Thats not what I was saying and you know that.
The point of mentioning the wool was that it add to the weight, thus not having it in the first place will reduce the burden a bit. We are also not talking about complete negation here.
A bit better example of armor swimming (also the only other one I could find), although the armor, at least looks, lighter.
Note what his father/trainer says between 0:50 - 1:10
Okay, it looks like theres a few things you should know.
Japanese Samurai armour is typically lamella or similar and designed to counteract spears, arrows, and swords- The arms race in Japan was focused more on class warfare then its armour, as opposed to Medival Europe, meaning Samurai armour is SUBSTANTIALLY lighter and made out of completely different materials! Samurai armour was also made on a completely different country, on the other side of the world, with completely different resources, and structured to combat completely different threats for a completely different purpose (Killing people in a different fashion, that is). On top of that, each Japanese soldier is a LOT more likely to know how to swim. Why, do you ask? Because Japan is on an island, made up of smaller islands, where you probably want your warriors to know how to swim in case, say, your galley hit a rock - as opposed to Medieval Europe (Or even the map of Altera!); Furthermore... I don't care that they say "it would be easier if he was stronger", he still looks like hes drowning. The armour is heavy.
Lets move on to the medieval plate armour. It was designed in an arms race based on weapons (As far as my knowledge goes, I'm only researching for drawing...). The European age of platemail is not only a different era then Samurai (Knights vs. Horse Archers), but its armour was meant to stand up against things like morning stars, mauls, flails, crossbow formations, pikes... It is therefore a lot more sturdier and I still don't think you could ever conceive to swim in it.
Edit: I also don't think you could concieve to swim in any full armour set, this is why I imagine in stories/folktale/media folks are represented taking their armour off if they land in the drink.
Props to @Naelwyn for helps on details. I'm sorry, Dracon, but I really don't see this debate going anywhere. You in fact didn't even address my main points, previous argument, or pay any attention at all to what I addressed... Which was your specific instance of "Medieval European Knights swimming in Plate Armour" (Which is decidedly not "Samurai Warriors swimming in Japanese Lamella"
To sum up;
Medieval knights in armour + Swimming =
