're just continuing tradition
Here's an interesting document on British preparations -
British planning and preparations to resist invasion on land, September 1939 - September 1940.
444 pages here,
https://www.scribd.com/document/853...to-Resist-Invasion-on-Land-Sept-1939-Sept1940
Down around pg 430 there's a series of maps showing the divisional dispositions in Britain by month from November 1939 to September 1940

Obviously seriously incomplete, they don't mention catgirls once!
Tell me more about these alleged catgirls. Do you have any pictures? Would they ride on sealions?
Are they secretly working for British Intelligence?
