180ton Firanji competition

[Korpen]

In the second half of 1915 Firanji had 0,18BP left over to spend, and this was used for a single experimental ship. It is for that ship this competitions is held.
The Requirements:
-Unique
- 1916 engines
- max 180 ton light
- should be capable to either perform some unique mission (such as carry and fire a 33cm gun), or a more mundane mission in an original way.

Weirdest and most original ship will win, but some kind of functionality is a must.
Considering the nature of the experimental ship, it will be huge bonus to include a drawing. Original looks can go along way on an otherwise conventional design.

[Korpen]

The first of two in house designs:

Codename: Sane
Intended to operate like a submarine that cannot dive. To compensate for lack of diving she is covered with a 2cm armour (backed by 2cm wood and 12mm hull plating), enogh to keep all smaller HE and shrapnel out.

2nd in-house design.
A slightly more daring design, intended to single-handedly give Firanji and amphibious warfare capability. She is propelled trough water by eight paddle wheels each with its own 350hp electrical engine. The design of the paddlewheels is such that when the reach the beach they will support her as leaves the sea and travels on land, in case of soft ground there are a number of non-powered support wheels under her hull (not seen in picture). This will allow her to lead landing soldier kilometres inland, using her machineguns to scythe down enemy infantry and using the full-power 14cm gun to blast apart enemy guns and strongpoint as she grinds the foes under her mighty wheels.

Well, that is the sales-pitch at least.

A somewhat...saner approach is this one. A superheavy mortar mounted in an olde-fashioned barbette for use on the rivers and lakes. Given the short barrel of the mortar there would probably be more shells than the SS report says...

I'm not sure the range would even allow the sub to reach Swiss Australia.

[Guinness]

Well, I suppose if deployed on the lakes it would be ok. How big are those lakes in Australia anyway?

[The Rock Doctor]

Got me there - I was thinking like it was ocean-going.

[Borys]

The lakes are very big. Think Ladoga, Baikal, Rift Valley Lakes, the large North American ones.
Small inland seas, they are.

[Guinness]

Well, if they are approx. the same size as the N. American great lakes, the longest straight line distance from one side of a lake to the other is about 300 miles, so I suspect the range would be adequate for a number of missions.

[Guinness]

A new type of coast defense boat. The boat has a very shallow draft to allow it to be positioned in coastal, river or lake waters in advantageous locations to ambush the enemy. It has a relatively low profile as well, and can be easily camouflaged. Capstans and anchors are used to maintain position, and the boat can cruise relatively long distances to reposition.

The torpedo battery is fixed to starboard, and each tube is very slightly angled from the beam to produce an effective spread. Up to 18 tubes at one time would be fired in one salvo.

The boat is armored against most torpedo boat shellfire to offer some protection against the most likely counter, and carries a 75mm gun to provide some defense against small fast targets.

It is anticipated that this design could be quite useful on Australia's great lakes, as well as inshore around Firanji's coast.
