Need help/opinions on how to make a card for the H45

In generally I would recommend trying to scale it around the forumini guidelines.

For Hull Points that might look like this:
At least as far as upper limits go, the guidelines have each hull point cap at in a sort of relationship (Hull 3 stops at around 15000 tons, Hull 5 starts at around 30000, Hull 6 stops at around 60000. Estimating 280000 tons for H45 (comparing its beam and length to Bismarck) Hull 8 starts at 120000, Hull 9 stops at 240000, so 10 Hull Points looks about right.

For mains guns (800 mm if I am remembering correctly), there is usually a 1:1 or near 1:1 correspondance between main gunnery dice at range-0 and the gun's calibre in inches, with variations based on nationality and the number of guns (10 or 12 eight inch guns on Haguro or Baltimore through 10 dice, but 8 eight inch through nine dice on Suffren and Norfolk). H45's guns would by this metric through about 30 dice at range-0, and will probably suffer pretty badly outside of range-1 (look at Yamato's dice drop off, or better yet, Tsushima's. Big guns don't tend to hit things that are far away because of their slow rate of fire). Note that H45 could fire a full main battery salvo once every 3-5 turns, which you should also factor in.

As far as main battery range, secondaries, armour, and vital armour go, I'd recommend following a similar line of comparison.

Good luck making a card, and let us know (once you've made it) how she fares on the tabletop!

Interesting point on the dropoff from a distance, otherwise German guns tend to keep their high scores. I think he statted his like 21/21/19/18 or some such.

She wouldn't be able to go through the Kiel Canal, and considering her draft, probably couldn't make it through the straits of Denmark either.  So it would basically be a coastal battleship in the Baltic.  Not to mention that there is no drydock on Earth at the time could fit a ship that size, so God knows what they'd do once the thing got hit by a torpedo (considering its turning circle would probably be measured in minutes of latitude and longitude).

The British (fantasy Iceberg) Habakkuk is a little more believable than H45... Until it melted and raised the sea level by half an inch.

Holy moly. It's good though, just pit this against the Habakkuk for the lolz.

But wowwie, that is a massive print. Dar I ask how much that was/ how and who printed that? Bismarck/Tirpitz are larger ones at 1800 scale around what, 5 inches? This looks at least 12 inches long.

13.3 inches.... yeah no way that's fitting in my tacklebox of minis.
But it goes on the christmas wishlist, that's for sure. Absolutely incredible.
