Hi Onno,
The Hayes book on the HMS VICTORY can only be presumed to be better than
the Millenium Falcon, since I never purchased the book in which to compare.
;)
Having said that, I have several books on the HMS VICTORY along with a few
books on various other ships. The Hayes book has details I've not been able
to gather from my sources until I picked up that particular book. That is
why I would heartily recommend it.
The Construction and Fittings of the ENGLISH MAN OF WAR 1650~1850 by Peter
Goodwin is a rather meaty read, but contains bits and pieces of information
you might find useful if you're interested in the Age of Sail material. If
not, I wouldn't suggest you pick it up just because.
What you will find however, is information on the support beams required to
handle the weights of the guns which will vary by the gun itself. The book
also gives a few formulas here and there that might be of interest if you're
interested in understanding why the gun deck length was as it was. There is
even a formula for one to determine what a gun deck should be based upon the
guns the ship will be carrying - if that is worth knowing. :)
Just a peek of what was involved:
42 lbr used a gunport that was 3'6" wide. The working room required for the
gun was 7'7"
18 lbr used a gunport that was 2'11" wide. The working room required for
the gun was 6'7"
09 lbr used a gunport that was 2'4" wide. The working room required for the
gun was 6'8"
I have the information for the 42, 32, 24, 18, 12, 9, 6, and 3 lbrs in that
book (page 4 so I don't have to go digging for it in the future if months
from now!).
Let me know if there is anything else that I could maybe provide for you.
Hal

Hello Hal,
thanks for you mails, but keep in mind that I'm increasingly departing from
history in my designs.
The steam sloop is pretty close to history, cf HMS Gorgon (1837), except
that I'm suggesting in the text that she could have come earlier. The rules
don't discriminate between 1800 and 1840 steam engines, they're all "early
steam".
The steam ship of the line is actually smaller than the first screw
battleships, being based on an 1800s third rate instead of an 1830s first
rate. Again my color text points out that the steam engine is "plain
vanilla" TL5 and available as of 1800; of course the screws are listed as
late TL5.
The next one is based on a historical design which was never launched, and
the one after that will go completely off the rails if she works out as
planned.

Right now I'm wondering how to GURPSify a pivot mount on the deck of a ship.
One idea was to place a carriage-mounted weapon in an open mount.
VE102: A carriage mount is not required after early TL5. Does that mean it
is still allowed?
VE12: A carriage-mounted weapon must be mounted "concealed within the
vehicle", which increases the volume, but the same applies to ranged weapons
in a highly streamlined vehicle -- obviously the concealed mount is not
restricted to gun ports in the hull, but it sounds weird to conceal
something in an open mount.
The other idea was to assume that proper pivot mounts are a mid-TL5
development, and to GURPSify them as a muzzleloader without carriage mount
(which is not required any more, see above), mounted in an open mount. That
saves half the weight and even more volume, but it might not be justice to
the recoil mechanism.

I've got the Osprey book on the British Napoleonic Ship-of-the-Line, Brown's
Warrior to Dreadnought, and Conway's Steam, Steel and Shellfire.
I'm thinking about Brown's Before the Ironclad, but the reprint is 39 EUR on
amazon.de. Too much for an impulse buy.
I have a Haynes on the Millenium Falcon and was not very impressed by that
-- it feels written for a younger audience. Are the historical ones better?

4E has some problems, especially with the scaling of HP, but also the chance
to do some other things better. I wait for a new vehicle design book.
The old Vehicles 1st had (!) notation for low-velocity roundshot, not to be
confused with the (!) for Traveller meson guns. They allow low penetration
with high raw damage.
Regards,
Onno
