We're over a half - a bigger half in addition
Riverine craft (monitors):
510 Krakow - short-range guns #55 75mm vz.02 DFG should be replaced with #33 75mm vz.97 FG - monitors could provide indirect artillery support.
511 Krakow - weapon #139 .30 cal AAMG should be replaced with #204 wz.30 (2) AAMG (as unit 510).
However, weapon #204 is better to be renamed wz.08 (2) AAMG - it is unlikely, that monitors used newest infantry MGs, most probably they were Maxims.
Traditional sources say, that it received 13.2mm (2) AAMG in 1939, but it is not clear, if these plans were really realized. There could be created another unit with 13.2mm AAMG from 1/39 in this case.
It's worth to create a twin monitor
Wilno, also in two (or three) variants.
512 Warszawa - initial armament were #67 105mm wz.13 guns, not 4.7in
Weapon #224 2x8mm wz.14 TMG should be renamed 2x7.92 wz.08 MG - there were no wz.14 Hotchkiss used on Polish ships.
513 Warszawa - it sure wasn't armed with quad 13.2 AAMG (there was no such weapon and it could be removed from OOB). It should be #204 AAMG, as units 511, 512.
Short-range guns #55 75mm vz.02 DFG should be replaced with #33 75mm vz.97 FG
514 Warszawa - same as above.
Icon of 512-514 Warszawa should be changed to 706 (like monitors below of the same type, different from Krakow).
Is there a chance to create real icons of Krakow and Warszawa-class monitors? Now they have Hungarian icons, quite different from their real look. I could provide plans.
516 Torun - same as 513. Photo should be 30300 - now it's Hungarian Sopron.
517 Torun - same as 513 as for 75mm guns, but a photo of late Torun should be 30296.
519, 520 Pinsk - same as 513.
521 Horodyszcze - same as 512 Warszawa (#67 105mm wz.13 guns, not 4.7in)
522, 523 Horodyszcze - same as 513
All monitors from 510-523 had real speed no more, than 14 km/h (now 7 - should be 5, or 6, if we consider Renault FT tank as a lower limit)
It is unknown, why monitors of the same class 512-523 differ in Heat armour. In fact, their armour was up to 8 mm, so maybe all should have basic armour 2, as unit 510 Kraków (there were strict weight limits, since they operated on shallow rivers).
Other riverine craft:
524 Chodkiewicz - same as 513 as for 75mm guns.
It would be best to create an icon of a sidewheel steamer for 524-528 and 531-537...
525 Chodkiewicz - weapon #215 .50 Quad AAMG should be replaced with
two twin #226 13.2mm AAMG (2)
Weapons #224 2x8mm wz.14 TMG should be replaced with two #204 AAMG - it was AA ship.
527 Sikorski - weapon #215 .50 Quad AAMG should be replaced with one #226 13.2mm AAMG (2)
Weapons #224 2x8mm wz.14 TMG should be replaced with two #204 wz.30 (2) AAMG
Full name should be Gen. Sikorski
528 Sikorski - weapons #215 .50 Quad AAMG should be replaced with 2 x #226 13.2mm AAMG (2)
Weapon #224 2x8mm wz.14 TMG should be replaced with 1 x #204 wz.30 (2) AAMG
Speed of all the craft above (524-528) was also no more, than 14 km/h (now 7).
Size should be at least 6 - they were river ships, more conspicuous, than monitors.
529 Lekki Okret - it should be renamed
LKU (Lekki Kuter Uzbrojony - Light Armed Boat; name Lekki Okret - Light Ship is wrong and wasn't used for anything
It should be available from around 1/31 (1/36)
It's definitely too fast (9) - max speed was 11 km/h (4-6)
Crew was 6 (10)

530 Lekki Okret - there was no such vessel with such armament.
It's worth to change it to
KU-30 river motor gun boat, used from 6/39 (and in hot actions), armed with one #226 13.2mm (2) AAMG, armour: 2 all around, speed=14, crew=8, suggested icon: 434

533 Dickman - full name was Admiral Dickman.
Same as 513 as for 75mm guns.
534 Dickman - full name as above.
weapons #140 .50 AAMG should be replaced with 2 x #226 13.2mm AAMG (2)
Weapon #224 2x8mm wz.14 TMG should be replaced with #204 wz.30 (2) AAMG
It was used only until 1937 (now 10/39) - then it was turned into a target ship.
535 Szeptycki - full name was Gen. Szeptycki
Same as 513 as for 75mm guns.
Last date is earlier, than the first one - and it should be 10/39
536 Sobieski - same as 513 as for 75mm guns.
It should be available until 12/31 only, for those, who want to play 1920 war (in fact it was withdrawn in 1920s)
Better photo is 30297 (or 30302)
537 Stefan Batory - It should be available until 12/31 only, for those, who want to play 1920 war (in fact it was withdrawn in 1926)
Guns are better changed to 76mm wz.02 FG, which I proposed to create when writing about artillery.
It apparently wasn't armoured (maybe it should have 1 or 2 armour - now it has 4)
Better photo is 30297 (or 30302) - now it's monitor
Size should be bigger (the same for unit 531 Pancerny)
538 Kanonierka - I suggest name Kanonierka Z (kanonierka=gunboat, they were known as Z-class)
AAMG should be changed to #219 7.92 wz.25 AAMG (or whatever AAMG replacing it), instead of non-Polish .30 caliber.
Speed was actually 10 km/h (now 9 - much too big)
Crew should be 17 (10)
Better icon is 712, with two turrets.

There should be added one fine river craft, which saw action in 1939: heavy armoured cutter
CKU Nieuchwytny ("Uncatchable"). It could be based upon unit 538, with armament: #025 40mm Bofors AAG, 37mm wz.18 and AAMG.
Available from 4/34 until 9/39
Appropriate icon is 679
Speed=7, crew=16
