Muscatatuck,

Welcome, your BC can be shrunk down to about 150-160 Meters thereby halving the amount of funnels an still ending up with a decent sea boat.

Yet another update, inspired by several other artists to make a better drawn vessel, that and I realized I made a few slight errors.

Welcome to ship bucket ! :D

Personally I would allow BCs (they make just as much sense for a smaller navy than a BB and prestige wise they count the same pre war), but yours is just a bit big (ie its a 1914+ design R&R style very much not a 1908 ship)

As to the details just cut the size of ship and guns to say 20,000tish and 12" and you will have much more balanced 1908 ship.

BC's / Fast BB's, are certainly allowed, just not too big.

If you try something with 8-10x12" or 8x13.5"/14", that will fall in with the armaments of the ships already posted in this thread.

With your drawing, the bridge / mast structures look very good. As others have commented, a few too many funnels, 2-3 would be enough with a smaller armament. A good beginning. Don't get caught up in the 'gigantic' first drawing syndrome.

With picture hosts, I have been using dropbox.com for the last 12 months or so and I am very happy with how it works. There is a tutorial or two to help you get used to using it on Shipbucket.


Nighthunter - your ship is looking better all the time.

How how feasible is in route replenishment during this time frame?

You are talking about bags of coal moved by hand, ie not going to happen unless in a still anchorage and even then slowly. (unless I'm mistaken ?)

Pressurized bunker oil, could it be pumped into a pressurized cell, say 15 psi?

In the time frame I think you are going to be coal fired ? (1905-10) (Nevada/QEs the first all oil BBs was laid down in 1912)

From what I can find, oil fired boilers use simpler fire box of venturi like jets unlike coal which uses grates that must be cleaned and ash removed, also from what I understand forced draught can be easily implemented unlike coal as well, and the Tribal(F) class were all oil in 1905.


Edit: figured I'd just add this instead of new post,

I think it will fit better now, but want more advice before I start drawin again :oops:

Yes you could have oil fired Battleships earlier than 1912. So why didn't they? The answer is that oil fuel was not available in most ports in the world. In the seven years between 1905-12 the infrastructure required to support oil fired ships would need to be built and implemented around the world. Tankers to carry the oil for the fleet needed to be built. There was also a fear that oil may not be able to be supplied to the fleet in the amounts necessary during time of war. Coal was much more readily available 1905-12

Be careful when using 20/20 Hindsight, that you remember all the other changes necessary to implement a new innovation.
