Pirates of the Visutula

Its the old equal and opposite reaction thing. The force necessary to push a mortar bomb out 3-4,000 meters results in the baseplate being punched in to the ground.

I've witnessed the results of a 4.2-inch mortar crew firing a chain of 30 bombs...and then requiring the crew about an hour of digging to recover the baseplate when everything was finished.

Thoses decks are thin, unless there is major reinforcement, it would not take a large number of rounds to starting bending the plates!

Okay, thanks for the info on recoil - i was just going with the 800 kg weapon limit on the forward hatch.
What about the Vasilek 82mm on the back hatch, is that a no go as well?

The chopper is nuzzled down with the main body in between bulkheads and the tail boom and folded back blades hang over into the next one.
Stacked up a ton of wood on either side, covered it up with camo tarp.

The zu 23-2 is permanently mounted in a pt boat type open turret.

A 120mm mortar might be workable with some jury-rigging. For instance:
The CWS experimented with mortars mounted on landing craft, including the LCIs (Landing Craft Infantry) and LCTs (Landing Craft Tank). It took the view that mortars could support an amphibious assault in the crucial period of an invasion, after the naval and air bombardment let up so that troops could land. Mortars could not be placed directly on the bottom of landing craft since there was no way to keep the recoil from kicking mortars backward when the piece was fired. In addition, the terrific pounding might damage the bottom of the vessel. Technicians rigged an oblong wooden frame, filled with a mixture of sand and sawdust, on the floor of the craft. A thick slab of wood (several sheets of plywood) grooved to take the bottom Y-spade of the baseplate, sat on top of the sand-sawdust filling. The Amphibious Training Command, Camp Carabelle, Florida, to which CWS sent the firing platform, saw the utility of the device and asked the service to design a standard model. [Vol. II, pp. 136-7]

This passage talks about mounting 4.2 inch mortars on Higgins Boats. Such a rig could be used to mount a 120mm mortar on the deck. There should be lots of bracing below decks as she's an ice-breaker and will have lots of reinforcements.

Wisla Kralowa - Using Bunker Fuel

As many of you may know the use of coal/wood for the Vistula Queen has never sat well with me. I grew up among merchant seamen and when I chatted about that vessel's conversion system the general consensus of the engineers and shipwrights I talked to was "it would be easier to build a new vessel".

However, many soviet-era ships used what we call here in Australia "bunker fuel". Bunker fuel is a heavy very low grade oil from the very bottom of the fuel distillation process. It's of no use to vehicles smaller than a locomotive, you can't run a tank or truck on it. It needs to be heated up to 65–120 °C (149–248 °F) to be used and at cold temperatures it congeals into a kludgey, tarry goo. It was used in may places, primarily heavy industry and power generation. It's also extremely polluting which is why it's been largely phased out in many places but it still soldiers on in Russia for instance. It's notoriously horrid stuff to deal with and gets everywhere when being handled, which of course adds to the notorious "Post Apocalyptic Suck".

Now, rather than just brewing up fuel or cutting down trees having a heavy fuel oil used for the Vistula Queen actually adds to the game rather than takes away from it. Limiting options isn't such a bad thing as long as the GM let's the players have multiple choices. So rather than just blithely sailing down the Wisla the players now have to seek out sources of fuel for the tug giving the GM ready-made hooks for scenarios. Looting deserted towns is fun and crawling through abandoned factories or power plants (coal power plants use bunker fuel to get the combustion going) lets the players meet different situations than the usual 'settlement-with-a-problem' or armed mooks.

First off the players are going to need intel. Either the NPCs can have prior knowledge of the area or the PCs can interact with NPCs while scouting. Having one or two Boghammars/gunboats snooping along the river lets the PCs do this. Then they find out if the fuel is either on the river or inland. If on the river the PCs can simply clear the location, secure the resource and then bring the tug up to pump the fuel aboard after heating it.
If it's inland this then requires a dedicated tanker, and I'd be inclined to have them search out a tanker-trailer before leaving. A work truck towing this trailer would be a useful utility vehicle for the game and the truck could come in handy if the players also need to do any other repair, rebuilding or construction jobs in the game (and they should!)
Remember this stuff needs heating before it can be pumped out and recovered and the area it is found in may need repair or rebuilding before it can be heated up. This not only allows more encounters while this noisy process is undertaken but also allows the PCs to interact a bit with the environment such as scrounging.

This fuel gives the GM a little bit more narrative control. The PCs can have a hard limit put on their mobility, the GM can add a little tension as fuel stocks run low and it also forces the PCs to get out and look around more. A whole micro-campaign can be built just finding a good amount of fuel that opens up movement.

Here's some ideas to finish up with:
- Some NPC group has recognised the fuel's worth and has already recovered it when the PCs arrive to secure it. They can trade, negotiate or secure the fuel via violence/stealth.
- The facility storing the fuel has suffered an airstrike and is dangerous because of contamination, hazardous ruins, unexploded ordnance or a combination of these things. The PCs must deal with the dangers using their skills.
- A fuel source is now being used by a community of civilians and their militia and they are planning to use the fuel to kickstart a bit of light industry and at the very least for heating during the upcoming bitter winter. Who's need is greater?
- The PCs find some fuel but it is contaminated and requires a specialist chemist, an engineer and specialist distilling gear to clean.
- An NPC group is also running a ship and needs the same fuel, they might be in a race with the players to secure stocks. When the PCs negotiate somewhere this group might attack or try and outbid the PCs, if the PCs are too strong they might tip off nearby OPFOR units to the PC's presence. This group can be fleshed out and be great recurring rivals. Maybe some times they come to the player's aid if the player's are outmatched in exchange for sharing?

Pretty sure it can also be used as heating oil?

Which means is would in more demand thank you might think

this thread help me. Thank you guys.

What the tug and barge could be too
