Zionite testbed

[Desertfox]

A pretty normal patrolboat with a very unusual cargo.

Note: She does not have 10" torpedoes, they are just there to account for deckspace.

   Ship tends to be wet forward

Ship space, strength and comments:
   Space   - Hull below water (magazines/engines, low = better): 90.0 %
      - Above water (accommodation/working, high = better): 70.3 %
   Waterplane Area: 1,281 Square feet or 119 Square metres
   Displacement factor (Displacement / loading): 155 %
   Structure weight / hull surface area: 22 lbs/sq ft or 106 Kg/sq metre

   Excellent seaboat, comfortable, can fire her guns in the heaviest weather

5 Tons "Trumpets of Jericho"
5 Tons Special Room
5 Tons Structural reinforcements

It's kind of difficult to comment without knowing more about the payload.  A gigantic air horn for sounding alarms?

[Desertfox]

No speculation?

Its five, 10" diameter, 9 meter long tubes...

[The Rock Doctor]

I did speculate.  If you're proposing some wacky scientific invention, you'd be well-advised to run it past the Mods before you go too far with it.

[Desertfox]

But, yours is the only one, pretty close too.

This ship is only for fun. While the physics for the concept work, it would be very hard to implement succesfully in practice, even today.

[Jefgte]

Building small torpedoes is not an invention.
It is the use of existing technology to produce a smaller version.

[Sachmle]

It's not torpedoes he's shooting out of that, or there wouldn't need be a "special room" or "structural reinforcement", more likely some kind of early rocket.

[Jefgte]

...early rocket., interresting idea   8)

Jef  ;)

[Korpen]

I think it is whipped cream siphons (everybody knows thay are a bit kinky in africa). Next class of cruisers will carry the oven to make the rhubarb pie itself.

[The Rock Doctor]

It better not be - New Zion's nowhere near that far along in the Baking Tech Tree
